Robotic gearbox mitsubishi outlander. Overview of the CVT on the Mitsubishi Outlander

Car service "Respect Auto" provides high-quality inexpensive repair of Mitsubishi cars in Moscow, including maintenance and repair of Mitsubishi Outlander crossovers.

Mitsubishi Outlander is an excellent car for the inhabitants of modern cities, it has excellent handling, excellent cross-country ability and, thanks to its high ground clearance, makes it easy to overcome bumps. Among other things, the car is characterized by increased comfort and a high level of safety. Drive Mitsubishi Outlander - Full Time 4WD with self-locking center differential, allows you to optimally distribute traction between the axles, depending on changing road conditions. Independent suspension for each wheel provides precise handling and stability when cornering and at high speeds.

On the other hand, the steering column is now adjustable in both height and depth, and finding a comfortable driving position is much easier; In addition, the seats hold the lumbar and lateral areas well. However, when this car feels better, it fluctuates between 000 and 200 rpm. In this area, the reaction to the accelerator is very fast, and the car gets a lot of speed. We can't judge their behavior in the field because we barely covered a couple of kilometers for review and the dirt track was in very good condition.

One thing that attracts a lot of attention is the low noise level that is perceived inside the cabin at any speed, which makes the journey perfect and not annoying. However, almost all of this is due to the engine itself, which vibrates very little and is very "discreet". In fact, if we open the hood, we do not see large pieces of plastic or soundproofing plates.

Auto service "Respect Auto" is equipped with dealer diagnostic equipment, recommended special tools. The specialists of the center have extensive experience working with Mitsubishi cars, including those of official representatives, they are perfectly familiar with the peculiarities of the repair and maintenance of Mitsubishi of various models and years of manufacture.

Prices will not be available until October, when it goes on sale in our country. Your main rival? In the meantime, we leave you with the impressions that caused us during the first contact on the roads of the Levantine coast. While it is true that my interest has been focused on its extended range of all-electric autonomy, its hybrid powertrain and the official emissions it consumes.

The Japanese have a good product among their ranks. In it, we also appreciate important changes, especially in terms of sound insulation. The feeling is like stepping into another atmosphere of silence, especially when moving. Both are powered by 12kWh lithium-ion batteries that take 5 hours to fully charge in a household electrical outlet, while fast charging can be completed in as little as 30 minutes.

With a high level of quality of services provided, the management of the center also pays great attention to its accessibility. We draw your attention to the cost of repair Mitsubishi Outlander >>

On the other hand, we have the "Save" mode, which saves battery power for later use. In this mode, the gasoline engine or internal combustion engine is running to prevent the battery from being drained. Noise levels are very low and allow other aspects of the environment to be assessed. The performance of its mechanics matches its specifications, but what really surprises is the consumption in the combined cycle. At full battery level, it's easy to write down the official costs, and once you've exhausted the battery, the consumption isn't much higher.

Gearboxes in action: "Mechanics" or "automatic"? "Robot" or "variator"? The problem of choice one way or another confronts every motorist who chooses a new or used foreign car.

So, the types of gearboxes:

1. Classic "mechanics"
2. Robotic mechanical box
3. Automatic transmission
4. Transmission automatic variator

Consider the features, typical breakdowns and the cost of repairing a gearbox using the example of two brands - Hyundai and Mitsubishi. An expert will help us with this - Sergey Dmitriev, head of the locksmith shop of the Hyundai service center of the BLOCK company.

The fault is the hybrid system, because the electric motor that is responsible for advancing the rear wheels does not allow you to fit two extra seats in the trunk, and also does not allow you to equip a spare tire that has been replaced by a puncture repair kit.

The first thing that stands out for everyone who climbs this SUV is its low noise level, which makes rolling with this model especially enjoyable. This is one of the aspects that the brand claims to have improved and the truth is that it shows from the first meters and above all when we demand maximum power for acceleration.

In terms of performance, the classic manual gearbox is in the lead: it is with such a gearbox that you can achieve maximum fuel economy with an appropriate driving style. The maintenance of the "mechanics" comes down to a scheduled oil change of a small volume (usually about 2.5 - 3 liters, the cost is about 500 rubles per liter), and the resource, if used correctly, goes far beyond the warranty mileage of 100 thousand km.

The suspension is soft and filters the bumps very well, but at the same time prevents excessive body swing. In any case, you should know that this car is not designed for spirited driving, because it clearly prefers comfort, and also in this situation you will not be able to use your propulsion system. A system that is ideal for those who normally travel in urban areas and at certain points make a strange journey on the road.

This is theoretical, because in practice you will find it difficult to cover 33 kilometers using electricity as your only source of propulsion. And as soon as the load is exhausted, fuel consumption rises. If you intend to use it mainly in the city, with specific breaks throughout the year, this shouldn't be a problem. The low cost you get on a daily basis makes up for the extra cost of using this car on long trips that can drain your battery.

Of the typical malfunctions of the mechanical box on Hyundai cars, one can note the noise of the input shaft bearings, the wear of the axles of the differential satellites, as well as the wear of the release bearing guide on the "younger" models - Gets, Accent, Elantra, Matrix. These breakdowns are usually caused by rough operation of the unit and can occur with a run of about 50-60 thousand km. The cost of repairs in this case is about 45 - 60 thousand rubles, which again depends on the general condition of the checkpoint. Manual gearboxes of the "older" Hyundai models - Sonata, Grandeur, Tucson, Santa Fe, H-1, etc. - are much more reliable, they did not have any massive malfunctions, despite the fact that the mileage of many cars has exceeded 250 thousand km.

