What gear is generally used when driving an automatic transmission car?

[VonBriella]

Automatic transmission cars generally use D (Drive) gear or S (Sport) gear when driving. Here is more information about the various gears in an automatic transmission car: P (Park) gear: The P gear is the parking gear, used when the vehicle is parked for an extended period. It locks the vehicle's rotating parts mechanically within the transmission to prevent movement. For automatic transmission models, it is necessary to engage the parking brake first and then shift into P gear; otherwise, the mechanical parts of the automatic transmission may be damaged. R (Reverse) gear: The R gear is the reverse gear, used when the vehicle needs to move backward. When the gearshift lever is in R gear, the hydraulic system connects the reverse oil circuit, causing the drive wheels to rotate in reverse for backward movement. To operate, you must press the brake pedal and press the shift lock on the gearshift lever before moving it to R gear. It is important to note that you should not force the gearshift lever into R gear when the vehicle has not completely stopped, as this can damage the transmission. N (Neutral) gear: The N gear is the neutral gear, used when the vehicle is parked for a short time without turning off the engine, such as when waiting at a red light or in traffic. When shifted into N gear, the engine's power is not transmitted to the wheels, and pressing the accelerator will not move the vehicle. D (Drive) gear: The D gear is also known as the forward gear or drive gear. When the gearshift lever is in D gear, the vehicle automatically shifts gears based on throttle opening and speed data. This gear is suitable for normal road driving, and the driver can control the speed by adjusting the accelerator pedal. S (Sport) gear: The S gear represents Sport mode, allowing the vehicle to accelerate quickly, which is suitable for overtaking or climbing steep hills.
