What are the automatic transmission gears in cars?

Automatic transmission gears include the parking gear, reverse gear, neutral gear, drive gear, and low gear. The detailed introduction of automatic transmission gears is as follows:1. P (Parking) gear: When the car is parked and not in use, the gear is in this position, and the wheels are mechanically locked to prevent rolling. The vehicle must be completely stopped before using the P gear, otherwise the mechanical part of the automatic transmission may be damaged. In addition, automatic transmission vehicles are equipped with a neutral start switch, which ensures that the engine can only be started in the "P" or "N" gear to prevent the car from suddenly moving forward if started by mistake in other gears.2. R (Reverse) gear: When reversing, automatic transmission cars cannot use the clutch like manual transmission cars, so special attention must be paid to the control of the accelerator pedal. Usually, the safety button on the shift lever must be pressed to move the lever to the "R" gear. The gear must not be forced into the "R" position when the vehicle is not completely stopped, otherwise the transmission may be severely damaged.3. N (Neutral) gear: This gear is used for temporary parking (e.g., at a red light). Note that this gear indicates neutral, and to prevent the car from rolling on a slope, the brake must be pressed.4. D (Drive) gear, also known as the driving gear: In the D gear, the transmission automatically shifts between overdrive gears (equivalent to gears 1 to 4) based on speed and throttle conditions. This gear is used for normal road driving.5. L (Low) gear: When going downhill or on a long slope, shifting to this gear limits the car to the lowest gear, allowing the engine to assist in braking. This prevents the driver from having to press the brake for a long time, which could overheat the brake pads and cause danger.
I find driving an automatic transmission car very convenient in daily life. The main gears are just the basic ones: P, R, N, and D. The P gear is for parking, like when you've stopped the car and engage it to lock the transmission; the R gear for reverse requires pressing a button or turning a knob; the N neutral gear is suitable for waiting at red lights or brief stops; the D drive gear is the most commonly used when driving, as the car shifts gears automatically. Some cars also have an S sport mode, making the throttle more responsive and powerful for uphill driving; the L low gear helps control speed safely when going downhill. Always remember to press the brake when shifting gears, otherwise, it can wear out the transmission and damage the car. The design of automatic transmissions is meant to reduce hassle, making daily commutes and traffic jams much less frantic and far more relaxing than manual transmissions.
