Gearbox oil is the key to ensuring the normal operation of the gearbox. If the oil in the gearbox is insufficient or the oil quality deteriorates, it may cause insufficient lubrication of the internal parts of the gearbox and produce abnormal noises. In addition, if the transmission oil is not replaced for a long time, its cleanliness and lubrication performance will be reduced, and abnormal noises may also be caused.

2. gear wear

As the vehicle's mileage increases, the gears inside the transmission may produce gaps due to wear, which may produce abnormal sounds when the gears are engaged. Especially in vehicles with high mileage, gear wear is a common cause of abnormal sound in the gearbox.

3. bearing damage

If the bearings in the gearbox are damaged, abnormal noises will also occur. Bearing damage may be natural wear due to long-term use, or it may be premature wear due to insufficient transmission oil or oil quality problems. Bearing damage will not only generate noise, but may also affect the normal operation of the gearbox.

4. Synchronizer problem

Synchronizer is an important component in the gearbox for smooth shifting. If the synchronizer is worn or damaged, metal friction sounds may occur when shifting gears, which is a common cause of abnormal sound in the gearbox. Synchronizer problems often require professional testing and repair.

5. Loose internal parts

If there are loose parts inside the gearbox, such as bolts, washers, etc., abnormal noises may also occur when the vehicle is running. In this case, the transmission needs to be thoroughly inspected to identify loose parts and tighten or replace them.

In order to better understand the reasons for the abnormal sound of the gearbox, the following is a simple table summarizing the above possible reasons and their characteristics:

In short, abnormal noises in Passat transmissions can be caused by many factors, including transmission oil problems, gear wear, bearing damage, synchronizer problems and loose internal parts. Car owners should regularly check the status of transmission oil, pay attention to abnormal sounds of the vehicle, and conduct professional inspections and repairs in a timely manner when problems are discovered to ensure driving safety and vehicle performance.
