General 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
| Manufacturer identification | DL501-7Q |
| Transmission code | 0B5 |
| Transmission name | S tronic |
| Weight | Approximately 142 kg (with flywheel, ATF and filled with transmission fluid) |
ATF and Transmission Fluid (Manual Transmission Fluid)
The S tronic transmission 0B5 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 0B5 is also known as MTF. MTF means "Manual Transmission Fluid".
- Only the ATF available as a replacement part for the S tronic transmission 0B5 may be used for the dual clutch with hydraulics.
- Only the transmission fluid (MTF) for the S tronic transmission 0B5 that is available as a replacement part may be used for the gear set, the front final drive and the transfer case.
- 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.
