What is the full name of the R gear?

[OBradley]

R gear stands for Reverse. Below is a detailed introduction to car gear positions: 1. R gear (Reverse gear): When this gear is engaged, it connects the hydraulic system's reverse gear oil circuit, causing the drive wheels to rotate in reverse for backward movement. Do not forcibly shift to the "R" gear when the vehicle is not completely stopped, as this may damage the transmission. 2. N gear (Neutral gear): When neutral is engaged, the planetary gear system idles and cannot output power. 3. D gear (Drive gear): When the gear shift lever is in this position, the hydraulic control system automatically connects the corresponding forward gear oil circuit based on throttle opening and vehicle speed signals. It can automatically shift up or down according to driving speed, achieving automatic transmission functionality. 4. P gear (Park gear): This uses a mechanical device to lock the rotating parts of the car's tires, preventing the vehicle from moving. 5. L gear (Low gear or Limited gear): The transmission can only switch between limited gears. "1" or "L" is the lowest gear of the transmission, typically used only when extremely strong power is needed, such as climbing steep slopes or towing heavy vehicles.
