What is the oil change method for Volkswagen's wet dual-clutch transmission?

[Stevie]

The oil change method for Volkswagen's wet dual-clutch transmission is as follows: 1. Loosen the drain screw at the bottom of the transmission to drain the oil before refilling: When the engine is turned off and the automatic transmission stops working, the oil pump becomes stationary, halting the circulation of the automatic transmission oil. The oil flowing in the valve body, pistons, torque converter, radiator, and cooling lines also stops abruptly, preventing it from returning to the oil pan. 2. 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. 3. Use a circulation machine to change the automatic transmission oil: Dynamic oil change with an intelligent circulation machine can filter and clean sludge and impurities inside the automatic transmission through circulation; perform an equal exchange to ensure complete replacement of the old oil inside the transmission, thoroughly clean the internal circulation, and provide the transmission with a good internal working environment, thereby extending its lifespan.
