Automatic transmission - how to use? automatic transmission switching and control modes. Learning to control the "machine"

As a rule, often the cause of automatic transmission breakdowns is their illiterate maintenance and use. After starting the engine, in order for the automatic transmission to take working condition wait about a minute before starting to move. So let's move on to the topic of this article: driving with automatic transmission .

Automatic transmission control

P range (Park) - parking mode.

This mode is selected when the machine is parked for a long time. In this position, the controls are disabled in the box, the output shaft is blocked, as a result, the movement of the machine is impossible (the drive wheels are blocked, the blocking is not associated with the parking brake and is located inside the box itself). Starting the engine in this mode is allowed.

Do I need to use the parking brake while parking? On flat areas, subject to serviceability, blocking the output shaft of the box for secure fixation quite enough. When stopping on a slope, it is advisable to use the parking brake. In this case, first you need to pull hand brake, and only then put the gearshift lever in P mode. Thus, you remove additional load from the mechanism for blocking the output shaft of the automatic transmission.

Range N (Neutral) - neutral mode.

In this mode, controls are disabled. At the same time, with the output shaft blocking mechanism turned off, the car can move freely. Starting the engine in this mode is also allowed. N mode is used when towing a car for short distances, as well as for short stops.Sometimes some drivers have a question:

Do I need to translate the automatic (automatic transmission) into N at a traffic light?

It makes sense to transfer the automatic transmission to neutral mode only during long stops in traffic jams in hot weather, in order to avoid overheating of the automatic transmission itself. In other cases, this is not necessary at all.

Range R (Reverse) - reverse mode.

An attempt to turn on the R mode while moving forward will inevitably lead to a breakdown of the automatic gearbox and other transmission elements (on vehicles that do not have a corresponding lock in the transmissions, it is strictly contraindicated to turn on the R mode until it comes to a complete stop). It is also impossible to start the engine if the gear lever is in this position.
Four-speed automatic transmissions for forward movement have four modes: D, 3, 2 and 1 (L). It should be noted here that starting the engine is not possible if one of the listed modes is enabled.

Range D (Drive) - the main mode for moving forward.

This mode performs automatic sequential gear shifting (in this mode, all gears are usually involved, with the exception of upshifts). This mode is recommended under normal driving conditions.
Range 3(Number 3 on some types of automatic transmissions) - the first three gears are engaged while driving. This mode is active, it is great for urban traffic, it turns off when the ignition is turned off. Especially when high speed it will not work to save fuel, this mode does not allow the torque converter clutch to repeatedly lock-unlock in conditions of torn city driving (no more than 80 km.h.), It is also partially blocked by switching to higher gears. Most suitable for movement when unavoidable frequent stops and for driving on roads saturated with descents and ascents. Engine braking is possible in this mode.
Range 2(Number 2 on automatic transmission) - in this mode, only second and first gears are allowed. Most suitable for use in mountain winding roads. It is forbidden to switch to fourth and third gear.
Range 1(L or Low) - low gear. In this mode, movement is allowed only in first gear. The traction capabilities of the engine in this range are realized to the maximum, since the torque transmitted to the wheels only in first gear is maximum. Particularly effective engine braking in this mode. Movement on steep descents and climbs must be carried out in first gear.

Overdrive (O/D)

On some automatic transmissions, a mode is set in which it is possible automatic switching on overdrive. O/D button (Overdrive) used to connect this automatic transmission mode. Its recessed position when the mode (Drive) is on allows you to switch to a higher gear. If you release this button, then switching to last transmission becomes impossible again. The O/D OFF indicator indicates the status of the control system. If the indicator is on, then the use of the Overdrive mode is impossible, otherwise it is possible.

It is recommended to use overdrive mainly on the highway for a more economical and measured movement. Interestingly, some four-speed automatic transmissions (for example, (toyota) aisin 241e) can disable 4th gear with a gear ratio of 1, which is not an overdrive either!

One of the differences between the automatic gearbox and the mechanics is the inability to produce engine braking in each mode. In overrunning clutches, in modes that do not allow engine braking, the transmission slips and the car moves “coasting”. And when driver position 1 is selected, engine braking is activated from first gear. In the first gear in position D, such braking is not possible.

How to start the movement of a car with automatic transmission?

As a rule, often the cause of automatic transmission breakdowns is their illiterate maintenance and use. After starting the engine, so that the automatic shift boxthe gear has taken on a working state, before starting to move, you must wait about a minute. Before starting to move without pressing the throttle pedal, it is necessary to depress and hold the brake pedal while putting the gearshift lever in D or R mode. After waiting for a slight push, you can start moving by releasing the brake pedal and stepping on the accelerator pedal with your foot. Dynamic driving for some time after the start of movement should be avoided so that the oil in all nodes and assemblies reaches its operating temperature. Before starting to move, for more efficient warming up of the automatic transmission, the gearshift control lever handle must be moved to different positions, lingering in each of them for some time. Then, turning on one of the driving modes and pressing the brake, hold the car in place for a couple of minutes, the engine should be running at this timein idle mode. At low temperatures environment in position R, it is unacceptable to start moving without fully warming up the automatic gearbox, because this (due to the high viscosity of the fluid in the transmission) can damage the planetary mechanism.

