So, some very important tips are offered that the owners of those cars on which there is an automatic transmission should understand and follow.
1. Do not use kick-down in your automatic transmission. If a person is not the owner of a sports car on which xenon is installed, but on the contrary, there is an ordinary car in his garage, but he does not like to drive on the roads with a “breeze”, then he should refuse such a box. It's no secret that at high speeds, the oil in the box begins to warm up to a very high temperature, and the clutches begin to wear out several times faster.
2. Timely oil change in automatic transmission. We remind you that in any service book for such a box it is written that every 60,000 oil in the box should be changed. Or every 2 years. I must say that the oil in the gearbox must be of high quality, because the gearbox is very sensitive to this oil parameter. But over time, the oil gradually begins to lose its performance properties. And it’s better to change the oil in the box in a timely manner than to repair the automatic transmission itself later.
3. Fill in the automatic transmission only with oil that is intended only for a box of this type. There should be no substitutes. And just a name like AFT is not enough. Therefore, oil manufacturers are beginning to impose additional requirements on their products that exceed the standard generally accepted quality classes.
4. If the car stopped at a traffic light, or got stuck in a traffic jam, then you should not switch the automatic transmission to the “neutral” or “parking” mode. For if the car stands idle for a couple of minutes in the “drive” mode, then less harm will be done to the box than when making multiple switches.
5. In winter, the automatic transmission should be warmed up. And it is necessary to warm up, regardless of the oil poured into the box or its model. For what, start the engine, and without releasing the brake pedal turn on the "drive" for 2-3 minutes. For a couple more minutes, turn on the "reverse". As a rule, this turns out to be quite sufficient to warm up the box in ten-degree frost.
6. Always put the car on the handbrake. Those. whether the car is downhill or not, it will be much safer for the box if its engines are started and turned off in this way:
To stop the engine: completely stop the car and without removing your foot from the brake pedal, put the automatic transmission in the “parking” mode. Also, with the brake pedal depressed, apply the hand brake. Now you can turn off the engine.
To start the engine: press the brake, start the engine, with the brake pressed, turn on the "drive" or "reverse" mode, remove the handbrake and release the brake.

HOW TO “EXTEND THE LIFE” OF AN AUTOMATIC TRANSMISSION
Our modern understanding of the world is based on the achievements of courageous people who are not afraid of severe trials and death. Researchers of the Middle Ages were ready to risk a lot by undertaking expeditions to harsh places that were not open to the village. History is replete with examples of such courage, however, the names of very few travelers remain on its indestructible tablets. Before you are several undeservedly forgotten expeditions, each of which seriously changed the picture of the world.
Australia Luis Vaez de Torres
A Spanish squadron of three ships set off in search of the mysterious Australia in 1605. The commander of one of the frigates was Luis Vaes de Torres, who fought off the main group during a storm. Quite by accident, the navigator stumbled upon New Guinea and mistook it for Australia - and yet she was just across the strait. Torres ended his days in Manila, firmly convinced that he had indeed discovered a new mysterious continent.
Bougainville circumnavigation
Louis Antoine de Bougainville was an 18th century French admiral. He rose to prominence as a result of fighting in the Seven Years' War and the American Revolutionary War. After the wars, Bougainville decided to become the first Frenchman to circumnavigate the world. Taking command of two ships with a crew of 330 people, this active citizen was indeed able to circumnavigate the globe, completing his journey in Bougainville in 1769.
Arabian tale by Carsten Niebuhr
Carsten Niebuhr became famous as a traveler in the Arab countries, capturing in his diaries the most important data for that time about unexplored places. A mathematician and naturalist, Niebuhr was very attentive to his work, which allowed scientists to draw the right conclusions about distant Arab countries. Of all the members of the Arab expedition, only one Niebuhr survived.
Search expedition of James Clark Ross
This Scotsman, a descendant of several generations of sailors, made one of the first expeditions to Antarctica - and even found it. However, Ross mistook the newly discovered territories for islands and did not land on them. He also discovered the largest Antarctic volcanoes Erebus and Terror, but could not find the missing expedition of John Franklin. The affairs of the great navigator were undeservedly forgotten by everyone except professional historians.
