Transmission

The DSG transmission 02E is also called a double-clutch transmission. The engine torque is transferred to the transmission via the dual-mass flywheel. The transmission is built like a 6-gear manual transmission. The alternating hydraulic actuation of the two wet multi-plate clutches permits operation similar to that of an automatic transmission. The gears are engaged automatically or manually with the Tiptronic mode. Clutch pedal is not available. More information 951403 The direct manual transmission 02E.

Selector Mechanism

In contrast to the automatic transmission, the selector lever position is no longer transmitted mechanically to the transmission via the selector lever cable and multi-function transmission range (driving range sensor). Selector lever positions and shifts are transmitted via a separate control module in the selector mechanism to the transmission control module via the CAN-Bus. The shifter occurs without a cable. Only in selector lever position P is the parking lock engaged mechanically via the selector lever cable.

Transmission Fluid

The transmission fluid levels inside the transmission and inside the front final drive are checked and filled at the same time. Refer to => [ Transmission Fluid, Checking and Filling ] Transmission Fluid, Checking and Filling.

• Exclusive use is to be made for the direct-shift gearbox 02E of the transmission fluid available from the parts list. Using other oils can lead to function problems or can even cause the transmission to fail, for the specification, refer to the Parts Catalog.

Oil level in bevel box is checked and filled separately. Refer to => [ Oil Level in Bevel Box, Checking and Topping Off ] Oil Level In Bevel Box, Checking and Topping Off.

• Only the gear oil available as a replacement part may be used for the bevel box. Using other oils can lead to function problems or can even cause the bevel box to fail, for the specification, refer to the Parts Catalog.

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 uphill stretches is matched to engine output

• The gear change map for extreme downhill stretches is matched to the braking effect of the engine.

• Direct gear selection by way of the Tiptronic function permits utilization of engine braking action with a specific gear engaged, for example, on a downhill gradient with a trailer.