Towing a car with automatic transmission

A faulty car is towed in N mode, but do not forget that it is possible only for relatively short distances. In view of the fact that in idle engine idle and oil pump, then the lubrication of the nodes and elements of the automatic transmission is significantly deteriorating. All of the above is relevant when transporting a car over long distances. Therefore, if it becomes necessary to transport your faulty vehicle having an automatic transmission, this must be done at a speed not exceeding 70 km.h. and at a distance of no more than 70 kilometers. Otherwise, it would be ideal to use a tow truck.

Is it possible to skid on an automatic transmission?

It is more difficult to stall on a car with an automatic transmission than on a car with a conventional “mechanics”. But if this nevertheless happened, then “rock” the car by switching the gearbox from the forward position to the position reverse gear and vice versa, is simply unacceptable. In this case, you need to use a lower range, it excludes shifting to higher gears, and in this mode, try to overcome the mud area using the brake as a clutch. In almost the same way (without re-gassing and playing along with the brake) they perform maneuvers in a limited space.

Is it possible to shift gears on the go?

Switching driving modes on the go is allowed, but not in all positions. So, for example, it is unacceptable to turn on the P and R modes when moving forward. The inclusion of these modes is carried out under the condition of a complete stop of the car. Neglect of this rule will inevitably lead to serious. It is also undesirable to put the gearshift lever in N mode while driving, because in this mode the connection between the engine and the wheels is disconnected and in case hard braking may cause the vehicle to skid. You can switch to any other automatic transmission mode on the move. In some cases, this is even necessary. For example, switching from mode 3 to mode 2 improves engine braking performance.

Additional modes of automatic transmission

In later model automatic transmissions, where there are more operating ranges, there are additional modes of operation. In the control system of the automatic transmission, they are present in the form of pushbutton switches. Experienced driver knows how to use automatic transmission modes, so let's look at everything ourselves.

Economy mode("Eco" or "E") - provides the minimum fuel consumption while driving, as the engine is limited in the speed range at each stage. Thus teamwork engine and automatic transmission passes in such a way that in each overdrive, the engine actually starts from idling further increasing them, but not bringing them to the maximum. In this mode, the movement of the car is calm and smooth.

Sports mode("S") - in this mode of operation of the automatic transmission, engine power is used to the maximum. Each subsequent gear is engaged at frequencies close to the maximum torque. Accelerating further, the rotation of the crankshaft reaches its maximum, and thereby the engine develops its full power and starts to work with full dedication. And the car in this mode moves with much greater acceleration compared to the economical mode. A special switch designed to implement a sport or economy mode is usually located next to the gear lever and may have various designations, such as - POWER, S, SPORT, AUTO, A/T MODE, etc. Sports automatic transmissions have also become widespread, which have slightly different transmission control algorithms. IN this case switching different modes work can be done both with a selector and with the help of the corresponding function buttons, when the position of the automatic transmission lever remains unchanged.

kickdown- a mode that allows the engine management system and automatic transmission to reach high values acceleration, for example, to overtake. The automatic transmission enters this mode after a sharp press on the accelerator pedal, switching to one or two downshifts. The torque transmitted from the engine to the wheels will increase, while the speed range in the engine is such that its return is almost maximum. And upon reaching maximum speed engine, the machine switches to the next overdrive. If the accelerator pedal is released, the automatic transmission will return to normal operation. Sometimes when off Overdrive mode Kickdown is not allowed. It is necessary to take into account the factor that on a slippery surface with a forced downshift, slipping of the drive wheels is inevitable and further emergence skid.

Winter mode(Snowflake) - to activate this mode, a special button or switch with the following designations is provided: Winter, W, Hold (or Snow). To avoid slipping of the drive wheels on a slippery road when starting off, the torque transmitted to the wheels from the engine is required to be minimal. This is done by starting the car from second or third gear - this is fraught with overheating of the automatic transmission, so driving constantly in this mode is contraindicated.

Emergency mode- this mode of operation of the automatic transmission is activated in case of malfunctions in the control system or transmission that can lead to. The control unit includes a transmission protection program and this allows the car to get to the car service on its own. As a rule, when emergency mode shifts are prohibited and any one gear is working. The number of such a gear usually corresponds to the gear in which the shift solenoids are in the off state. Also, when triggered, the torque converter lock is prohibited and is set maximum pressure in the main highway.

Adaptive automatic transmission mode (automatic transmission) | Automatic transmission adaptation.

Adaptive gearboxes owe their appearance to the progress in the development of electronic automatic transmissions. Control algorithms become more intelligent, hence new qualities appear in the same transmissions from the point of view of mechanics. Now the on-board computer monitors the features and driving style of the driver and adjusts the operation of the automatic transmission and engine properly for them. With a smooth manner of movement, the computer, by means of appropriate amendments, does not bring the engine to maximum power rates of operation, which significantly reduces fuel consumption. If the driver prefers a sharp, “gusty” driving style, accompanied by frequent depressing of the accelerator pedal, the computer emphasizes frequent acceleration and intense speed and brings the engine to maximum speed. In order to make the most dynamic acceleration the control system makes switching two, sometimes three steps lower. It is curious that the wear of the friction elements of an automatic transmission is already included in the operation algorithm. Which favorably affects not only the comfort of driving such a car, but also increases its efficiency and.