Alexander Mackenzie transcontinental expedition
Alexander Mackenzie is remembered as a great explorer in Canada and his native Scotland, but he never received the worldwide recognition he deserved. Unlike their contemporaries, Lewis and Clark, who went on an expedition to explore new American territories. Their transcontinental journey ended in 1806, but Mackenzie made the same journey almost ten years earlier. His group went to the Pacific coast, and the traveler not chasing fame left a simple inscription on the stone - "Alex Mackenzie from Canada, by land, July 22, 1793."

How to extend the life of the automatic transmission
When choosing a car, many drivers choose between automatic transmission and mechanics. Some people prefer a manual transmission only because, according to their understanding, an automatic transmission is less reliable and breaks more often than a mechanical one. Actually, this is a delusion. With proper operation and quality and regular maintenance, it is possible to extend the life of an automatic transmission, which can surpass a manual one.
So, to extend the life of an automatic transmission, you need to be guided by certain rules:
1. Moderate riding. At high speeds, the oil temperature increases significantly. This leads to rapid wear of the box. That is why you should not turn your car with automatic transmission into a racing car. In such cases, moderate driving should be used. This also affects the amount of fuel consumed, which is much less consumed with smooth braking and not too high speed. Moreover, such driving provides maximum safety on the road.
2. Timely change the oil in the box. The oil change time is clearly stated in the service book. An automatic machine, unlike mechanics, is much more sensitive to the quality of the oil present, which loses its original properties with every kilometer run.
3. As a rule, the original oil is used for automatic transmission, which is specified by the manufacturer. If it is written to use a specific oil, only that oil should be used.
4. In the urban cycle, while standing in a traffic jam or at a traffic light, you should not switch the box to other modes (parking or at neutral speed). In cases of a short stop, you need not to switch anything and remain in the same “drive” mode. From this harm is ten times less than constantly switching automatic transmission.
5. In frosty weather, the car must be warmed up. To do this, after starting the car, turn on the "drive" mode, holding the brake for a few minutes. After that, turn on “reverse” for a park of minutes. Five minutes of such warming up is enough at an air temperature of -10.
6. It is necessary to turn off and start the car on the machine according to a certain algorithm:
At a full stop - stop without removing your foot from the brake pedal, set the parking mode, tighten the hand brake, turn off the engine, release the brake;
When starting - press the brake pedal, start the car, set the desired mode, remove the handbrake and only then release the brake.

Many drivers of cars with a manual transmission have probably encountered such a phenomenon as fuzzy gear shifting, howling noise when driving, spontaneous jumping out of the engaged gear, or even a complete stop of the car. All these are signs of failure of the gearbox, which is a rather complex and expensive unit. It turns out that most of these failures can be avoided. To do this, you must properly operate the gearbox of your car.
One of the main conditions is the timely replacement of the gear oil filled in the gearbox. The oil must be approved by the vehicle manufacturer.
Take a short break every time you change gears. When shifting gears from top to bottom, do a re-gas - this will greatly extend the life of the synchronizers.
When reducing the speed of movement, shift to a lower gear, preventing the car from moving under tension. The specified mode creates shock loads on the transmission parts, shortening the service life of the latter.
When starting downhill, start in second gear and then immediately shift to fourth gear. This reduces wear on the gearshift mechanism. The same technique can be used when the car is slipping, which also causes increased loads on the transmission.
Switch from winter tires to summer tires and vice versa in a timely manner. Check tire pressure regularly.
Try to avoid towing other vehicles - this significantly reduces the resource of the entire vehicle.
Do not load the car in excess of the amount provided by the manufacturer.
You should periodically check the level of gear oil filled in the gearbox. Add oil if necessary. Checking the oil level filled in the gearbox should be done in a cold state. Overflowing oil can damage the sealing glands.
If oil leaks from the gearbox, repair the leak immediately. Otherwise, moisture or dirt may get into the gearbox, which will cause increased wear of the gearbox parts.

How to extend the life of the automatic transmission?
There is a misconception among motorists that an automatic transmission is less reliable and durable than a mechanic. This is wrong. Or rather, not quite so. An automatic transmission is simply more demanding on the quality of service and operating conditions, respectively, if the automatic transmission is serviced correctly and on time, as well as properly operated, an automatic transmission can last no less, and even longer than a mechanical one.
