Which Practices Can Affect the Lifespan of a CVT Transmission?
1 Answers
Coasting in neutral and suddenly shifting from D to N gear can affect the lifespan of a CVT transmission. Below is a detailed explanation: 1. Coasting in neutral may damage the transmission: Coasting in neutral can potentially harm the transmission. Automatic transmissions rely on hydraulic control, which requires stable hydraulic system pressure. The oil pump's power comes from the engine, and in neutral, the oil pump lacks sufficient power, leading to insufficient oil pressure. When in D gear, oil pressure can reach up to several tens of kilograms per square centimeter, whereas in N gear, it drops to around 25 kilograms per square centimeter. 2. Suddenly shifting from D to N gear can cause damage: If the car is shifted suddenly from D to N gear while driving, the oil pressure drops abruptly, resulting in poor lubrication for the moving and clamping components. This leads to severe sliding friction, which can cause pressure leaks or high temperatures inside the CVT transmission, potentially resulting in significant damage.
