What are the reasons for severe jerking in Wanliyang CVT25?

[JesseLynn]

The reasons and solutions for severe jerking in Wanliyang CVT25 are as follows: 1. Insufficient lubrication: Since most mainstream CVT transmissions require oil, insufficient lubrication during cold starts may lead to poor connection between the chains. This can easily cause impact when the clutch engages during cold starts, resulting in jerking when shifting gears. Solution: To avoid this, ensure the vehicle is warmed up and press the brake firmly when shifting to allow the clutch to engage smoothly. 2. Design and quality issues: CVT failures are mainly caused by poor torque converter design (connecting the transmission body and the engine), which can lead to shifting impacts at any speed. Additionally, poor quality and excessive chain wear beyond normal values can cause a large amount of metal shavings to accumulate in the oil pan, leading to vibrations in the CVT transmission, though not severe jerking. Solution: Seek professional repair at a specialized maintenance shop.
