What causes the jerking in Passat's 2nd gear?

[MayaAnn]

The reasons for jerking in Passat's 2nd gear are as follows: Solenoid valve damage: Solenoid valve damage is a major cause of jerking. When it occurs occasionally, there's no discernible pattern; when it occurs consistently, it happens at a specific speed or when shifting to a particular gear, resulting in consistent jerking. You can use a diagnostic tool to check if there are any fault codes in the transmission and to see if the data is normal. Transmission blockage: If there is sludge blocking the oil passages in the transmission's internal circulation, it can cause stumbling issues, leading to a series of transmission problems such as overheating, impact, and slippage, resulting in jerking during gear shifts.