Automatic transmission mode AUTOSTICK (StepTronic, TipTronic)

Such an automatic transmission control system, in which both automatic and semi-automatic control modes are provided (the first was implemented by Porsche), here the switching command is given by the driver, and the control system ensures the quality of such switching. This mode, depending on the manufacturers, can be worn different names: AUTOSTICK, STEPTRONIC, TIPTRONIC. It is only available on vehicles with an electronic control system. automatic transmission gear shifting, and even then not at all.

What is TipTronic (Video)

The shift knob on vehicles with this system has special position at which the AUTOSTICK mode is enabled. This mode has two non-latching positions, labeled UP ,+, and DN ,-, required to switch to low or high gear. Gear selection in this mode is made by the driver manually, the selector lever is pushed in the direction, -, or, +, - shifting gears up or down. When the engine speed drops to idle, downshifting is automatically carried out only in the canonical design. Some manufacturers of transmissions automatically upshift at the maximum engine speed.

The mechanical part of such a box is indistinguishable from a conventional automatic box, only the control automation and the selector lever have been changed. Such automatic transmissions are characterized by a cutout for moving the selector lever in the form of the letter H, and the symbols, +, and, -,. Still, this mode (AUTOSTICK) is more semi-automatic than manual, since the transmission computer controls the driver's activity and will not allow him to select a gear that exceeds the permissible engine speeds or will not allow him to move from a higher gear. The rest gives the impression of using a manual gearbox. If such a desire arises, then you can easily return to the normal automatic transmission mode by putting the speed mode shift knob in position D, so it’s more likely riding on automatic transmission than "poking" with a pen.

On powerful modifications of cars, sports automatic transmissions are installed, which are equipped with a manual gearshift function. And this manual switching gears can be made not only by moving the selector up and down, but also with the help of small paddle shifters, pressing which allows you to lower or increase steps. This is quite popular in sports cars and executive sedans, which are equipped with powerful engines.

Before a novice motorist gets behind the wheel and gets driving skills in practice, it is necessary that the novice learn the rules traffic and basic technical disciplines regarding common device car.

More precisely, you need to know about the principles of operation of the main components that make up the car. Although the latter is not required to be studied according to regulations, this knowledge will not be superfluous for future motorists.

In this article, we will look at how to drive an automatic car for beginners, the principle of operation of the box - automatic, rules of use, switching modes of operation of an automatic box, etc.

Riding a car for beginners

So, the automatic transmission selector lever has several basic positions: P, R, N, D, D2 (or L), D3 or S. Let's consider each separately.

• The position of the gear lever in position "P" - park. Vehicle movement is not possible, while engine start is allowed in this mode.
• The position of the gear lever in position "R" - reverse. Reverse. This position must not be used while the vehicle is moving forward. It is not possible to start the engine in this mode.
• "N" - neutral. The car can move freely. In this mode, starting the engine is allowed, as well as towing the car.

  The position of the gear lever in the “D” position is drive (the main driving mode). This mode provides automatic shifting from first to fourth gear (recommended for use in normal driving modes).

• Shift lever position in position D3 (S) second low gear range (on roads with slight uphill and downhill slopes) or D2 (L) low gear range (off-road).

Not all automatic transmissions have such switching modes, it all depends on the modification of the transmission. Switching the lever from position D to position D2 or D3 and vice versa can be done while the vehicle is moving. Automatic transmissions can also be additionally equipped with gearshift modes: N - normal, E - economical, S - sports.

Car driving: automatic transmission

Having dealt with the principle of using automatic transmission, you can go directly to how to drive a machine for beginners. The first lesson in driving a vehicle should include the study proper fit driver driving a car.

• Driver's seat setup. The back of the driver's seat should have the most upright position, but not at the expense of the comfort of the driver. The removal of the pillow from the pedal assembly should be focused on the incomplete extension of the driver's leg when the brake pedal is pressed to the maximum.

After the position of the backrest of the driver's seat is adjusted in such a way that when the driver's back fully touches the backrest, his outstretched hand touched the top of the steering wheel with the pad of the palm of the thumb.

• Adjustment of rear-view mirrors. Once, the driver has configured driver's seat, you need to adjust the rear-view mirrors. As a rule, in modern cars two side and interior rear-view mirrors are installed (with the exception of pickups and commercial vehicles).

The mirrors must be adjusted in such a way that the driver, without changing his position and without turning his head, can instantly assess the situation behind the car in all mirrors only by moving his eyes.

With correctly adjusted side mirrors, 1/3 of the mirror should reflect the rear wing of the car, and 2/3 of the situation behind. With regards to interior mirror, it must be adjusted in such a way that top position cabin mirror tilt switch, it completely reflected the opening rear window car.

