What Causes the Transmission Noise When Releasing the Throttle in a Jetta?

[LeCollin]

Jetta releasing the throttle transmission noise reasons are as follows: Bearing wear and damage: When the bearing is damaged, it cannot operate normally, resulting in abnormal noise and even damaging the transmission components, leading to further malfunctions. This can be caused by the wear of transmission components or the use of replacement parts with insufficient precision, such as excessive clearance between worn or new gears and the original gears. Poor lubrication: In this case, the corresponding lubricant should be replaced; otherwise, it will accelerate transmission wear and shorten its service life. Loose transmission bolts: Vibration during use can loosen the bolts, so regular inspections are necessary.
