How often should the automatic transmission fluid be changed for the 2017 Passat?

[MacSarah]

For the 2017 Passat, it is generally recommended to change the automatic transmission fluid every two years or approximately 40,000 kilometers. Signs that indicate the need for a transmission fluid change include vehicle shaking, gear shifting hesitation, transmission overheating warnings on the dashboard, engine stalling, and unusual noises. Hazards of not changing the transmission fluid for an extended period: Damage to the transmission's shift control mechanism; abnormal wear of gears and clutch plates inside the transmission; impaired transmission operation, leading to damage of the transmission valve body. The methods for changing transmission fluid are as follows: Loosen the drain screw at the bottom of the transmission to drain the old fluid before refilling. Remove the transmission oil pan directly for draining and refilling: This method is more thorough than the previous one, as it removes impurities from the bottom of the oil pan. Using a circulation machine to change the automatic transmission fluid: A smart circulation machine performs dynamic fluid replacement, filtering and cleaning out sludge and impurities from the automatic transmission.