• After the driver's landing settings are completed, you can start the engine. Starting a car with an automatic transmission on many models is impossible without depressing the brake pedal in any position of the automatic transmission selector, except for P and N.

The key has four positions in the ignition lock:

1. Standard (basic position).
2. Withdrawal anti-theft lock(unlocking the steering column).
3. Switching on the ignition (control dashboard). Activated electronic system car.
4. Engine starting.

To start a car with automatic transmission:

• We insert the key into the ignition lock and depress the brake pedal, while the gear lever should be in the park "P" position or the neutral "N" position.
• Without releasing the brake pedal, turn the key in the ignition switch to the “Engine Start” position.
• Moving the gear selector lever to the “D” or “R” drive position, release the brake pedal, release the parking brake, after which the car starts moving.

It is important to remember that a car with automatic transmission is controlled by only one right foot, which presses either the gas or the brake. It is forbidden to press the brake with your left foot, and use your right foot for gas.

• Before starting the car, you need to make sure with the help of rear-view mirrors that there is no passing traffic, turn on the turn, move your right foot from the brake pedal to the gas pedal and start moving smoothly.

After leaving the roadway, all actions of the driver must obey the requirements of the traffic rules. The driver of the vehicle must comply speed mode traffic on this section of the road, keep to the extreme right lane, depending on road conditions and markup.

When driving in traffic, drive at the same speed as other road users, keeping the interval and distance from other vehicles. In cars equipped with automatic transmission, there is no need to change gears depending on the speed of the vehicle, which greatly facilitates driving and allows the driver to concentrate on the traffic situation.

• Uphill and downhill movement. Before climbing, the driver must assess the steepness, length and quality of the road surface laid on the rise. If the road surface good quality And weather allow to overcome the rise without slowing down, in this case, the driver of the vehicle, several tens of meters before the starting point of the ascent, making sure that his maneuver is safe, must depress the accelerator pedal in order to give the car maximum acceleration.

This maneuver is performed in order to increase the inertia of a moving vehicle in order to facilitate its entry into a hill without losing the vehicle's cruising speed.

If the road surface is of insufficient quality, or the weather conditions do not allow you to safely enter the “coasting” lift, the driver of the vehicle must take an extreme right position on the roadway. Next, at low speed, you should overcome the rise. If the steepness of the rise is too great, it is worth limiting yourself to downshifts on the automatic transmission (D3, 2, L).

When descending, the driver, on the contrary, must take his foot off the accelerator pedal and coast down. At the same time, the brake pedal must be used to regulate the speed of the car, adhering, as in all cases, to extremely right side roadway.

• Reverse movement. Before starting to reverse, the driver of the vehicle must first make sure that there is enough space on the carriageway behind the vehicle to perform the maneuver.

After that, on the rear-view mirrors and by turning the head, the driver of the vehicle must make sure that there are no vehicles or other obstacles in the direction of his car.

After making sure that there are no obstacles, the driver moves the automatic transmission selector to the “R” position, removes his foot from the brake pedal and, carefully dosing the thrust with the accelerator pedal, performs the maneuver. If the traffic is intense, then to ensure more security when maneuvering, the driver of the vehicle can additionally turn on emergency lights.

• Neutral position "N". This position of the automatic transmission selector is used extremely rarely, often for “service” purposes: to roll the car onto a tow truck or on a lift, as part of maintenance, etc.

In some cases, "neutral" is turned on if necessary to move the car a few meters with the engine off. When driving in traffic, it is not recommended to move the automatic transmission selector to position N, as this “disconnects” the engine from the automatic transmission, which leads to a complete loss of traction on the drive wheels and can cause emergencies.

What is the result

As you can see, driving an automatic car, especially for beginners, is much easier compared to driving a car on. A car with an automatic transmission is ideal for driving in city traffic, since the driver, while driving a car with an automatic transmission, is not distracted by gear changes.

We also note that relatively recently on the territory of the Russian Federation it became possible to obtain driver license, in which it is separately noted, that is, it is impossible to drive a car with a manual transmission with such a driver's license.

Finally, we add that riding a machine for beginners has its own rules that must be observed. Following such rules and recommendations allows, on the one hand, to save yourself, and on the other, to avoid accidents on the road.

Driving a car with automatic transmission: how to use the box - automatic, automatic transmission modes, rules for using this transmission, tips.

Automatic transmission differs from manual transmission in simple control and does not require additional skills or abilities from the driver. Even a child can successfully handle driving a car on the machine. The operation of an automatic transmission has its own characteristics.

The automatic transmission selector is the main control of an automatic transmission. On the automatic transmission selector, as a rule, the following designations are located:

P - Parking mode. The box is blocked.

N - Neutral, the wheels of the car are not blocked, the moment from the engine is not supplied to them.

D(D3) - Normal forward movement with all gears shifted sequentially.

S(L2,2,D2) – Mode low gear. IN extreme conditions This is a forced gear reset and engine braking. If winter mode is not provided, then S will be its analogue.

