In automatic transmission vehicles, the P stands for Park, R stands for Reverse, D stands for Drive, N stands for Neutral, and L stands for Low gear. Below are some important notes on gear usage: 1. Check the gear position before starting: Since automatic transmissions are equipped with a neutral start switch, the engine can only be started when the gear shift lever is in P or N position. This prevents the car from lurching forward if started accidentally in other gears. Therefore, always ensure the gear shift lever is in P or N before starting the engine. 2. Avoid coasting in neutral at high speeds: Some drivers shift to N (Neutral) when driving at high speeds or going downhill to save fuel, but this can potentially damage the transmission. When the transmission output shaft rotates at high speed while the engine idles, the transmission oil pump may not supply sufficient oil, leading to poor lubrication. This can cause the driven plates to rotate at high speeds under the wheels' influence, potentially resulting in resonance, slippage, and other adverse effects.
