What are the gear positions in an automatic transmission car?
1 Answers
Introduction to automatic transmission gear positions is as follows: 1. P (Parking) - Parking gear: P is used for parking, which utilizes a mechanical device to lock the car's rotating parts, preventing the car from moving. When the engine is running, as long as the gear lever is in the driving position, an automatic transmission car can move easily. 2. R (Reverse) - Reverse gear: R is used when reversing. Unlike manual transmission cars, automatic transmission cars cannot use semi-clutch, so special attention should be paid to the control of the accelerator pedal when reversing. Usually, the safety button on the lever must be pressed to move the lever to the "R" position. 3. N (Neutral) - Neutral gear: N refers to the neutral position, which can be used when starting, towing, or during temporary stops (such as at a red light). To prevent the car from rolling on a slope, the brake must be pressed when in neutral. When the lever is placed in the "N" position, the power between the engine and the transmission is cut off. For short stops, the lever can be placed in this position, and the handbrake can be pulled, allowing the right foot to move away from the brake pedal for a short rest. 4. D (Drive) - Drive gear, also known as the driving gear: In this position, the transmission automatically shifts between 1st gear and overdrive (equivalent to 1st to 4th gear) based on speed and throttle conditions. This gear is used for normal road driving. Due to different designs in various countries, the "D" gear generally includes shifting from 1st gear to high gear or from 2nd gear to high gear, and it will automatically shift based on changes in speed and load. 5. D3/D2/D1 - Forward gears: Although D3/D2/D1 are also forward gears, they have slight differences from the D gear. These gears do not shift based on normal engine speed; instead, they allow the car to have higher engine speeds at the same speed, providing greater power and torque output. They are generally used for high-speed overtaking and climbing steep slopes. Some cars do not have D3, with D2 directly below the D gear.