So, here are some important nuances that owners of cars with automatic transmission should understand and remember: "Kick-Down" in automatic transmission - only for extreme situations! You don't have a sports car, do you? So don't make it out of your civilian car. If you are a street racer at heart, an automatic transmission is clearly not your choice. At high speeds, the temperature of the oil in the box rises and the clutches wear out faster. And from the point of view of safety - you should not make any sudden movements while driving.
Changing the oil in the box must be done on time! That's right, if it is written in the service book - 60 thousand kilometers or two years (whichever comes first) - then this is how it should be done. The automatic transmission is extremely sensitive to the quality of the oil, and over time (mileage) - it significantly loses its performance properties. And automatic transmission repairs are very expensive.
No substitutes! If there is a special gear oil from the car manufacturer for your gearbox, use only it! Just the name ATF is usually not enough - transmission manufacturers often impose their own additional requirements on transmission oils that exceed standard quality classes, such as DEXTRON III.
At traffic lights and in traffic jams, you should absolutely not switch the transmission to the “parking” or “neutral” mode - from the fact that you stand in the “drive” mode for several minutes, the damage and wear is much (tens of times) less than from repeated switching back and forth.
In winter, the automatic transmission must be heated! Regardless of anything (brand, model, type of gear oil, etc.), start the car in frost, turn on (without releasing the brake pedal) “drive” for a few minutes, then “reverse” for a few more minutes. 4-5 minutes of such a warm-up at -10 is enough.
You should always put on the handbrake! Regardless of whether your car is on a slope or not, it is correct and safe for the automatic transmission to start and turn off the engine according to the following algorithm: Turn off the engine: stop the car completely - (without removing your foot from the brake pedal) "parking" mode - (still without releasing the brake) tighten the handbrake - turn off the engine. Start the engine: press the brake pedal - start the engine - (without releasing the brake) "drive" or "reverse" mode - remove from the handbrake release the brake.

How to "extend the life" of an automatic transmission
The automatic transmission today is gradually pushing the classic “mechanics” into the background, which is becoming the lot of very “naked” versions of budget models or the prerogative of commercial vehicles.
As the automotive industry has evolved, we have gone from simple (not really) three-speed automatic transmissions to the already fairly common eight-, nine-, and even ten-speed transmissions. Both the reliability of these units and their resource have grown, but they still cannot be compared with the performance of mechanical gearboxes. Today we will look at methods and ways by which you can extend the life of automatic transmissions and provide them with a decent old age.
First of all, the correct operation of the transmission depends on the quality of the oil used. It differs significantly from conventional motor oil in terms of service life and chemical properties. Of course, it is not necessary to change it every 8-10 thousand kilometers, but its properties gradually disappear.
Transmission oil deteriorates from too high a temperature and rotational speed of its components. It is important to remember that when changing the oil in the gearbox, use the same oil that is recommended by the manufacturer.
Replacement intervals vary greatly depending on the manufacturer. It can be either 50 thousand or 100 thousand kilometers. If the replacement interval is not prescribed in the maintenance regulations and is not indicated in the instructions, then most likely the gearbox is considered maintenance-free - oil was poured into it for the entire service life.
You can kill an automatic transmission by rough handling and frequent operation in extreme conditions and high load modes. For example, it is no coincidence that the maximum weight of a towed trailer is indicated in the instructions for a car. Excessive load can cause overheating, which leads to the oxidation of the lubricant and the gradual loss of lubricating properties. The oil darkens and acquires a characteristic burnt aroma.
Elementary attentiveness will help save the gearbox and, accordingly, the family budget with nerves. If traces of smudges are found at the parking lot of the car, it will not be superfluous to check the oil level. Unfortunately, not all cars have such an opportunity - some models are not equipped with an oil dipstick, so it will be possible to check the condition of the gearbox and the oil level only in the service.
If you find that the oil has completely darkened or its level has dropped to the maximum permissible value, then it's time to replace it. It is important to note that adding gear oil, as we do with engine oil, is not recommended. It must either be completely replaced, or use the cleaning option.
Cleaning the gearbox oil is not suitable for all models and is not at all a 100% alternative to replacing. It is highly desirable to change the oil in accordance with the regulations.
