With the change in car consumption habits, automatic transmission cars are becoming more and more the first choice for car purchases. So what gears do the letters on automatic transmission cars represent?

  Automatic transmission cars do not require the driver to manually change gears. The vehicle will automatically select the appropriate gear according to the driving speed and traffic conditions.

  Automatic transmission cars use an automatic transmission, which utilizes a planetary gear mechanism to change speed and can automatically change speed according to the travel of the accelerator pedal.

Usually there are six gear positions on an automatic transmission car, from top to bottom: P, R, N, D, S, L.

 1.The P gear (abbreviation for parking) is the parking gear or parking gear. It can only be engaged when the vehicle is completely stopped. The P gear uses a mechanical device to lock the rotating parts of the car so that the car cannot move.

Note: The P gear can only be used when the vehicle is completely stopped, otherwise the mechanical part of the automatic transmission will be damaged.

2.R (abbreviation for reverse) gear, that is, reverse gear, can only be engaged when the vehicle is stationary and the engine is idling.

Note: Never use the R gear when the car is moving forward, and pay special attention to the control of the accelerator pedal when reversing.

3.N (abbreviation for neutral) gear, which means neutral gear. Use this gear and pull the handbrake when temporarily stopping (such as at a red light).

Note: To prevent the vehicle from sliding on the slope, be sure to step on the brake or pull the handbrake.

4.D (abbreviation for drive) gear, that is, the forward gear. In this gear, the car transmission can automatically shift between 1st to 5th gear. D gear is the most commonly used driving position.

D3 is also a forward gear. In this gear, the gearbox automatically switches between 1-3 gears and will not shift to 4th and 5th gears. It can be used as a limited gear when traffic is not smooth to avoid the skipping between 3rd and 4th gears.

D2 gear means 2nd gear. In this gear, the gearbox is in 2nd gear. It is used for starting on slippery roads or as a limited gear when moving slowly to avoid shifting between 1st and 2nd gears and 2nd and 3rd gears.

D1 gear means 1st gear. In this gear, the gearbox is in 1st gear.

 

5.L (abbreviation for low) gear, that is, low speed gear. After shifting into L gear, the vehicle can obtain greater output power, but will not automatically shift into high gear. It can also give full play to the braking effect of the engine to control the vehicle speed.

The L gear is often overlooked by many people. On icy roads or in traffic jams, the vehicle is moving slowly, so if the gear is in D gear, the gear will fluctuate, increasing fuel consumption. At this time, switching to L gear can ensure that the vehicle gear is always between 1st gear and 2nd gear, avoiding increased fuel consumption and vehicle wear, and is also more suitable for uphill and downhill driving.

 

6.S (abbreviation for sport) gear is the sports mode. In this mode, the gearbox can shift gears freely, but the gear shifting timing is delayed, so that the engine can maintain a high speed for a longer time, instantly output a large torque, and increase the power of the vehicle. Using other gears will be slightly worse.

Although it can accelerate instantly, this gear is mostly used when overtaking. This gear actually delays the shifting without changing other working links.
