Fluid Function

Transmission fluid does not just >>lubricate<< the transmission.

Imagine: the transmission fluid also transports the finest differential abrasive parts in both filters. The fluid makes sure the lubricating film does not wear off the differential tooth flanks. At the same time, it acts as a switch valve pressure medium to enable it to perform its functions.

It also seals the selector lever and helps the synchronizer rings when shifting gears. The fluid conserves and transports warmth and minimizes noise. The fluid performs many functions. The Direct Shift Gearbox (DSG) transmission fluid fulfills many requirements.

To maintain this degree of performance, the filter on the transmission should be replaced during the oil maintenance service.
