Why Does the Volkswagen Transmission Make a Clicking Sound at Low Speeds?

[VanJoy]

Here are the specific reasons for abnormal noises in Volkswagen transmissions: Bearing Wear and Damage: When bearings wear out, the gap increases and the fit precision decreases; when bearings are damaged, they cannot operate normally, leading to abnormal sounds and even causing damage to transmission components, exacerbating the issue. Long-term Lack of Transmission Fluid Replacement: Transmission fluid becomes thicker and less fluid, resulting in a lack of a protective layer between components. This leads to direct friction, accelerating mechanical wear and causing abnormal noises. Use of Low-Quality Transmission Fluid: Low-quality transmission fluid has poor heat resistance and is prone to oxidation, forming sludge and debris that can clog filters and oil passages. This increases friction between internal transmission components, leading to abnormal noises in the vehicle.