L (D1) - Movement only in first gear. It is impossible to drive in this gear for a long time and even more so quickly. The gearbox and motor will quickly overheat, fail and repair will be necessary.

Overdrive - Prohibition of switching the next gear. Needed for overtaking.

Power / Sport - Automatic transmission mode, when the gears are switched to more high revs engine.

ECO - Economy mode.

Winter/Snow - Driving mode on slippery surfaces (sand, snow, ice), the car will start from 2-3 gears, making it easier to overcome obstacles. This is especially true for winter conditions.

Block - Unlock button (may be in the form of a key) for shifting gears without a key in the ignition. Necessary for towing a car after an accident or breakdown.

Kick-down - Operating mode for fast acceleration. The gas pedal is pressed all the way, the machine "thinks" for 1-2 seconds and starts to accelerate the car sharply.

After buying a car, it is better to study its owner's manual. The machine seriously makes life easier for any car owner, but is not able to correct all his mistakes. For correct driving, you still need experience and understanding of the operation of the car.

How to drive a car with an automatic transmission?

1. Before traveling, especially in winter period Be sure to let the car warm up. The oil should be distributed throughout the automatic transmission. Some manufacturers advise you to stand in gear for a few minutes (on the brake, of course). If this requirement is not observed, the box will break and repair will be required.
2. It is not recommended to leave the car on the rise only in the parking lot, you must use the handbrake. In position P, the box is locked mechanically, but the lock is not designed for loads. If the car somehow starts moving in this position of the automatic transmission selector, it will be damaged.
3. The rear and front change only when the car stops, but at the same time holding the lever in the N position is highly discouraged.
4. Start moving only after a characteristic push into gear.
5. Accelerate and move off as smoothly as possible. The wear of automatic transmission mechanisms depends on this.
6. It is not recommended to move the lever to the N position during short stops at traffic lights, as well as when driving downhill. Experience shows that shifting gears at speed quickly disables the automatic transmission.

1. When driving on slippery surfaces (rain, snow, ice, sand), it is necessary to move as smoothly as possible without slipping. If the car is still stuck, it is absolutely impossible to slip - the box can die right on the spot. There is a huge amount of advice and ways to overcome obstacles. Get used to driving smoothly in winter conditions.
2. Periodically check the condition and level of the oil. Old oil loses its properties and can no longer provide a box normal conditions work.
3. When overtaking, use the overdrive mode.
4. If something is wrong with the box, you need to immediately transport it to the service and repair it. Riding on faulty automatic transmission will only make the situation worse.
5. The engine can only be started in positions N and P.
6. If you need to move quickly, and the machine “dulls”, hold the gas and brake pedals for 1–2 seconds before starting to move, then release the brake sharply.
7. It is not recommended to transport cars using automatic transmission. In extreme cases this can be done very slowly and only in the lowest gear (L).
8. Use only the oil recommended by the manufacturer. If the oil has other properties, the automatic transmission will fail and repair will be necessary. To understand which brand is needed, the instruction manual will help.

automatic transmission and winter

Automatic transmission operating modes in winter have their own characteristics. Most automatic transmission failures occur in winter, so it is very important to follow the recommendations for operating a car in the cold season:

1. In winter, there is a lot of snow, which leads to frequent slippage of the car. This should be avoided.
2. It is important to warm up the box in winter, immediately after the engine has warmed up.
3. If the automatic transmission oil has not changed for more than 30 thousand kilometers, it is worth replacing it. It is especially important to do this before operating the car in winter.
4. It is necessary to switch the box to the “movement in winter” mode, if there is one in the car. It is usually denoted by the following characters: WINTER, SNOW, "*", HOLD.

Taking into account the peculiarities of driving a car in winter and observing the rules of operation, the car owner will save himself from many problems that are typical for this time of year.

Operation of popular car brands with automatic transmission

Ford Focus

The transmission of a Ford Focus car is as reliable and durable as other parts of this brand. Experts consider Ford transmissions to be among the most trouble-free and stable, in addition, their repair is quite simple and cheap.

Incorrect and careless operation, non-compliance with the recommendations of the Ford car manufacturer can lead to premature failure or even permanent failure of the Ford Focus automatic transmission, with the need for it complete replacement. To avoid such unpleasant consequences, do not neglect the simplest rules for using an automatic transmission in a Ford Focus car and the recommended ways to care for it.

By the way, these rules are quite simple:

• try to avoid abrupt start and braking, slippage of the car Ford Focus;
• be sure to warm up the Ford Focus before starting the trip;
• shift the selector correctly and smoothly, avoid using kick-down (forced downshifting);
• monitor the oil level in the automatic transmission, change it in time; You can find out the replacement period for an automatic transmission model by looking at the instruction manual.
• replace from time to time Consumables car Ford Focus: filters, gaskets, oil seals.

If you follow these simple tricks, you can extend the operating period of the automatic transmission of a Ford Focus car several times over, as well as use its full potential.

