Why does the Passat B5 suddenly lose reverse gear?
1 Answers
Passat B5 suddenly losing reverse gear can be caused by the following reasons: Transmission valve body wear: Wear of the transmission valve body leads to reduced control pressure. During startup, the engine's low RPM prevents the transmission oil pressure from quickly reaching the standard value, making it unable to keep the plunger in the correct position, resulting in incorrect startup gear engagement. Transmission contamination: Automatic transmission jerking is often not due to internal valve body damage but rather persistent dirt and impurities inside the transmission. Especially when dirt and impurities accumulate inside the valve body, forming blockages, it becomes impossible to effectively regulate oil pressure, suddenly causing the loss of reverse gear.
