Notes on 5-Speed Automatic Transmission 01V

Notes on 5-speed automatic transmission 01V, 01V, 5 Spd. A/T AWD
Self-study program number. 180 informs extensively about the function of this transmission.

Torque converter
The torque converter is equipped with a lock-up clutch. The lock-up clutch is closed load- and speed-dependant with minimum pulsations and mechanically drives all forward gears independent of slip.

Transmission
5-speed automatic transmission 01V is equipped with 5 hydraulically activated forward gears. By passing the torque converter slip, these forward gears become mechanically driven gears if the lock-up clutch is closed.

On Board Diagnostic (OBD)
Before performing service work on the automatic transmission, cause of damage must be exactly determined via "Guided Fault Finding".

"Guided Fault Finding is performed using the VAS5051 tester.

Transmission Control Module (TCM) -J217- with driving situation shifting (fuzzy logic)

Driving situation- and driving resistance dependent shift point determination is performed automatically.

Advantages:
^ it is shifted depending on consumption
^ highest engine performance is always available
^ individual adaptation of shift points in all driving situations
^ Arbitrarily changed shift points

Shift point change when driving up- or downhill ranges
At uphill or downhill ranges, the shifts are automatically selected dependent on the accelerator pedal position and vehicle speed via additional shift characteristics maps.
^ Shift characteristics map for extreme uphill driving is adapted to the engine performance.
^ Shift characteristics map for extreme downhill driving is adapted to the braking effect of the engine.
