What is the gear for automatic transmission on highways?

[IslaAnn]

On highways, the gear for automatic transmission is the D gear. The D gear is the forward driving gear, which shifts up according to the set program, making it relatively more fuel-efficient. The D gear is practical in various situations and is also very beneficial for the car's transmission. Drivers on highways can choose to use the D gear, which is also quite convenient. The gear used when the car is moving forward, most automatic transmission cars have the D gear designed with a sequence from 1st gear to high gear, while some have a sequence from 2nd gear to high gear. When driving, simply place the gear shift lever in the D gear, and the car's speed will be controlled by the accelerator. Drivers should always be mindful that the S gear should not be used for extended periods, as prolonged use of the S gear can subject the car's engine to excessive pressure, potentially damaging the engine. If you want to accelerate quickly, you can use the S gear.
