What do the letters on an automatic transmission stand for?

[OLucy]

Here are the meanings of the automatic transmission gear positions R, N, D, and L: 1. R stands for Reverse, which can only be engaged when the vehicle is stationary. For models with a lock button, the button must be pressed to switch to this gear. 2. N stands for Neutral, used for temporary stops to halt the vehicle's movement without interrupting power. For example, at traffic lights, the handbrake should also be engaged, and this gear should not be used when going downhill. 3. D stands for Drive, the most commonly used gear. Gear shifts can be controlled via the accelerator when needed. D1 (or L gear), D2, and D3 correspond to manual transmission gears 1 and 2, 3 and 4, and 5 and 6, respectively. 4. L stands for Low, used when going downhill to reduce brake usage, or when going uphill for more powerful climbing.