Lada Granta

Lada Granta is the first car domestic manufacturer, on which an automatic transmission was installed, which was a real breakthrough in the engineering industry of our country. The first Lada Grant with such a gearbox was released in 2012. Automatic transmission for cars Lada Granta supplies Japanese firm JATCO. Transmissions of this brand are mounted on cars of such famous brands like Toyota, Nissan, Volkswagen, Mazda and Subaru. Adaptation Japanese automatic transmission with an engine manufactured in Togliatti was not easy for manufacturers, in connection with this, the engineers decided to turn to their Austrian colleagues for help. As a result of these combinations, many functions of the automatic transmission from Japan had to be abandoned, but, ultimately, the Asian automatic transmission was combined with domestic motor still succeeded.

There is no doubt about the reliability of the automatic transmission of the Lada Grant car, Russian manufacturers really managed to release quality car, permanent repair which is not required. Numerous test drives and positive reviews car owners of the car brand Lada Granta confirm this information. But, as in any other car, when operating an automatic transmission in a Grant, you must follow some rules:

• monitor the oil level in the automatic transmission and its condition, change filters and seals in time; What filters to use and what brand of oil is needed can be found by looking at the instruction manual;
• press the gas pedal smoothly, try to avoid slipping;
• V very coldy, it is worth warming up the car for 10-20 minutes;
• when transporting, it is important to fix the drive wheels above the ground to avoid their rotation;
• you can’t drive a Lada Grant car when its engine is faulty, press the “gas” and “brake” pedals at the same time, and shift the gear to the “forward” or “reverse” mode until the car’s movement is completely stopped;
• at reversing by car Lada Granta is not recommended to switch to great speed movement;
• if the automatic transmission oil has become black or Brown, it should be replaced immediately and the operation of the automatic transmission of the Lada Granta car should be diagnosed.

Toyota Camry

The body of the Toyota Camry 30 is equipped with a box U241E. This is a reinforced gearbox designed to work on 2 and 3 liter engines. Camry 30 in all respects reliable and unpretentious car, this also applies to the box. The power reserve for a 30 body is quite solid, which allows the automatic transmission to be operated in quite extreme conditions and for a long time transfer big moment without consequences. Compared to U240, 41 models have reinforced drums, axles and pump. For proper operation of the Camry 30, you will need to monitor the level and condition of the oil, like any automatic transmission, the U241E is sensitive to oil starvation. Having a reliable Camry 30 at their disposal, drivers often simply forget about periodic maintenance, assuming that this car must first drive its first million. This is wrong. Camry 30 will travel more than 1,000,000 only with proper operation. Also on the 30th body you can find automatic transmissions U250, U141, U151. On 30 models with a 2AZ engine, a 5-speed U250 was installed.

Honda

Owners of the Honda Civic, Element, Pilot, Stream should remember that the automatic transmission does not have an additional cooling radiator and the box should be operated very carefully. Modern Honda automatic transmissions, for example, the Accord body, starting with the CL7, are equipped with additional mode M, responsible for manual gear shifting. D3 - mode for difficult conditions operation Honda: city traffic jams, trailer, rough terrain.

Audi 8, BMW 3,5,6 and Volkswagen Phaeton

Automatic transmission 09L is installed on premium cars audi 8, BMW 3,5,6 series (except for the 7 series, a 5-speed body is still installed on the 740) and Volkswagen Phaeton . 09L has 6 stages and is designed for engines up to 3.5 liters. Due to the number of gears in the 09L, fuel economy is seriously affected, in addition, the 09L is a very reliable and unpretentious gearbox. For correct operation, the 09L requires frequent replacement main filter element, single layer membrane. If it is not changed, this will lead to oil starvation and the 09l will quickly fail and need repair.

Mercedes

Brand Mercedes Benz independently develops and manufactures gearboxes for its cars, which is why the characteristics of this unit have reliable and durable parameters. The operation of the automatic transmission of Mercedes cars is particularly smooth, which fully coincides with the ideology of the design of cars of this brand as a whole. Most models of the Mercedes Benz brand have a gearbox - a variator type.

A variator is a device in an automatic transmission that transmits torque, which is aimed at smoothly changing the gear ratio in a certain control range. In other words, the CVT is needed for stepless motion, which imparts smooth rotation to the drive wheels. Thus, a Mercedes with a CVT-type gearbox starts its movement more smoothly, and picks up speed without dips and jerks. Acceleration at the same time occurs more rapidly due to the lack of gear shifting.

Also, the owner of a Mercedes car with a CVT-type automatic transmission will never have to experience such unpleasant moments as a car stalling at a traffic light or rolling back when driving uphill. Some motorists may be alerted by the absolutely identical sound of the engine, regardless of the speed and mode in which it operates, but apart from the lack of aesthetic pleasure from the sporty "roar" of the engine, this does not bear any negative consequences, and has no effect on dynamic properties Mercedes car.

