Car enthusiasts should remember that a car with a automatic gearbox requires close attention and knowledge of control rules, especially in critical situations. If the street is winter, and you risk falling into a trap from the snow, listen to the advice of specialists on how to behave in cases of snow jams. Definitely say - you can’t skid on an automatic box - not quite right, there is always a way out.
Box cooling
Heat in automatic transmission is generated by both friction discs and a torque converter, with heavy loads the overheating is extremely high, for this in machines with automatic transmission a powerful cooling means is provided. The radiator is integrated into the engine cooling radiator by an element, or it is cooled using a separate air stream.
With a long skid, the temperature of the lubricant of the automatic gearbox rises sharply, up to its boiling. This leads to the destruction of friction discs, forced to work "hard". And in the worst case, it can lead to transmission failure.
Conclusion 1. Skidding on automatic transmission is permissible, but not for long and intermittently.
Skidding on a warm car
If you start slipping on a “cold” machine, the grease will not warm up enough, which will also lead to tough work of the box elements and their rapid wear. First turn on the “R” mode and warm up the car for up to a minute. The lubrication will be brought into working condition, after which you can begin to slip.
Conclusion 2. We warm the car before slipping.
Gear lock
During slipping, the torque converter receives the greatest load, which is fraught with its removal from the working state. At high temperatures, the properties of liquid oil change, pressure can drop, which can lead to friction disc burnout. Try to clearly fix the transmission without changing its position during the slipping process. Switch from “R” to “D” mode through the brake pedal.
Conclusion 3. It is strictly forbidden to squeeze the brake and gas together.
Grip
Friction clutches wear out at any serious loadings, whether it be towing, skidding or the increased speed of driving. The automatic transmission has a special element - a differential gearbox with a long axis running along its body. If the wheel hits a hard surface, a very strong blow along the axis is possible, which can tear it out with a further break through the box body.
Conclusion 4. Do not allow a sharp grip on the road immediately after slipping.
When you can not slip
Do not try to slip on the machine if your car belongs to the old monsters of the last century. High mileage vehicles suffer from severe wear on the torque converter. The box cooling radiator becomes clogged over time, which requires an immediate automatic transmission replacement. If you are the owner of such a car, and are not ready to give up your beloved friend, try not to go into heavy snowdrifts on long routes.
If your car is “Japanese” or “European” of an old model, an automatic box air cooling system can be built into it, while auxiliary external vanes are installed on the surface of the torque converter, which are engaged in air circulation to remove the temperature. These automatic transmissions can only be cooled during movement, therefore slipping on them is contraindicated.
Conclusion 5. Modern car models of the Japanese and European manufacturers with automatic transmission do not suffer from this drawback; you can get out of snowdrifts without problems on them.
For a real car enthusiast or an experienced professional, there are no insoluble problems on the road. The main thing is to know your car, as a native, and to listen to the advice of the sages from driving.
