01V, 5 SPD. A/T (AWD)

Notes for 5-speed automatic transmission 01V All Wheel Drive (AWD), 01V, 5 SPD. A/T (AWD)
180 5-Spd. Automatic Transmission 01V contains extensive information about the function of this transmission.

Torque converter
The torque converter is equipped with a slip controlled torque converter lockup clutch. The closing of the lock-up clutch is determined by the engine load and speed and produces very little vibration. The lock-up clutch drives all forward gears mechanically without slip.

Transmission
5-speed automatic transmission 01V AWD is equipped with 5 hydraulically activated forward gears. When the lock-up clutch is closed these forward gears bypass the torque converter slip and become mechanically driven gears.

Transmission Control Module (TCM) J217 with driving situation shifting (fuzzy logic)
Determining the driving situation and driving resistance dependent shift point occurs 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.

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

Guided Fault Finding, Vehicle Self-Diagnosis and Test Instruments
Before repair work is performed on the automatic transmission, the fault cause should be determined as accurately as possible using diagnostic operation system VAS5051 A in modes of operation "Guided Fault Finding", "Vehicle Self Diagnosis" and "Test Instruments".
