What does the R in automatic transmission mean?

Automatic transmission R stands for Reverse gear, which is a gear position on automatic transmission vehicles used when backing up. Automatic transmission refers to not needing to shift gears while driving, with its advantage over manual transmission being easier to operate. Additionally, automatic transmissions include continuously variable transmission (CVT), paddle-shift transmission, and electronic gear lever transmission. Automatic transmission vehicles also have P, N, D, S, and L gear positions: P stands for Parking gear; N stands for Neutral gear; D stands for Drive gear; S stands for Sport gear; L stands for Low gear. There are three types of transmissions in the market: manual transmission, automatic transmission, and semi-automatic transmission.
Hey, when I first learned to drive, I was also very curious about the R symbol on the automatic transmission. It actually stands for Reverse gear, which you use when you need the car to move backward. For example, when you want to back out of a garage or adjust your parking space after stopping, you'll need to use it. The operation is quite simple: after the car comes to a complete stop, press the brake, shift from P (Park) to R (Reverse), release the brake, and gently press the accelerator to start reversing. However, a common mistake beginners make is reversing without checking the rear situation, which is very dangerous. So, it's important to develop good driving habits—always check the mirrors and turn your head to look around before reversing to ensure there are no people or obstacles. When I first started, I often got nervous and shifted gears too quickly, causing the car to jerk. Now I know to handle it calmly. Remember, the R gear is only for reversing; don't shift into the wrong gear when moving forward to avoid damaging the transmission.