The variator box has several significant operational differences that owners of a Mercedes car should consider:

1. Pour into the variator special liquid, which differs from the usual oil required for automatic transmissions. In addition, careful monitoring of the level of this fluid in the gearbox is required.
2. Heavy loads on the car in cold weather should be avoided. Before driving, be sure to warm up the car.
3. The operation of the variator box directly depends on the health of the pressure sensors, speed, crankshaft position. In the event that at least one of them fails, the use of a Mercedes car will have very detrimental consequences, including wrong work transmission. Therefore, it is very important to monitor the car's sensors, make them visual inspection before each movement.
4. And most importantly, if a variator box malfunctions, it cannot be repaired on its own. It is necessary to repair the variator and replace it only with specialists in the salon according to maintenance cars. The repair of the variator has not been mastered in Russia to the proper extent, you should remember this and not subject the gearbox to unnecessary loads.
5. Study the manual for a car with a CVT and do not make mistakes.

Now many newly minted motorists decide for themselves which car to choose. The most, perhaps, important criterion it's the choice of transmission - and as sales statistics tell us - automatic transmission is growing exponentially. It is understandable in the city is very convenient. However, on many automatic transmissions, there is a so-called “manual mode” when you change gears in a physical way, usually this is a plus and minus on the lever (made with a button like mine) or shifting the gear lever. BUT WHY is there a manual mode on the machine? Are we taking a fully automated process? Today will figure out...

To be honest, such a solution is correctly implemented - only on torque converters and on robots, that is, you physically shift gears, for example, such a solution is also present on the variator, but there it is a purely software feature, because the variator gearbox is stepless, that is, it has no physical transfers.

Oh well, in general - there is a presence on almost any automatic transmission, but for what ??? Such mechanical mode many are brain-teasing — it seems to be moving away from mechanics, but it is here again, it turns out “rubbish”!

It absolutely does not require special skills, it turns on - elementary. Personally, on my machine, it’s enough to move the lever to the “M” position, you will see a speed gradation on the instrument panel, “M1”, “M2”, “M3”, etc., for example, I have six steps, which means top gear "M6".

As for switching - you can do it as from a parking lot, that is, start off in manual control, or already at speed, transfer the box to mechanics and adjust as needed! It can be done this way and that, no matter, for the automatic transmission it does no harm.

Why is this mode useful?

To be honest, some time ago, there were no such manual modes! In 85% of cases, a simple driver does not experience any discomfort from this, you quickly get used to the machine and adapt, then you don’t even notice how it works. However, the mechanical mode is often simply necessary, one cannot do without it, let's list:

• Wheel slip or off-road.
• Slide.
• Speed.
• Gear braking and cornering.
• Traffic jams.

Yes, yes, you heard right for these points and the manual mode is important, that is, it gives you more possibilities than the "brain" of the machine. Of course, it is possible to pass all these obstacles on the automatic transmission, but some points are simply unsolvable for him, as we say the first one. Let's go into more detail.

Slipping or off-road

IN our snowy homeland - oh, how necessary. If you do not put the automatic transmission in manual mode, then as the speed increases, it will try to shift to a higher gear, thereby “choking” itself. I myself personally encountered this, for example, you start to slip, the car seems to make its way through the snow a little - and it bangs into the second or third, there are not enough revolutions and the car gets up. This is where the mechanical mode helps, turned on strictly the first one and “fights” snowdrifts (drifts will be in the video below).

The situation is absolutely the same with mud, because in fact the movements in these two environments do not differ, and here and there we skid, the gears that we have chosen are important to us, that is, we think for ourselves.

Slide

Here, manual control is also pleasing - when driving from a protracted hill, you ease the pressure on the gas pedal, the machine will try to switch to a lower gear after some time, which will indirectly stop the car! You can manually leave the overdrive until the hill is completed. Thus, you save fuel, because turn on.

Speed

Not always modern machines, smart. That is, the pressure on the gas pedal is not always adequately perceived. What if you need to accelerate sharply, and the automatic transmission does not understand this, of course, now almost everyone has KIK DOWN, they pressed the pedal to the floor and the engine quickly “spun up”! But here's what to do - if you need to get around a large truck or trucks, and you need to leave the overdrive for a long time? This is where the manual mode will help, just “lower” to desired gear, at speed, let's say it is “5” or even “4”, and we press “gas to the floor”, after driving around the trucks, we switch to auto mode.

Gear braking and cornering

• A controversial plus, but it’s worth noting - if you want, this came to us from the “mechanics” when you switched from high to low and stop the car - say on slippery roads. After all, the wheels are not blocked, braking is more effective. On the machine, now you can also do this, for example, you drive in 6th gear - there are obstacles in front, in the distance, and the road is icy, the car does not adequately behave when you press the gas pedal. Just mechanically downshift and the car will get up, slowly and confidently, then bring it to a complete stop with the brake pedal. As I said, this method is controversial, because now there are a lot of sensors and systems (ABS, EBD, ESP, etc.) that will help stop the car without the participation of the box, but God saves the safe.

• This is cornering if you go on high speed, then it is worth transferring to a lower gear manually, and you no longer need to use the brake, the speed drops, the turn is completed.

As you understand, this item, nevertheless, is for lovers of freedom of action who are experimenting with the "automatic" at speeds.

Traffic jams

Also a controversial point, but I met on many forums.