The key to the longevity of the gearbox is exceptionally timely gear shifting. You should not "stick" the parking lot until the car has completely stopped. Switching to "Drive" from high speeds is also highly undesirable. Such actions can at least seriously damage individual components, and in the worst case, simply break the unit itself. However, there are many cars on the market today with fairly traditional torque converters that are equipped with an electronic control system. What will happen to such a box when switching to the wrong position on the go, an extremely risky blogger showed.
Separately, we note that the frequent transportation of loaded trailers negatively affects the quality of the lubricant. In this case, the oil change interval is recommended to be reduced by one and a half to two times.

How to extend the life of the "machine"? | Auto-moto
Do not tow a trailer or take anyone in tow. Do not tow your own vehicle with the engine off. It is better to call a tow truck and load faulty equipment onto it.
If it’s completely unbearable, the malfunction happened “far from city noise” and there is no way to call a tow truck, then you can tow at a speed of no more than 30 kilometers per hour by setting the control lever to position N, but in no case in Drive.
At traffic lights, it’s better not to imagine yourself as a cool street racer and not to tear right off the bat. Frequent and abrupt starts for the "machine" are disastrous.
"Sowing" on the snow or in the sand, try to skid less and be sure to include a lower range. The rapid rotation of the wheels without load simulates a sharp acceleration of the car, the hydraulics are useless and shift gears at an accelerated pace, the inside of the box is experiencing extreme loads. A favorite technique of motorists is to leave “jumping”, switching the control lever alternately between positions R and D for automatic transmission is especially harmful.
Try to use the neutral mode less often - the position of the control lever N. All clutches, valves and bands are involved in it. At traffic lights and short stops, it is better to hold the car with the brake, and for long ones, turn on Parking.
When choosing a car, pay attention to its mileage and age. Automatic boxes are reliable units, but not magical, their resource is finite. With proper care, it reaches 200-300 thousand mileage or 10-15 years of operation. After that, the box slowly but surely and not always noticeable to the eye begins to “die”. Perhaps you will last another five years on it, but maybe you will not have time to get to the garage.
If a tow hitch is installed on the machine, then it was used to tow a trailer. Sometimes the trailer is removed so as not to embarrass the buyer. Having found traces of installation, it can be assumed that the owner wants to hide the fact that the car was used as a tugboat, not without reason.
Oil in a serviceable box, even without replacement, with high mileage should be dark brown and slightly transparent. Thick black oil indicates the need for repair.
This is also evidenced by small inclusions, lack of transparency, the smell of burning or a whitish emulsion shade. To see, drop the oil on a white piece of paper.
When viewed on a flyover, there should be no traces of oil on the box. The complete cleanliness of the surface should equally alert, most likely, the streaks were removed with a rag.
With the engine running and the brake pedal depressed, shift the gearbox from position N alternately to D and R. Gear shifting should occur without delay, with a slight push. The switching delay of more than a second and a half and thuds inside the box speak of its deplorable state. The start of movement and gear shifting with a “healthy” box should not be accompanied by jerks and jerks.
The more attentive and picky you are when buying a car, the less trouble it will give you in the future. Good luck on the roads.

We continue our conversation with the director of the "Automatic Transmission Group" Vladimir Drozdovsky about how to extend the period of automatic transmission uptime.
The design of modern automatic transmissions has been worked out over a long period of time and is quite reliable. Constant, modest care can extend the life of an automatic transmission for many years.
Maintenance
Automatic transmission maintenance consists in a visual inspection of the automatic transmission for presence, in periodic monitoring and adding oil to the operating level or, if necessary, replacing it and making adjustments (if they are provided for in the operating instructions). Let's consider these questions in more detail.
When approaching a car that has been standing on a dry, clean base for a long time (in a garage, in a parking lot), never be lazy to look under the bottom of your faithful horse and ask if oil stains have appeared under it. Their presence indicates oil leaks, which should be eliminated in a timely manner. This applies not only to automatic transmissions, but also to other vehicle components that have oil lubrication. Since automatic transmission oil has a specific color, you will be able to detect an automatic transmission leak without waiting for the case when you manage to raise the car on a lift.
Remember: timely detection and elimination of a malfunction minimizes negative consequences. The procedure for checking the oil level was discussed earlier, and it makes no sense to repeat, we only recall the main thing: the oil level is always monitored with the engine running and warmed up to operating temperature. Otherwise, the measurement error may reach 20-25%.