Classic manual transmission

And in the case of cities like Madrid that enforce traffic restrictions when pollution levels are high, you can always access the center. That being said, it takes about four hours to fully charge, and when connected quickly, the time is reduced to 30 minutes to reach 80% of the total. Of course, the brand, as usual, does not recommend using this system, as it reduces battery life.

If you don't want to plug it in regularly, it offers other battery charging formulas, although they are much less economical. The second option, which uses deceleration to recover energy, is not as efficient, but it is very practical. And is that in addition to doing it automatically when we raise the accelerator foot, it is possible to change the level of hold with the help of those who are behind the wheel. In this last case, there is practically no need to brake, since the braking speed is very high.

The manual gearboxes of Mitsubishi cars are also very reliable; our company has never dismantled the manual transmission of some models for repair. The only exception is the gearbox of the LancerX car: on this model, the rumble of bearings is often noted with a relatively small mileage of 40-50 thousand km.

As the BLOCK service center specialist emphasizes, unlike an automatic transmission, "in addition" to the "mechanics" we get a clutch assembly that has a certain resource and, accordingly, requires repair when the resource is exhausted. The cost of repairing a manual transmission clutch unit in some cases can be comparable to the cost of repairing a manual transmission.

Mitsubishi doesn't go with little girls, and the brand doesn't want to give up on a plot where they were once the protagonists. Mitsubishi wants to become a level playing field in this segment and so the brand was clear that it needed to evolve. This lowers the entry price and aims to include a younger customer. Few changes, but they are relevant. The front fascia changes slightly with a new grille, LEDs and chrome in various areas of the vehicle. On the reverse side, the optics changes its appearance and is built a little into the gate.

Gearbox "robot" (robotic box)

It would be logical to put a robotic gearbox next on the list. In fact, a "robot" is a conventional mechanical box controlled by a computer with the help of special electric drives - the so-called actuators. The asset of this box has all the advantages of "mechanics" plus the function of automatic gear change and the absence of a clutch pedal. Among the shortcomings are some "thoughtfulness" when switching (the problem is partially solved by changing the control program), rapid wear of the clutch disc (sometimes replacement is required at a run of 20-30 thousand km), as well as low reliability of actuators and sensors at their rather high cost (The clutch drive actuator costs about 25 thousand rubles, the gear selection actuator - about 35 thousand rubles, the gearbox fork position sensor - about 7 thousand rubles). In practice, the disadvantages outweigh the advantages of the "robot", and that is why gearboxes of this type are not widely used and are usually installed only on the smallest models of the range. In particular, Mitsubishi has a “robot” only on the Colt model, while Hyundai does not equip its cars with such gearboxes at all.

It also restyles the bumper to make it look wider. What has been converted is the length, to reach 4.69 meters. In a test done on these access models, we found the front seats to be a big improvement. In the back, the seats have plenty of legroom, which is appreciated on intermediate and long trips. The backrests can be reclined for added comfort. Trunk volume is 550 liters, which can be increased by folding down the rear seats to reach 718 litres.

It has luggage storage rings and has a double bottom floor that allows you to store a lot of stuff out of sight. Body rigidity is another modified aspect. This change is noticeable when handling the curved area, offering more comfortable dynamism than the previous generation.

Gearbox "Automatic"

An automatic gearbox of a classic design is a unit that is more expensive to operate due to a slightly larger amount of oil to be replaced (usually about 4.5 - 5 liters with a partial and 6.5-8 liters with a complete replacement, the cost is about 350 rubles per liter ) and higher fuel consumption (about 0.5-1.5 liters) due to the presence of a torque converter and associated hydraulic losses. Of the characteristic malfunctions of automatic transmissions of younger Hyundai models - Getz, Accent, Elantra, Matrix, as well as in the case of "mechanics", one can note the wear of bearings, the axles of differential satellites, which manifests itself with a run of 60-80 thousand km, as well as wear of the bearing bushings of the front clutch package, leading to damage to the oil pump, which in turn causes a drop in oil pressure, friction slippage, their destruction and, as a result, requires a complete overhaul of the automatic transmission (90-150 thousand rubles). This malfunction is typical for "machines" produced before 2005, with a run of 60-80 thousand km. On boxes manufactured after 2005, a bearing was used instead of a bushing, and this problem is no longer observed.

It has important safety features such as driver's knee airbag, brake assist as well as hill start assist. It also introduces elements that other competition models may show as optional on access versions, such as a reversing camera, levers behind the steering wheel, and dual-zone climate control. From our point of view, this is a very good buy based on the performance, hardware and price offered.

With this presentation card, we can already guess that the propeller will not be sugar cane, but efficient. The engine has a good power supply, it has claws. It offers good performance both on the road and on forest roads. The suspension is somewhat soft but becomes an ally on dirt roads as it makes the car much more comfortable. It only has front wheel drive, but it's not a problem to be effective on all terrains. The price is 400 euros and the only option is metallic paint.

"Automatic machines" of older Hyundai models, like mechanical boxes, are more reliable than those of younger ones. Of the typical malfunctions, one can note the destruction of the third-fourth gear clutch package on Tucson cars with 2.0 and 2.7-liter gasoline engines, which also leads to the need for automatic transmission bulkheads. On Elantra New cars, there were cases of failure of the hydraulic control unit of the box (repair price - 40 thousand rubles). Sensors that measure the speed of rotation of the automatic transmission shafts also fail, which, in principle, is not an expensive repair (5-7 thousand rubles).

The car then received a technical sophistication and saw its safety systems improved. Finally, the behavior of this new generation was placed under the sign of gentleness. One might have thought that this model would have some success, but it did not, at least not in the way the builder had hoped. And the reason was obvious. The front end had a special appearance that discouraged potential buyers.

