How often should the automatic transmission fluid be changed in a Passat?

[JosephineAnn]

Passat automatic transmission fluid needs to be changed every 60,000 kilometers. Hazards of insufficient transmission fluid: Insufficient transmission fluid can lead to difficulties in shifting gears and increased noise during transmission operation. This is because the meshing and transmission of gears during operation generate significant heat and metal debris from wear. Without the cleaning and cooling effects of lubricating oil, friction between gears increases, resulting in noise and shifting difficulties. Prolonged lack of fluid can cause severe gear wear and even render the transmission unusable. Methods for changing the transmission fluid: Loosen the nut at the bottom of the transmission oil pan to allow the old transmission fluid to drain naturally by gravity; connect the transmission to a circulation machine via pipeline interfaces, where the new transmission fluid will push out the old fluid under pressure; remove the oil pan for a fluid change.