In automatic transmissions equipped with a pipe for measuring the oil level, oil is added directly through the pipe. For other automatic transmission designs, this procedure can be much more complicated. In this case, you should carefully read the instructions or seek help from specialists.
Before draining the oil from the automatic transmission, it is necessary to warm up the engine to operating temperature. Then you need to unscrew the drain plug located at the bottom of the box body.
At the same time, the filter element, located, as a rule, inside the automatic transmission, should be changed, for which the oil pan is removed. At the same time, an additional amount of old oil is drained.
In any case, it is not possible to completely drain the old oil from the box without disassembling it; 50 to 80% of the oil must be replaced.
After installing a new oil filter, put the pan in place, close the drain hole with a plug and add new oil through the filler hole.
Attention! When topping up or changing oil, remember: in no case should the oil be overfilled above the specified level. There is a real danger that the oil will be "captured" by the automatic transmission clutches. The consequence of this may be an avalanche-like foaming and the release of a large portion of oil from the box breather.
Some automatic transmissions have bolts to adjust the free play of the brake bands. Adjusting bolts can be located both outside and inside the automatic transmission.
The operating instructions provide for an adjustment at every oil change.
The procedure consists in tightening the bolts with a torque wrench with a certain force and unscrewing them by the number of revolutions indicated in the instructions.
Failure to comply with this rule over time leads to slippage of the friction bands in individual gears or to the absence of gear shifting at all.
Currently, Dexron brand oils are used in automatic transmissions. They are made by different companies and differ from each other mainly in color. Most of the oils have a red (ruby) color, but there are orange and green oils. Oils of different colors are not recommended to be mixed. Otherwise, they are completely interchangeable. Some modern automatic transmissions use special oils, so we strongly recommend that you follow the instructions in the operating instructions.
The average mileage before changing the oil in an automatic transmission is 50-70 thousand km, and if the car is operated in special units, then this period is reduced to 30-40 thousand km.
When changing the oil, be sure to change the automatic transmission filter. To do this, it is better to resort to the help of specialists: they will be able to tell you about the state of the automatic transmission by the presence and type of deposits in the sump.
Failure to comply with the timing of the oil change will not have a sharp impact on the performance of the automatic transmission. However, structural changes in the oil over time lead to deterioration of its anti-wear, extreme pressure, etc. properties. properties, which in the future will lead to more intensive wear of rubbing surfaces and a decrease in the life of the automatic transmission.
Practical experience shows that adding any additives to automatic transmission oil is at best useless, and at worst it can damage the automatic transmission. Therefore, we recommend that you do without additives, check the oil level more often and replace it in time.
At each oil change, the tension of the brake bands must be adjusted with the adjusting bolts.
Typical malfunctions
There is a large group of malfunctions, one way or another leading to a drop in the oil level in the automatic transmission.
If, by regularly measuring the oil level, you notice that it has decreased, first of all, inspect the automatic transmission for external leaks. They may appear as a result of a violation of the integrity of the gasket, stuffing box seals, etc.
If oil leaks are found, they must be repaired. The greater the loss, the sooner it is necessary to undertake repairs.
The worst thing is leakage in the area of the connector plane of the automatic transmission crankcase and the engine, the cause of which, as a rule, is a violation of the tightness of the automatic transmission front oil seal. Its replacement is associated with the removal of the gearbox, which is a very time-consuming and expensive "pleasure".
If the oil level in the automatic transmission drops, and traces of a leak cannot be found, then there may be several reasons.
One of them is a malfunction of the vacuum corrector used in automatic transmissions of Mercedes, Ford, General Motors, Nissan, etc.
The automatic transmission vacuum corrector is connected by a pipe to the engine intake manifold. Inside it is a membrane that reacts to the degree of vacuum in the collector.
When the membrane breaks, the oil from the internal cavity of the automatic transmission is sucked into the engine intake manifold. At the same time, the opacity of the exhaust increases, the smoke acquires a bluish tint. The intensity of smoke depends on the degree of destruction of the membrane.
In some cases, this defect is accompanied by an increase in the oil level in the engine.
To clarify the diagnosis, at the first suspicion of a malfunction of the vacuum corrector, it is necessary to disconnect the pipe from it and check with a clean match if there is any oil left in it. For a working vacuum corrector, the nozzle must be dry. If an oil film is found in the nozzle, the vacuum corrector will have to be replaced.
