The duration of warming up an automatic transmission in winter depends on several factors:
* Ambient temperature: the colder it is, the longer it takes to warm up.
* Transmission fluid type: synthetic fluids warm up faster than mineral ones.
* Transmission condition: A transmission with worn parts may require a longer warm-up period.
General rule for warming up automatic transmission in winter:
* 10-15 minutes: At temperatures between 0°C and -10°C.
* 15-20 minutes: At temperatures between -10°C and -20°C.
* 20-25 minutes: At temperatures below -20°C.
Step-by-step process for warming up the automatic transmission in winter:
1. Start the engine and let it idle for 5-10 minutes.
2. Move the automatic transmission selector to position “D” (Drive) and keep your foot on the brake.
3. Slowly increase engine speed to 1500-2000 rpm and hold it for 1-2 minutes.
4. Repeat steps 2 and 3 with the “R” (Reverse), “N” (Neutral) and “P” (Park) positions.
5. Start at low speed and gradually increase speed. Avoid sudden acceleration or towing of the drive.
Adviсe:
* Use transmission fluid recommended by the manufacturer for cold climates.
* If the car has been parked in the cold for a long time, let it sit in a warm garage or warm it up using an external heat source before starting it.
* Check the level and condition of the transmission fluid regularly.
* Avoid prolonged wheel slippage, as this can lead to overheating of the automatic transmission.