It was necessary to come up with something more substantial. Two chrome horizontal rods form a new grille that overlaps with a black section whose slots allow air to enter the engine bay. In the cockpit, we spent a lot of time modifying parts while improving the quality of the materials. The information screen has simplified controls, and a photochromic mirror is available on select models. Please note that a third row of seats can be ordered through certain equipment configurations.

Mitsubishi automatics are very reliable. The exception is the boxes of the Pajero 3 and 4 models, in which there are cases of destruction of the planetary mechanism, leading to damage to many expensive parts and entailing the replacement of the assembly assembly (repair 150+ tr.).

Transmission variator

The variator is the most expensive unit to operate (the amount of oil is from 3.5 - 4 liters with a partial replacement and about 8 liters with a full one, while the cost of one liter is 1000 rubles). The variator is designed in such a way that when the car is moving, the engine operates most of the time in the zone of optimal torque output. Theoretically, this has a positive effect on fuel consumption and reduces emissions of harmful substances, however, it is not fully realized due to the mandatory presence of a torque converter (albeit smaller than the “automatic” torque converter) and the associated hydraulic losses. In addition, the main variator assembly - the belt and the pulleys associated with it - have a small resource and, during active operation, sometimes begin to slip at a run of 80-100 thousand km. Only a few parts of the variator are supplied as spare parts, the belt and pulleys do not belong to them, respectively, if these parts fail, the variator assembly is replaced. Also in the case of the variator, there are cases of failure of hydraulic control units (repair costs about 80 thousand rubles).

Considering its size, this is the place to troubleshoot. In short, this new generation has acquired grace and sophistication. In fact, all mechanical elements have been updated and improved. However, this year, 26% less torque loss from this transmission provides faster acceleration and response while reducing fuel consumption.

It is recommended to use super gasoline. Eco Mode: The front drive wheels are used most of the time before transferring some torque to the rear wheels in the event of a slip. Auto mode adjusts torque in proportion to the wheels that have the most grip.

The CVT gearbox on Mitsubishi Outlander cars is no less popular than other types of gearboxes. Indeed, according to Japanese engineers, such a transmission is not only very convenient, but also quite reliable. However, the opinions of motorists on this matter differ significantly. Therefore, in order to find out what the Mitsubishi Outlander CVT actually is (owner reviews, main malfunctions, operating rules, etc.), we will analyze all its advantages and disadvantages in the article below.

Device and principle of operation

The variator on the Mitsubishi Outlander 2 and 3 generations consists of 4 main mechanisms:

• Two belt-driven pulleys (serve to transfer the rotation of the crankshaft to the wheels while driving. In the neutral position of the box, this mechanism ensures the separation of the motor and gearbox);
• Case (serves to protect the mechanism);
• Planetary device (responsible for the correct rotation of the pulleys when the crossover is reversing);
• Gearbox control system (serves to move the driving and driven pulleys in order to change their working diameter).

In a standing position (in neutral gear), the variator belt is located in such a way that the drive pulley has the smallest diameter, and the driven one, on the contrary, has the largest one. But when accelerating, the diameters of the pulleys will gradually change, tending to the opposite indicator (the driving pulley to the largest diameter, and the driven pulley to the smallest). This, in fact, is the whole principle of operation of the CVT. Well, what advantages does it have compared to an automatic and manual transmission, let's look further.

Advantages and disadvantages

Compared to a manual transmission, the variator on the Mitsubishi Outlander 3 and 2 generations has a clear advantage in ease of use. Indeed, when driving in dense city traffic, the driver will not need to be distracted by gear changes, which will allow him to fully concentrate on the road. But against the background of the automatic gearbox, the CVT gearbox boasts other characteristic features:

• More rapid change of speeds;
• Invisible switching (unlike the machine, on the variator, when switching from one speed to another, shocks from the side of the box are not felt);
• More dynamic acceleration from a standstill;
• Economical fuel consumption.

However, the variator on the Mitsubishi Outlander, according to the owners, has one serious drawback - difficulties with repairs. And the reason for this phenomenon is: the lack of necessary parts in stores (due to which the owner of the crossover has to wait for the repair to be completed for about 2-3 weeks), and the rather complicated design of the mechanism.

How to properly operate the CVT

We have already mentioned that the repair of a CVT gearbox is a serious problem that takes a lot of time, effort and money. Therefore, in order to avoid the above troubles, motorists should find out in advance: how to drive a Mitsubishi Outlander CVT so that its wear is minimal. And the following tips can help you:

• Avoid dense traffic and off-road (in practice, the variator has repeatedly proven its instability to high loads, so testing it in such conditions is strongly not recommended);
• Do not use the crossover as a tug for other vehicles;
• Timely undergo box maintenance (according to the passport, the variator requires an oil change after every 60 thousand kilometers);
• Do not overheat the gearbox (when the box overheats, the CVT light will light up on the Mitsubishi Outlander panel. If this signal is ignored, then the breakdown of the gearbox will not take long);
• Use only high-quality oil and high-quality gasoline (poor-quality technical fluids contribute to the rapid wear of the variator cone, due to which the belt will periodically slip during switching).

At the same time, it is desirable for all owners of a Japanese crossover to know: which variator is on the Mitsubishi Outlander. Indeed, in the event of a breakdown, there is a high probability that the mechanism will have to be replaced completely. And in this case, you only need to buy the original gearbox from Jatco (model JF011E). Since the manufacturer does not give a guarantee for analogues of Chinese origin.