This malfunction is very insidious, since its external manifestations are not too noticeable, and the consequences can be catastrophic: an automatic transmission, forced to work for a long time with a reduced amount of oil, will fail, and literally not a single "living" part will remain in it.
Another reason for the slow drop in the oil level in the automatic transmission in the absence of traces of external leaks may be oil seepage into the engine cooling system.
During the operation of an automatic transmission, the oil temperature can rise to 150 C. To ensure its performance, it must be cooled, which in most cases is achieved by integrating an automatic transmission oil system radiator into the engine cooling system filled with antifreeze. If the oil cooler leaks, oil from it begins to enter the engine radiator. This happens because when the engine is running, the pressure in the automatic transmission radiator is higher than the pressure of the engine cooling system.
When the engine is turned off, the picture changes: antifreeze begins to penetrate into the transmission oil.
At the initial stage, an oil film can be found on the surface of the antifreeze under the radiator cap.
Further development of this process leads to the appearance of an emulsion both in the engine and in the automatic transmission. Once inside the automatic transmission, antifreeze corrodes the adhesive base of the friction elements, which causes the friction layer to peel off and corrosion of the internal elements, and also worsens the lubricating properties of the oil.
If this process has begun recently, then replacing the oil cooler and flushing the box two or three times by changing the oil can sometimes revive the automatic transmission to life.
Flushing the automatic transmission can only be done with gear oil. The use of other liquids for this purpose is unacceptable.
The conclusion is simple: often unscrew the radiator cap of the engine cooling system and check the antifreeze for traces of oil.
Another common malfunction is a break in the tube connecting the automatic transmission to the oil cooler.
In this case, in 1-2 minutes, all the oil is drained from the box, and it ceases to function. If at the same time the driver immediately stopped and turned off the engine, then after replacing the tube and adding oil to the required level, the automatic transmission will restore its performance in 90% of cases.
A number of automatic transmission malfunctions are associated with improper adjustment of the power control cable (thrust), destruction of its braid or breakage of the cable itself. As a result, there is a lack of automatic switching, their delay or premature operation. To fix this problem, you should contact the auto repair shop.
When operating automatic transmissions with electronic control from the on-board processor, it happens that some kind of warning signal is displayed on the dashboard while driving. The automatic transmission stops shifting and allows you to continue moving forward in only one gear, in the so-called security mode.
This means that the computer has detected some malfunctions in the automatic transmission control circuits or inside it that need to be eliminated. The security mode allows you to move without sharp accelerations for a short time, sufficient to get to the nearest technical station. When driving in security mode, the engine speed should not exceed 2000 rpm. Failure to comply with this rule leads to the fact that the main pressure becomes much higher than the norm provided for by the designers of the box. The front pump, forced to work in overload mode for a long time, does not stand up, and the automatic transmission literally falls apart before our eyes.
Having reached the technical station in security mode, it is necessary to carry out computer diagnostics of automatic transmission systems in order to determine the defect and, having detected it, eliminate it.
In conclusion, I would like to say that all car systems are closely interconnected. In most cases, the normal functioning of one of the systems is determined by the equally stable operation of others.
This fully applies to automatic transmission, for the effective operation of which it is necessary to extract more power from the engine than a mechanical transmission requires. Since the automatic transmission “smoothes out” the symptoms of many engine problems, in the event of a breakdown, non-professionals primarily blame the automatic transmission, while it often turns out to be nothing. Upon closer examination, it turns out that the transmission is intact, but some of the engine systems "flew".
Thus, before dealing with the gearbox, make sure that the engine, including all its systems (fuel, gas distribution, ignition, control), is operating normally and developing the specified power.
What measures should be taken to ensure that the automatic transmission lasts as long as possible? Compliance with a few simple rules will save the automatic transmission from premature failure and, accordingly, the cost of its restoration.
Most advisers from among Internet specialists offer regular changes in the transmission fluid as almost the only guarantee of the longevity of the machine. It comes to advice, change the ATF at least thirty thousand miles. Of course, this will not make your transmission worse, but it will not give a significant effect, especially if you operate the box incorrectly.
warming up
Before driving, the automatic transmission should be warmed up
The first rule that must be observed is that before the trip, the units should be warmed up, not only the engine, but also the automatic transmission, so that the ATF in the box acquires a working consistency and can circulate normally in the system. From the course of physics, we know that thick oil cannot ensure the proper quality of lubrication of the moving parts of the unit. However, standing with the engine running for a while will not be enough. The procedure is as follows: depress the brake pedal, switch the selector to Drive mode, stand like this for a couple of minutes, return the selector to its place, depress the pedal. Everything, the box is warmed up, you can go where you want.
