Do automatic transmission cars need to warm up in winter?

[DeZachary]

Generally speaking, automatic transmission cars also need to warm up in winter. The purpose of warming up is to allow the engine to reach its normal operating temperature. Idling warm-up time: When starting the car in winter, you will usually find that the water temperature is relatively low, and the tachometer needle will be relatively high. At this time, it is necessary to warm up the car while idling, which means waiting in the car for about half a minute to a minute. Generally, when the engine speed drops to around 1200 RPM and the water temperature reaches about 50 degrees, you can drive away normally. Consequences of not warming up: In winter, when temperatures are low, most of the engine oil settles at the bottom of the engine. If you suddenly start driving, the oil pump cannot immediately lubricate all parts of the engine, which can cause damage to engine components.
