Motorists should remember that a car with a box of automatic transmission requires close attention and knowledge of control rules, especially in critical situations. If it's winter and you risk falling into a trap from the snow, listen to the advice of experts on how to deal with snow jams. It is unequivocal to say - it is impossible to slip on an automatic box - not quite right, there is always a way out.
Box cooling
Under automatic transmission, heat is emitted both by friction discs and a torque converter; under heavy loads, overheating is extremely high; for this purpose, powerful automatic cooling means are provided for machines with automatic machines. The radiator is built into the element in the engine cooling radiator, or it is cooled with a separate air flow.
With a long slip, the temperature of the lubricant of the automatic box rises abruptly, including boiling. This leads to the destruction of the friction discs, forced to work "for hard".In the worst case, it can lead to transmission failure.
Conclusion 1. To slip on the automatic transmission is permissible, but not for long and with interruptions.
Slipping on a warm car
If you start slipping on a “cold” car, the lubricant will not warm up enough, which will also lead to a hard work of the box elements and their rapid wear. Turn on the pre-R mode and warm up the car to the minute. Lubrication will be brought into working condition, after which you can begin to slip.
Conclusion 2. Heat the car before slipping.
Gear fixation
During slip, the torque converter receives the greatest load, which is fraught with removing it from the operating state. At high temperatures, the properties of the liquid oil change, and the pressure may drop, which can reduce the friction discs to burnout. Try to clearly record the transfer, without changing its position in the process of slipping. Change from “R” mode to “D” via the brake pedal.
Conclusion 3. It is strictly forbidden to squeeze the brake and gas together.
Road grip
The frictions wear out under any serious load, be it towing, skidding, or overestimated driving speed.A special element is provided in the automatic transmission - a differential gearbox with a long axis that runs along its body. When a wheel hits a hard surface, a very strong blow to the axle is possible, which is capable of tearing it out with further penetration of the box body.
Conclusion 4. Do not allow a sharp grip with 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. Cars with high mileage suffer from a strong deterioration of the torque converter. The radiator cooling box clogged with time, which requires the immediate replacement of the automatic transmission. If you are the owner of such a car, and are not ready to abandon your beloved friend, try not to go in strong snow drifts in long-distance routes.
If your car is “Japanese” or “European” of an old model, an automatic cooling system of the automatic box can be built in it, while on the surface of the torque converter are installed auxiliary external vanes, which are engaged in air circulation to remove the temperature.Here such automatic transmissions can be cooled only in the course of movement, therefore it is contraindicated to slip on them.
Conclusion 5. Current models of cars of Japanese and European manufacturers with automatic transmissions do not suffer from this drawback; you will get out of the snow drifts without any problems.
For a real motorist or an experienced professional, there are no insoluble problems on the roads. The main thing is to know your car as your own, and to listen to the advice of sages on driving.