Many people use manual mode for driving in traffic jams. "How?" - you ask. Yes, simply, the machine will always jump from first to second, respectively, fuel consumption will increase. In order to somehow reduce it, you can choose a “pure” second gear and use it to overcome the traffic jam! However, it is worth noting that acceleration should not be sharp, yet second gear is not for starting a car.

In fact, these are all advantages. manual mode automatic transmission, I personally noted for myself and constantly use it - when slipping and when driving downhill, the rest is not so important!

Now watch the video lesson.

This concludes, read our AUTOBLOG, there will be much more useful.

Use of various technologies modern automotive industry makes driving much more comfortable. With the help of sensors, sensors and sensitive devices, we can completely forget about the complexities of driving a car, but only if the budget allows us to buy a car equipped with all these devices. For a regular budget, one common comfort feature is available today - an automatic transmission. This is an important plus for any car and really getting the desired comfort.

But driving a car with automatic transmission should be with certain features. An automatic transmission is a fairly gentle unit in your car, so it requires fairly gentle operation. Otherwise, you will often have to visit service stations and order services. professional repair. It is cheaper and easier to learn how to properly manage an automatic transmission and forget about problems with the unit.

The main mistakes in the management of any type of automatic transmission

Automatic transmission requires certain driving skills. If we are talking about a traditional automatic transmission, you need to start more smoothly and give the car more time to accelerate. In the case of DSG or PowerShift robotic nodes, on the contrary, it is better to start aggressively, and when desired speed reduce your ardor to dynamics.

The question of the correct operation of an automatic transmission is quite important point not only because of the change in fuel consumption readings. In this case, it is necessary to maintain the performance of the box and avoid costly repairs. It is important to understand that it is the checkpoint that mediates between your actions and power unit. General rules for the operation of most machines are as follows:

• it is better to give preference to a smooth ride, sparing all the delicate components of the gearbox assembly;
• acceleration can be intense, but should not be abrupt, especially when overtaking and sudden acceleration;
• a trip along a mountain road should be careful, because it is impossible to brake with an engine on an automatic transmission;
• you can tow the machine, but you should follow the manufacturer's special recommendations;
• it is impossible to start a car on an automatic transmission from a pusher, this can only break the box;
• an untimely oil change in the box can be a problem that will necessitate a major overhaul.

It is also worth remembering that the repair of any machine is very expensive, therefore it is better to maintain the equipment well and avoid trouble with repairs. If you have a car with stepless variator, remember that such boxes are actually beyond repair. Often, after serious breakdowns, they are completely replaced.

Also modern robotic boxes, which are present in the arsenal of every major global brand, are very poorly adapted to repair. Therefore, in the presence of the first malfunctions, you should immediately contact service center and fix problems. Serious breakdown may result in a very costly replacement of the unit.

Automatic transmission control algorithm

Driving a car with automatic transmission may seem easy enough, but many drivers make a lot of annoying mistakes that lead to trouble. For example, we can recall the problem of many drivers who have switched from manual to automatic. This is a constant switching off of the transmission at a traffic light and its inclusion at a permissive signal.

Turning off the gear on the machine, if you are going to move in a few seconds, is not worth it. This will only increase the wear of the unit. Imagine how much longer the equipment will last, which is not forced to turn off at every traffic light. To properly control the machine on the machine, use the following algorithm of actions:

• get in the car, get ready for the trip, make sure that the parking brake is in the active position;
• move the gearbox selector to position P (most likely, it is already in this position);
• press the brake, in case you forgot to turn on the handbrake, turn on the ignition of the car and after loading on-board computer start the car;
• let all the units warm up well and technical liquids- one or two minutes is often enough for this;
• move the gearbox selector to position D or R - depending on the direction of your movement (forward or backward);
• remove the car from parking brake and gently release the brake pedal under your right foot;
• do not use your left foot to drive an automatic transmission vehicle;
• after fully releasing the brake pedal, the car will move, it can be controlled by gas injection or braking;
• when parking the car, stop, hold the brake pedal with your foot, shift the gearshift lever to position P and turn off the car by applying the handbrake.

As you move, switching off and on the transfer is not necessary. This will only allow you to wear out the parts of the gearbox faster and soon end up in the repair shop with the next problems. So it's better to use the proven simple way to drive a car on the machine. And the rest of the understanding will come to you as soon as your own experience is enough.

Also remember that each car has its own type of automatic transmission. When changing the car, it is worth getting used to the offered features of the car and getting more information about the behavior of cars on the road. Such data will help you avoid unpleasant situations while driving. You also need to get used to the car when changing the car on the mechanics to a car with automatic transmission. We do not recommend teaching your relatives how to drive automatically in their car, as the hero of the following video does:

Summing up

Driving an automatic car is much easier than driving a car with mechanical box gears. You don't need to think about the number of turns, gear ratio And normal mode trips. All that is required of the driver is to press the gas or brake pedal to the extent that you want to get a response. Getting used to this feature of the trip is very simple, but it gives a feeling of complete freedom.

Do not forget that the working conditions of quite expensive and delicate equipment depend on your pressing the pedals and levers. It should always be remembered that the quality work of the car is connected precisely with proper operation.
