The DSG valve body is definitely one of the simplest we have seen in transmissions (see figures 1 through 5). It contains only five valve line-ups, two checkballs, three damper assemblies, two pressure senders (pressure sensors/transducers) and 13 filters (see figures 2, 3 and 5).

Although the DSG 02E transmission contains 11 solenoids, they could be placed into three categories: gear actuator, pressure control and TCC. This article covers the first group and part of the second, and next month’s article will cover the rest of the second group and the third.
The Direct Shift Gearbox Part 2
Housed inside the six-speed direct-shift gearbox (DSG) is a Mechatronics assembly consisting of a control module, valve body and solenoids (see figures 1 and 2).

Volkswagen’s direct-shift gearbox DSG 02E (see Figure 1) is used in the United States in some 2004-to-present New Beetle, New Jetta and Golf GTI models. It is a six-speed manual front-wheel-drive gearbox that is shifted automatically.