Don't jerk off
When traveling in the city, there are always a lot of traffic lights at which you have to make short stops. So, it’s not worth moving the selector to position N at each such stop, these extra movements do not benefit the unit, and any other mechanism. If you want to save the AKN of your iron horse, never arrange unnecessary traffic light races. By sinking the trigger to the floor, you cause friction slippage, which is simply inevitable in such a mode. This significantly shortens the life of the machine.
Change bands less frequently
Overheat
It is also not very useful for an automatic transmission and overheating, however, it is quite difficult to call it on modern cars in normal mode. However, some manage to do this by skidding for a long time on ice slides or sand. In addition, overheating can be caused by attaching an overly heavy trailer to the towbar, or cordially fulfilling the neighbor’s request, towing his car (rather big) to a car service, pulling a stuck “off-road vehicle” out of the mud. Of course, such bullying will not kill your machine at all, but failed clutches will result in a very expensive repair for you. In most cases, they have to be completely replaced.
Do not overheat automatic transmission
Also, in no case should you ride in tow if the engine does not start. The fact is that without a running engine, the oil pump does not work, and the gears of the box will be completely without lubrication, because only the pump circulates the oil. In some guides, automakers allow towing, but at a speed no higher than 25 kilometers per hour and no further than 20 kilometers. But still it is better to accustom yourself not to use this method, a tow truck is always available for a call. So you will know for sure that you have done everything to extend the life of your automatic transmission.
So far nothing has been invented that is eternal, but enough has been invented that is durable. In particular, it is an automatic transmission. She can walk many tens of thousands of kilometers without problems if you yourself do not contribute to her sudden death. How to extend the life of an automatic transmission, we will briefly tell you in this article.
In order for the “automatic box” to last as long as possible, you need to carefully look after it. First of all, you should change the oil with filters on time or even more often than usual. It is not so easy to drain the old oil from the machine in the courtyard of the house, so changing the oil in the automatic transmission at the service station seems to be the most expedient act in this case. In Russia, operating conditions can almost always be classified as difficult. Therefore, it is better to change the fluid with filters twice as often.
Why do we make such recommendations? Everything is simple. When the automatic transmission is working, a lot of metal chips are formed in its depths. They clog the filter and are partially carried throughout the mechanism. The chips, being an abrasive, begin to grind down the metal, as a result of which even more chips are formed, grinding is even more active, etc. If the box always contains the required amount of clean oil, coupled with fresh filters, then the long and flawless operation of the mechanism is guaranteed.
In cold weather, always warm up the automatic transmission before starting. To do this, press the brake pedal and then switch the selector to position D (Drive). At least a minute you need to stand like that (with the brake pedal depressed) so that the lubricant has time to warm up and lubricate all the gears of the “automatic”.
But that's not all. Here are some additional tips for proper operation of the automatic transmission:
- Try not to skid. If this is unavoidable, try not to get carried away. If there is a low gear mode, be sure to use it.
- If the car has to stand on an inclined surface for a long time, it is better to turn on the handbrake - you should not load the transmission mechanism in vain. In a normal parking area, the P (Parking) mode will suffice.
- Neutral (N) is required only when towing. But ideally, it is impossible to tow a car with automatic transmission, although it is allowed to ride a rope no faster than 40 km / h and no further than 40 km.
- The automatic transmission selector must not be switched while driving. It is necessary to turn on the modes smoothly, avoiding sudden movements. In addition, we note that abrupt starts also harm the automatic transmission.
- If you need to drive in reverse, then before switching to position R, it is recommended to hold the selector for 3-4 seconds in neutral.
If you want to extend the life of the automatic transmission of your favorite car, then treat the transmission correctly and carefully. Only in this way will she live with you for the longest possible time. Remember that even contract "machines" are in price today. Well, if your “box”, nevertheless, has stopped working as it should, then we recommend that you contact the service center “Automatic transmission LIGA” -