Weak points of the mechanism

Before buying a Japanese crossover of the second or third generation, many motorists are often interested in the question: how much does a CVT cost on a Mitsubishi Outlander. After all, it is quite difficult to repair such a mechanism. And it can become unusable for several reasons:

1. Overheat. As practice shows, the Outlander model has a very weak resistance to overheating (especially in summer). But this problem is easily solved by installing a separate cooling system on the air conditioner;
2. Severe bearing wear. Bearings are the weakest point in the CVT, which, if used incorrectly, will definitely make itself felt after 10 thousand kilometers. Well, you can avoid such a phenomenon if you do not operate the crossover in off-road conditions and do not overload it with sharp jerks from a stop or sudden braking;
3. Belt stretch. In addition to bearings, if the gearbox is not used correctly, the belt may also wear out. And it’s quite simple to find out about such a breakdown: in the area where the driver’s legs are located, a strong vibration will appear, accompanied by a hum (during acceleration, vibration and noise increase noticeably). At the same time, eliminating such a seemingly trifling problem is not so simple. Indeed, in order to remove the belt, mechanics will have to prick the box. And not all masters undertake such work.

It should be noted that regardless of the reason (be it a stretched belt or a worn pulley) that required you to replace the variator with a Mitsubishi Outlander, the cost of work will be approximately the same. And it will cost the owner of a Japanese crossover approximately 90-100 thousand rubles. Therefore, it is better to operate a CVT-type gearbox according to the rules outlined above.

The CVT transmission belongs to the class of continuously variable transmissions. Cars began to be equipped with such gearboxes relatively recently. The Outlander variator is a structurally complex unit that requires careful use and timely maintenance. We will discuss this, as well as the shortcomings of CVT transmissions, below.

[ Hide ]

Device and principle of operation

First, let's look at how the CVT gearbox works in a Mitsubishi car 2008, 2010, 2011, 2012 and other years of manufacture. The principle of operation is based on a smooth change in the torque of the power unit in the adjustment intervals established by the manufacturer.

CVT Outlander disassembled

The Outlander variator includes the following elements:

• the variator itself;
• clutch mechanism;
• reverse speed activation device;
• control module.

In new and old Outlander machines, the operation of the CVT gearbox is controlled by a control system that is designed to perform the following functions:

• clutch control, determining the moment for separating the gearbox from the power unit;
• control of the functioning of the planetary device;
• change in the gear ratio between the transmission shafts;
• ensuring the operation of the reverse device to activate the reverse gear.

The principle of operation of the CVT system in cars 2013, 2014, 2015, 2016 and other years of production is based on the simultaneous change in the diameters of the driving and driven pulleys. The dimensions of these elements are changed by means of a special drive. At the moment when the machine is stationary, the drive shaft has a small diameter, and the driven shaft has a large diameter. As a result of the start of movement and an increase in the speed of the power unit, the dimensions of the elements change. As a result, the diameter of the drive shaft increases, and the driven one decreases.

The control module of the transmission system receives data from various controllers. The operation of this device is related to the speed parameters of the power unit, the tire pressure, the operation of the ABS anti-slip system, etc. The data received by the central processor is filtered. Therefore, the control module automatically adjusts the operation of the unit to a certain gear ratio. A key feature of the Outlander CVTs is that such units cannot independently activate reverse gear in the car. To implement this function in vehicles, a planetary gearbox is used. Its principle of operation is similar to the functioning of a traditional automatic transmission.

Outlander variator circuit

When the driver of a car with a CVT drives a vehicle, he performs the same actions as when working with a machine gun. But in this case, the motorist only needs to select a certain mode, the control system will do the rest for him. With the help of the central processor, you can fix the gear ratio.

When accelerating the vehicle, the crankshaft usually runs at one speed, because of this, many owners in their reviews scold the variator because they do not feel the acceleration of the car as a result of a smooth increase in speed.

This scheme of work is relevant for all Outlander models, regardless of mileage and year of manufacture.

Main malfunctions

Now let's look at what problems and malfunctions affect the duration of operation of CVTs in the Mitsubishi Outlander:

1. Wear of cone bearings. In the event of a failure of the bearing devices, the operation of the CVT transmission is accompanied by a hum and noise. In practice, parts can fail after 50 thousand kilometers.
2. Breakage of the variator circuit. Outlander transmissions use metal belts, consisting of steel plates connected to each other by means of special tapes. The strap contacts the sides of the tapered pulleys. On the latter there are special notches designed to improve grip. If these elements begin to wear out, this will lead to the failure of the unit. Experts recommend checking the condition of the circuits from time to time.
3. The need to repair the transmission unit may arise if the input controllers break down. We are talking about the transmission oil temperature sensor, the rotation regulator of the driven and drive shafts, the pressure controllers in the main line, etc. If the devices break, this is due either to their wear or mechanical damage. Sometimes the cause is liquid getting on the controller.
4. Malfunctions in the operation of the electronic control system. With such malfunctions, difficulties may arise with the inclusion of different modes of operation of the checkpoint. Often, when the electronic unit breaks down, the gearbox works with jerks and kicks, vibrates.
5. Malfunctions in the operation of actuators and devices. We are talking about solenoid valves for pressure in the main line, as well as in the driven pulley, planetary device, etc.

In the video of the Ambulance channel, your unit shows the process of repairing the Outlander transmission.

Troubleshooting

You can check for errors in the operation of the gearbox through computer diagnostics. To do it, you can contact the service station or try to do everything yourself. To determine the problem, you will need a laptop with a diagnostic program, as well as an adapter to connect to the diagnostic connector. Connecting to the plug, the test utility is launched, which counts all the fault codes remaining in the memory of the control module. By these codes, you can decipher the problem.

