How can you screw up an automatic transmission in a car, the expert said “Behind the wheel” Mikhail Kolodochkin. There are many ways, but one of them deserves special attention.
The warm season has already passed, and before the trip you need to think about the fact that the machine components need to be warmed up. But if the majority is more or less tolerant of warming up the engine, then not everyone suspects that the box needs to be warmed up.
In addition, the automatic transmission takes longer to warm up, because it only warms up due to friction in the gears and clutches. Once the engine has started and the transmission fluid becomes less viscous (but still doesn’t warm up much), you can start moving smoothly.
The normal temperature of the working fluid in the machine is between 50 and 90°C. And if you immediately give the machine a big load, you can lose both seals and seals.
The duration of the gentle ride depends on the ambient temperature.
You can warm up the box and stand still. To do this, set the selector switch to position D or R while holding the brake down. And let the machine run in these modes for a minute or two. The combustion engine is loaded by a torque converter, one part of which rotates and the other is stopped together with the wheels. The engine warms up faster and the intensive mixing of the fluid in the torque converter leads to an accelerated warm-up of the gearbox.
Insufficient warming up is just one of the reasons that can disable an automatic transmission. All the details – in the material “How drivers screw up the automatic transmission – 6 blunders.”
