What is the detailed introduction of car gears?

Generally, there are six gear positions on an automatic transmission car, from top to bottom: P, R, N, D, S, L. Below is the detailed introduction about car gears: 1. P (Parking Gear): When parking, the car gear needs to be placed in this position. The gear uses the internal design of the car to control the rotation of the car's P system, ensuring that the car does not move even on inclined ground. 2. R (Reverse Gear): Usually, you need to press the safety button device on the gearshift to move the gear lever to the R position. 3. N (Neutral Gear): This can be used when starting the car or during towing. 4. D (Drive Gear): During normal driving, place the gear selector in the D position, and the car will automatically shift between gears 1 to 4 (or 3). 5. S, L (Low Gears): The automatic transmission operates in a low gear range in the S or L positions, which can be used in situations such as driving on slopes.
I feel as familiar with car gears as with old friends. After driving manual transmission cars for so many years, I know exactly how to use each position. R is the reverse gear, only engaged when you want to back up after parking; neutral N is for waiting at red lights, giving the engine a little rest; gears 1 through 6 are for forward driving—start with 1st gear, gradually shift up, and use 5th or 6th gear for high speeds. In city traffic jams, I often stay in 2nd or 3rd gear to avoid stalling. When going downhill, shift to a lower gear like 3rd to naturally slow down and save the brake pads. Remember, shift quickly but gently—never force it, or you'll damage the clutch. Automatic transmission cars are similar: P is for parking and locking the wheels, R for reverse, N for neutral, and D for driving. I recommend beginners read the manual more and practice shifting rhythms.
As someone who works on cars every day, I've seen too many gear-related issues. A car's gear system is mainly divided into manual and automatic types. Manual transmissions have distinct gear ratio changes, requiring the clutch to be depressed for shifting; automatic transmissions are smarter, with the computer controlling gear shifts when in Drive (D). Common positions: Park (P) locks the drivetrain and must be engaged when parking; Reverse (R) is for backing up and should only be engaged after the car comes to a complete stop; Neutral (N) allows the engine to run while the wheels spin freely; Drive (D) controls forward acceleration. Some cars also have Sport (S) mode or Low (L) gear for climbing hills. Incorrect gear engagement, such as shifting into reverse while moving forward, may damage the transmission or cause accidents. Regular inspection of the gear lever and sensors is crucial to ensure smooth operation.
