Transmission

The 5-speed automatic transmission 01V has five hydraulically activated forward gears. When the lock-up clutch is closed these forward gears become mechanically driven gears by cutting out the torque converter slip.

Control module -J217- with driving situation gear changes (Fuzzy Logic)
Determining the driving situation and driving resistance dependent gear change point happens automatically.
Advantages:
- Gear changes will be consumption orientated
- Maximum engine output is always available
- Individual adaption of gear change points in all driving situations
- Gear change points are infinitely variable

Gear change point variations for gradients
An additional gear change map automatically selects gear changes for gradients dependent upon accelerator pedal position and driving speed.
- Gear change map for extreme uphill stretches is matched to engine output
- Gear change map for extreme downhill stretches is matched to the braking effect of the engine
