Will Frequent Shifting to Neutral (N) Gear Harm the Transmission?
1 Answers
Frequent shifting to Neutral (N) gear can be divided into two scenarios: 1. Shifting during parking will not harm the transmission; 2. When the car is in normal motion, frequent shifting to N gear can indeed harm the transmission. Repeated operations may cause insufficient heat dissipation, leading to clutch damage. When the car is running normally and shifted into N gear, the vehicle continues to move at high speed, causing certain transmission components to rotate rapidly. Meanwhile, the engine idles, resulting in the automatic transmission's oil pump also operating at the engine's idle speed. The hydraulic pressure and lubrication pressure (or flow rate) generated under these conditions are insufficient to lubricate or cool the high-speed components of the automatic transmission, ultimately causing clutch damage due to inadequate heat dissipation. An automatic transmission is a gear-shifting device that can automatically change gears based on the vehicle's speed and engine RPM, as opposed to a manual transmission.