How to solve problems in the operation of the checkpoint:

1. Failed bearing elements must be replaced. Their operation in a worn condition will lead to destruction. As a result, bearing wear products can clog the channels of the CVT lubrication system.
2. In order to prevent a serious problem, it is necessary to periodically check the condition of the circuit. A broken belt must be replaced.
3. Input sensors fail they are infrequent. Typically, a malfunction in their operation is associated with damage to the wiring to which the controller is connected, or in damage or clogging of the connector. If the operation of a particular sensor causes problems, it is necessary to dismantle it and check the quality of the connection. Usually, after cleaning the contacts, the malfunction disappears. If both the contacts and the wiring are intact, then the sensor needs to be replaced.
4. In case of problems with the operation of the control module, it is necessary to contact specialists. At home, solving the problem of the non-working state of the central processor is problematic. First of all, you will need to reflash the device, update to the latest software version. If this does not help, more detailed diagnostics will be required to identify errors. If the unit has mechanical damage or is exposed to moisture, then the cause of the failure may be a board failure. Only a qualified craftsman with the appropriate equipment can re-solder the circuit. A board that has failed and cannot be repaired will have to be replaced.
5. If serious breakdowns have not occurred, then problems in the operation of the gearbox can be eliminated by changing the oil. If the liquid overheats regularly, while the cooling of the system is insufficient, the lubricant must be changed. Although Outlander CVTs are considered maintenance-free, they do require periodic oil changes.

User Alexander Stepanov in his video spoke about the problems in the operation of Mitsubishi Outlander CVTs.

Rules and terms of operation

Now let's analyze how much goes on average and .

Outlander transmissions can operate in several modes:

1. D. This mode is for moving forward. The position is considered essential. The transmission automatically changes the gear ratio based on the rpm of the power unit.
2. R. Reverse mode. Activation of this position is allowed after the vehicle has come to a complete stop.
3. N. Neutral mode. When the driver engages this position with the lever, the transmission is disengaged. Its activation is relevant for long-term parking or stopping. The neutral position can be used to start a car engine.
4. R. Parking. When the driver enters the parking mode, the driven shaft of the transmission unit is blocked by a special pin, which prevents arbitrary movement of the machine. Activation of the parking mode is allowed if the car is parked. To prevent accidental inclusion of parking, when the lever is in the appropriate position, you must press the brake pedal.

As for the service life, according to the official regulations, the variator serves as long as the entire life of the machine. This is 300 thousand kilometers. In fact, CVTs rarely work out such a resource. This is partly due to the quality of Russian roads, since CVTs are sensitive to regular use of cars on uneven surfaces. The service life of the transmission is also affected by errors made during use.

If the Mitsubishi Outlander is operated in off-road conditions, then the resource for using the CVT will decrease by 50%.

Find out about the symptoms of malfunctions in the operation of the CVT from the video filmed by the forwarder top channel.

The car owner should be aware that at low negative temperatures, the transmission needs to warm up. When starting the engine in the morning in winter, the engine warms up at low speeds. The gas pedal, until the internal combustion engine is heated, must not be pressed all the way. Keep in mind that the engine warms up faster than the transmission. For optimal heating of the box with the engine running, it is necessary to move the gearbox selector to positions D and R with the brake pedal depressed and linger in each mode for a few seconds. It is impossible to move sharply on an unheated transmission.

To increase the service life of the gearbox, you must adhere to certain rules:

• regularly check the volume of the lubricant;
• the oil change interval in the transmission depends on its condition, usually the fluid must be changed every 60-100 thousand kilometers on average;
• use the car less for off-road driving, avoid slipping;
• pay attention to the instrument panel - if the transmission emergency mode indicator appears on it, it is necessary to perform computer diagnostics and determine the cause of the malfunction in the gearbox;
• a car with a variator cannot be used to tow other cars, as well as trailers weighing more than 500 kg;
• do not allow the transmission to overheat, and if a corresponding indicator appears on the tidy, the car must be stopped and the cause determined;
• to prevent rapid wear of the structural elements of the gearbox, avoid aggressive driving, especially when the gearbox is not warmed up;
• with frequent use of the air conditioner, experts recommend installing an additional liquid cooling radiator.

The AnTiNooB Stream / Live channel in his video talked about the recommendations that will increase the life of the CVT.

CVT cooling in case of overheating

According to the reviews of the owners, one of the problems that appear in the operation of the variator is that the box is heated. To prevent critical overheating of the transmission, do not drive at high speed for a long time. Alternatively, you can additionally install a radiator device that will cool the unit more efficiently.

Selection and replacement of oil

In Mitsubishi Outlander transmissions, only original oil is allowed. The manufacturer has specially developed the DIA QUEEN CVTF-J1 product for CVTs of these cars.

Changing consumables in Outlander boxes is done as follows:

