What are the reasons for severe jerking in Wanliyang CVT25?

[Jade]

The reasons and solutions for severe jerking in Wanliyang CVT25 are as follows: 1. Insufficient lubrication: Since most mainstream CVT transmissions require fluid, insufficient lubrication during cold starts may lead to poor connection between the chains. This can cause impact when the clutch engages during cold starts, resulting in gear-shifting jerking. Solution: To avoid this, ensure the car is warmed up and firmly press the brake when shifting gears 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 to the engine), leading to shifting impacts that can occur at any speed. Additionally, poor quality and excessive chain wear beyond normal values can cause the oil pan to accumulate a large amount of metal shavings, potentially leading to vibrations in the CVT transmission, though not severe jerking. Solution: Seek professional repair at a specialized maintenance shop.
