Does the Volkswagen Dry Dual-Clutch Transmission Require Transmission Fluid Replacement?
2 Answers
Volkswagen dry dual-clutch transmissions do require fluid replacement. Here are some details about Volkswagen transmissions: 1. Essentially, Volkswagen's DSG dual-clutch automatic transmission is a manual transmission equipped with dual clutch plates and a shift mechanism. Compared to AT transmissions, the transmission fluid can be replaced relatively later. 2. In a sealed transmission, automatic transmission fluid not only serves a lubricating function but also provides the necessary oil pressure for the operation of the DSG's shift valve body and the AT transmission's torque converter. Contamination or deterioration of the transmission fluid can lead to unstable oil pressure, and prolonged driving under such conditions can cause damage to the transmission.
As someone who has studied cars for many years, I understand the design characteristics of Volkswagen's dry dual-clutch transmission. The dry clutch is not immersed in oil, as the oil is primarily used to lubricate the gear system. Therefore, Volkswagen generally classifies it as a maintenance-free type, unlike wet dual-clutch transmissions that require regular oil changes. The user manual is key—it may sometimes specify checking the oil condition under extreme driving conditions or high mileage, but blindly changing the oil could lead to contamination or sealing issues, increasing the risk of failure. During routine maintenance, simply having the technician visually inspect the oil level is sufficient—don’t proactively request an oil change. If you drive frequently or take long trips and notice rough shifting or unusual noises, then it’s worth a professional evaluation to avoid unnecessary expenses and complications.