1. Start the engine of the car and warm it up to 70 degrees. The hotter the lubricant in the box, the more it will leave the system. The viscosity of warm oil is less than that of cold oil.
2. Drive the car into a garage with a hole.
3. Under the bottom of the vehicle, it is necessary to remove the crankcase protection by first unscrewing the two screws in front. The remaining bolts do not need to be unscrewed, it is enough to loosen them. The protection itself is pushed forward and dismantled.
4. Place a container under the drain plug, then unscrew it. Old grease will begin to come out of the transmission system. Assess her condition. If there are traces of deposits or wear products in the oil, then more detailed diagnostics and flushing of the system will be required. The presence of metal chips may indicate wear of bearing elements and other parts. If bearings fail, they must be replaced.
5. Screw in the drain plug.
6. Remove the dipstick from the level hole and fill it with fresh oil. The same volume that was drained is poured.
7. Start the car engine and warm it up. In turn, turn on all modes of the transmission selector. The lever must be in each position for at least half a minute. The process is repeated several times. This will allow fresh oil to pass through all channels of the system and mix with that part of the fluid that did not leave the gearbox. It is impossible to drain all the oil from the transmission at one time.
8. Stop the engine and drain the gearbox oil. So, you can partially flush the system.
9. Remove the bolts securing the pallet. When removing, be careful, some of the oil will come out of it. Assess the condition of the pallet. In the presence of wear products in the form of chips or deposits, it must be washed. For cleaning, a special agent or acetone is used.
10. Remove the transmission fluid filter. Rinse thoroughly and dry.
11. There is a gasket around the perimeter of the pallet. After removal, it will be damaged, so it must be changed. Get rid of the remnants of the sealant with a clerical knife. Install a new gasket, fixing it to the sealant layer.
12. Replace the filter device. If you removed the magnets from the pallet, then install them back. Put the pallet itself in place as well.
13. Replace the drain plug and fill the gearbox with fresh oil. The unit is filled with the volume of lubricant that was drained.
14. After that, the engine starts, the manipulation is repeated to turn on each mode for half a minute. The level of lubricant in the gearbox is checked through the dipstick. On a warmed-up unit, the volume of liquid in the box should correspond to the HOT mark.

The driver does not have to waste time switching from one driving mode to another. This simplifies the control of the machine.

Soft and smooth ride. Due to the absence of steps, the variator accelerates gently with increasing speed.

Fuel savings compared to classic automatic machines.

Cons of CVT transmissions:

1. Difficulty of operation. To prevent damage to the unit, the driver must take into account the requirements for using the car. Despite the fact that the Outlander model belongs to SUVs, its continuous off-road operation is not allowed.
2. CVT gearboxes are poorly rebuilt in urban operation.
3. The complexity of the repair. Structurally, the variator is a complex unit. In our country, there are not many specialists who can perform qualified gearbox repairs. Finding original spare parts is sometimes problematic.
4. If you turn to specialists for help, the cost of changing the lubricant will be high. And it is not so easy to accomplish this task yourself.
5. The high cost of repairs in general. Spare parts for CVT transmissions are expensive.

They overheat at high speed and are not viable outside of smooth asphalt! They fail even under non-critical loads!

Rumors about the dubious reliability of continuously variable transmissions (CVT) appear almost faster than the next new model with a CVT comes out. Moreover, they are born more often around all-wheel drive crossovers, the transmissions of which are the most loaded and often work at the limit of their capabilities - primarily on rough terrain. And these rumors are not unfounded: there are problems! As practice shows, they also happen in less offensive situations - even on urban asphalt.

That is why we brought three all-wheel drive crossovers together in diverse tests - the new Nissan Qashqai with a modernized transmission of the latest generation, the Subaru Forester and the updated Mitsubishi Outlander. And out of standings in our tests participated monoprivodnoy "Toyota-RAV4". Now you can buy one, and it is with a variator.

Talk about continuously variable transmissions overheating at high speeds has been heard by many more than once. The Za Rulem testers know this from their own experience: the overheating of the Outlander transmission in last year's test (ЗР, 2013, No. 7) prompted the idea to start these tests. Moreover, this time we took the updated Outlander, to which the manufacturer returned the variator radiator (at our insistence - see ZR, 2014, No. 8). It is clear that the radiator must provide the optimal temperature regime of the node and protect it from overheating. Did it help?

We checked the cars with a regime close to the limit and more typical for unlimited German autobahns. We have so few people who travel, and there is nowhere to travel like that, but the purity of the experiment is important to us! We drove 250 km along the high-speed ring of the polygon at an average speed of about 170 km/h. If the variators can withstand such a pace, then you can not worry about their health under normal operating conditions.

Winding circle after circle, we closely monitor the behavior of the machines. And ... we do not find anything interesting. Not a single car showed even a hint of transmission overheating - all worked without the slightest complaint. So there is no winner in this test. But more importantly, there are no losers either! So, the variator radiator implanted in the Outlander in these conditions copes with its task brilliantly.

1. You don’t have to worry about the transmission of the Outlander updated this year: it will withstand high speeds.

2. Forester with a 241-horsepower engine, of course, is able to go faster than its rivals, but we did not find any signs of transmission overheating.

3. Qashqai also passed the speed test without any complaints.

4. The front-wheel drive Toyota successfully passed the speed test in the same mode as the all-wheel drive rivals.

This test turned out to be the most difficult for cars. The height of the obstacle is 185 mm (this is not yet the highest curb among those that drivers are ready to storm). Task: climb it with the front and then the rear wheels, placing the car at a right angle to the "sidewalk". Then you need to repeat the exercise, but in reverse. You should, of course, drive in tight, because even the most ardent conquerors of the sidewalks will not dare to jump on such a high curb from acceleration.

Moving forward, "Subaru" overcame the obstacle without tension. And he refused to go back to the curb. Moreover, the electronics, protecting the transmission, simply does not allow the wheels to spin, and the engine forbids gaining momentum. How so? In the city, you can refuse such an assault and turn around one hundred and eighty, but what if such an “ambush” happens off-road? All in reverse - no way?

Mitsubishi did the same. Moreover, he refused to drive onto the curb in reverse even after turning on the Lock mode, which rigidly blocks the rear wheel drive clutch.

And then the photographer suddenly asked me to go to the curb again - again in the forward direction. The Outlander confidently jumped over the curb with its front wheels, but refused with its rear wheels, although not a single emergency lamp flashed on the instrument panel. It's just that the engine did not spin up over 1200 rpm, and the wheels stood still. We decided to wait ten minutes. And they guessed it: the car with a cold transmission, like the first time, jumped over the barrier with its rear wheels.

