Transmission

The DSG transmission 02E is also called "S-Tronic Transmission" double clutch transmission, it is constructed like a 6-speed manual transmission. The engine torque is transferred to the transmission via the dual-mass flywheel. It is operated like an automatic transmission by both multi-plate clutches that are hydraulically activated. The gears are automatically engaged or can be manually engaged in the Tiptronic position. Clutch pedal is not available.

Selector Mechanism

The parking lock is mechanically engaged by the selector lever cable only in "P". The remaining selector lever positions and shift functions are transmitted to the Direct Shift Gearbox (DSG) Transmission Mechatronic (J743) from the selector lever (E313) in the shift mechanism via the CAN bus.

Gear Oil and Axle Oil

The direct shift automatic transmission and front final drive have a shared gear oil fill. Refer to => [ Transmission Fluid, Checking and Filling ] Transmission Fluid, Checking and Filling.

• Only the gear oil available as a replacement part may be used for the 02E direct shift automatic transmission. Other transmission fluids can cause malfunctions or transmission failure. For the correct part number, always refer to the Electronic Parts Catalog (ETKA).

The bevel box has a separate axle oil fill. Refer to => [ Axle Oil Level, Checking and Filling ] Axle Oil Level, Checking and Filling.

• Only the axle oil available as a replacement part may be used with the bevel box. Other fluids can cause malfunctions or bevel box failure. For the correct part number, always refer to the Electronic Parts Catalog (ETKA).

Disposal Regulations for Oils and Fluids

Dispose of drained oil properly.

• Disposing of used oils and fluids improperly endangers the environment.

• Mixing with solvents, brake fluid and coolant is not permitted.

• Observe information on oil the packaging.

Shift Point Changes on Inclines and Declines

An additional gear change map automatically selects the gear changes for gradients dependent upon accelerator pedal position and driving speed.

• The gear change map for extreme inclines is matched to engine output.

• The gear change map for extreme declines is matched to the engine braking action.

• By selecting a gear directly in Tiptronic mode, the engine braking effect can be used with a specific gear engage, for example when driving downhill with a trailer.
