Yes, it is necessary to warm up the automatic transmission in winter. Here are some reasons:
* Reduced wear: Transmission fluid in an automatic transmission thickens at low temperatures, which makes it difficult to circulate and lubricate the components of the transmission. Warming up the liquid makes it less viscous and allows it to circulate better.
* Improved Shifting: Thick fluid can make gear shifting difficult, leading to jerking and premature wear. Warming up the fluid makes gear shifting easier.
* Extending the life of the box: Regularly warming up the box can help extend its life by reducing wear and preventing breakdowns.
How to warm up an automatic transmission in winter:
* Start the car and let it idle for about 5-10 minutes.
* Shift the gear selector to “D” or “R” to circulate the fluid.
* Apply and release the brake several times to build up pressure in the system.
* Ride for a short distance at low speed (20-30 km/h).
*After you have driven a few kilometers, the fluid should warm up.