Qashqai turned out to be the most persistent. Moving forward, he easily passed the curb with both front and rear wheels - and just as confidently went back. But, having overcome the obstacle with the rear wheels, Qashqai stood up. Then there was not enough gunpowder: the front wheels do not spin, the engine refuses to gain momentum. Nevertheless, according to the number of exercises performed the first time, Qashqai is the leader in this test. Mitsubishi and Subaru tied for second and third places.

Let the curb and monoprivodnoy "Toyota". Having turned the wheels a little, she refused to overcome it both forward and reverse. It is logical - and for a front-wheel drive car, it is not at all ashamed.

5. "Mitsubishi" without a hitch passed the obstacle forward, but could not overcome it in reverse.

6. Moving forward, Subaru easily took the 185 mm curb, but refused to go back.

7. The winner of the test was Qashqai. He drove into an obstacle even in reverse - however, only with the rear wheels.

8. A front-wheel drive Toyota can't handle those obstacles.

At high speeds, we failed to overheat the variators. Let's try to do this in transitional modes, simulating frequent overtaking?

We make several accelerations in a row in the "pedal to the floor" mode - from 60 to 100 km/h and from 80 to 120 km/h. Not a single car showed signs of dissatisfaction: the acceleration time varies within the margin of error.

We complicate the task. After reaching 100 and 120 km / h - a sharp deceleration to 60 and 80 km / h, respectively. And immediately - a new acceleration, again in the "pedal to the floor" mode. Only after such a mockery did we manage to catch a certain thoughtfulness. After a sharp press on the gas pedal, the engines at first do not gain more than 2500 rpm and hold the car for a few moments. What are these moments? For "Mitsubishi" and "Toyota" - 0.2–0.3 s, in normal operation they are completely invisible. "Nissan" lost to itself 0.8-1.0 s. But the owner is unlikely to feel this “in everyday life”. Moreover, we received this data in an almost racing mode - with sharp acceleration and deceleration.

Nevertheless, according to formal criteria, we give the first place to Subaru, the second to Mitsubishi, and the third to Nissan. And the out-of-class Toyota in this test performed no worse than the second Mitsubishi.

Cars pass through the dry country road calmly. We climbed here mainly in order to test the cars on a steep but dry dirt-sandy slope. Cars did not compete in speed - too different engines. The task of testers is extremely simple: several times to get up and evaluate the behavior of transmissions. On all machines, they used the maximum of their capabilities: in Nissan they chose the Lock mode, in Mitsubishi they pressed the 4WD button, in Subaru - X-Mode.

All four-wheel drive cars drove up the hill confidently, without whims, which means that there are no losers or winners again. We did not find any signs of excessive stress or overheating of the transmissions.

The front-wheel drive Toyota didn’t drive up this hill - there wasn’t enough “hook”: if we put it in more toothy tires, it would overcome the climb, but it still can’t compete with all-wheel drive here.

Probably, ironing the site for hours, you can achieve dissatisfaction with the variators. But to imagine such a need for crossovers in real life is difficult. So, another draw.

1. The Outlander passed the Overtaking test with flying colours.

2. "Subaru" - the winner of the "Overtaking" test: overcame all the tests without the slightest criticism.

3. The biggest delay in the operation of the variator after a series of “racing” accelerations and decelerations is with Nissan, but it turned out to be scanty.

4. The thoughtfulness of the Toyota variator after several mocking accelerations and decelerations is minimal.

5. "Outlander" passed the test "Rise" without remarks.

6. The capabilities of the engine and transmission of the Forester are such that a steep climb can be overcome with little or no acceleration.

7. We did not find any signs of dissatisfaction with the Nissan transmission on a dry country road with steep ascents and descents.

8. Front-wheel drive "Toyota" did not take the rise, but had every right to do so.

SPIN-SPIN

To change the gear ratio in the variator, a multi-link steel belt is used that connects two sliding pulleys with conical surfaces. The belt consists of many plates fastened with steel bands. It contacts the tapered pulleys with the side surfaces of the plates, which have small, barely visible diagonal notches that improve grip. The simultaneous approach and divergence of the cones of the driving and driven pulleys changes the radii along which the belt moves. Accordingly, the gear ratio changes. This happens all the time, depending on the driving conditions. Therefore, the so-called gears of the variator are virtual. The variator includes a mechanism for selecting the direction of movement, two pairs of cones with a steel belt, a gearbox, a final drive with a differential, and control units.

On the Mitsubishi Outlander (the operation of its variator is shown in the diagrams), the most common variator, the Jatko-JF011E, is installed. Torque from the engine is transmitted through a torque converter (similar to those in automatic transmissions) to the direction selection mechanism, which contains a planetary gear and two sets of pressure plates - friction clutches. Depending on the direction of movement (forward or backward), the control unit sends a command to compress one of the disk packs. Further, through the belt, the moment is fed to a downshift. From it - to the main pair and to the drive wheels.

In the "neutral" mode - N - both packs of disks of the mechanism for changing the direction of movement are dissolved. The epicycle of the planetary gear rotates freely together with the drive shaft of the variator - no torque is transmitted to the drive pulley.

In parking mode - P - the situation is similar, only the locking mechanism is also activated, the latch of which engages with the ring gear of the driven pulley.

When the selector is moved to position D, one of the disc packs is compressed, connecting the epicycle to the sun gear mounted on the drive pulley, between the cones of which the belt is clamped. Further, the moment is transmitted through the belt to the driven pulley, from it to the reduction gear, the main gear - and to the wheels.

