Transmission Information

Transmission

The engine torque is transferred to the transmission via the flywheel. The transmission is built like a 7-speed 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.

Technical Data






ATF and transmission fluid (Manual Transmission Fluid)

The S-Tronic transmission works with separated oil chambers for the ATF and the transmission fluid (Manual Transmission Fluid).

ATF means "Automatic Transmission Fluid".

The transmission fluid for the S-Tronic transmission is also known as MTF. MTF means "Manual Transmission Fluid".

• Only the ATF available as a replacement part for the S-Tronic transmission may be used for the dual clutch with hydraulics. Refer to the Parts Catalog.

• Only the transmission fluid (MTF) for the S-Tronic transmission that is available as a replacement part may be used for the manual transmission, the front final drive and the transfer case. Refer to the Parts Catalog.

• Using other ATF or transmission fluids can result in malfunctions or transmission failure.

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.