To drive in reverse (R), the front disc pack is unclenched and the rear disc pack is compressed accordingly. The carrier, on the axes of which the satellites, stops. The moment from the drive shaft goes to the epicycle, and from it to the satellite. The sun gear connected to the satellite rotates in the opposite direction due to the stop of the planet carrier. When reversing, the pulley radii remain in their original position. This is monitored by the control unit.

1. This year, the CVT radiator was returned to the updated Outlander. And they did it right!

2. The Forester variator does not have a radiator. However, we failed to overheat the transmission.

3. There is a variator radiator on Qashqai.

4. The CVT radiator on the RAV4 is combined with the cooling system radiator.

The Subaru Forester has a different variator - its own design. The TR580 model is installed on cars with atmospheric engines, and the TR690 model is installed in a pair of turbocharged engines. The fundamental difference from the Jatko variator is a different belt design (produced by the German company Luk). It also transmits the force by the end surfaces, but not by the plates, but by the pins connecting the belt links together.

The moment from the engine is transmitted through a torque converter, a reduction gear (a safety clutch is located in it), a drive pulley, a belt, a driven pulley, a second reduction gear, a mechanism for changing the direction of movement, a driven shaft. The safety clutch between the first reduction gear and the drive pulley is open when the engine is started, while the oil pump is not running. As soon as the pressure rises, the clutch is blocked. This is done to protect the belt from slipping during load surges when starting the engine.

On cars with a start-stop system, when the engine stalls at stops, the input shaft of the variator does not rotate, and therefore its oil pump does not work - the pressure in the system is low. So that at the next start of the engine it is high enough, the variator is equipped with an additional booster electric pump.

The scheme for transmitting torque from the engine is similar to that of Dzhatkovo, but there are some kinematic features. For layout reasons, the reduction gear is divided into two mechanisms - before the chain and after it. The mechanism for changing the direction of movement and switching to "neutral" is located after the pulleys, so they always rotate with the chain when the engine is running. The main gear is a conical hypoid, in a separate crankcase with its own lubrication system.

CVTs for Toyota are manufactured by Aisin. Structurally, they are similar to the Jatko CVTs. The belt also consists of plates connected with steel bands.

Nissans have Jatko CVTs. The new Qashqai received an improved model based on the JF011E. All components have been changed, even the transmission fluid is different. The range of gear ratios has been expanded, a different control algorithm has been applied.

LEGENDS AND FACTS

It was not possible to identify a clear winner in the sum of four tests. It seems that Nissan, which, we recall, has the latest version of the variator (this unit will soon be registered on other models of the Japanese brand), scored half a point more than Subaru. But after consulting, we decided to share the first and second places between these cars. After all, the fractions of a second lost by Nissan during intensive accelerations are fully compensated by good results in the Curb test. "Mitsubishi" lagged behind rivals quite a bit. In general, all cars performed very well and helped to dispel some myths about the unviability of CVTs. In normal, everyday use, continuously variable transmissions will not cause trouble. Of course, if you remember simple truths: crossovers, especially with a continuously variable transmission, are not SUVs at all! These are city and highway cars, allowing from time to time to overcome not very difficult obstacles. And it’s even more honest to call a monodrive one a station wagon with increased ground clearance.

Killing a continuously variable transmission is not easy. Wise electronics will protect the car from the driver, overestimating her and her abilities. Here they lived! But with many of today's drivers it's probably not the same.

"Nissan Qashqai" - 1st-2nd places

"Subaru Forester" - 1st-2nd places

"Mitsubishi Outlander" - 3rd place

Mitsubishi Outlander is equipped with both mechanics and automation, while a more economical and dynamic option is Mitsubishi Outlander automatic transmission. However, during operation, its main parts are subject to wear, which leads to the need to restore the box. This process begins with a thorough diagnosis. This is done using special equipment. Aulender is characterized by the use of CVT variators. They are characterized by good environmental performance, economy and smooth running. But their unreliability and constant failures constantly force us to turn to specialists. This is due to powerful, namely, the durability of the variator correlates with this indicator.

The design of the variator in a simplified format is presented in the form of two pulleys, with a belt thrown over them. This design provides a smooth change in gear ratio, which in turn allows you to achieve a smooth ride of the car. Weak point where most often occur mitsubishi outlander transmission problems, is a belt, more precisely, the materials from which it is made. In order for the variator to please the owner with long and trouble-free operation, during its operation, it is necessary to follow the instructions regarding its maintenance. Another disadvantage of this box is the presence of a short interval, which is necessary for maintenance.

To avoid frequent repairs, it is necessary to change the gear oil regularly, otherwise, oil starvation will inevitably lead to the wear of the teeth related to the planetary mechanism, which will turn the liners upside down.

Concerning Manual transmission Mitsubishi Outlander, then the most common faults here are:

• wear ,
• leak ,
• friction disc wear.

The main cause of failure is an untimely oil change, or the use of untested samples. Operating conditions also matter, for example, when shifting gears carelessly, when moving the car forward, shifting into reverse gear. Such actions significantly reduce the service life. This is due to design features, in particular, the input shaft is equipped with five forward and one reverse gears. The driving gears responsible for the forward drive are constantly engaged with the driven gears. Some of them are aligned with the shafts, while others are mounted on needle bearings that provide silent rotation. If the lever is neutral, the leading one does not transmit to the driven shaft. As long as the lever is in the neutral position, the gears can rotate freely.

They turn on the gears by moving the sliding synchronizer clutch, this leads to a rigid connection of the gears with the box shaft. For this purpose, each shaft is equipped with its own synchronizer. In order for the gears to mesh, their number of revolutions is equalized by means of synchronizers touching before the gears engage. Regardless of the type of box, whether it is a variator, mitsubishi outslander robotic gearbox or, it is necessary to carefully care for her during operation, mindful of her natural capriciousness.
