Description
OEM part numbers 5WK33213K01 and 01N927733BQ identify a genuine used and tested automatic transmission ECU module from Audi, designed for the A4 B5 model series.
The TCM oversees gear selection, torque converter lockup, and the adaptive shift mapping that continuously adjusts to the driver’s behaviour and road conditions. Sport, Economy, and Winter shift programmes are controlled by this module, as is kickdown logic for full-throttle acceleration and automatic limp-home protection on fault detection. Close communication with the engine ECU ensures efficient and smooth power delivery at all times.
A failing TCM typically produces harsh or unpredictable gear changes, the transmission defaulting to a single limp-home gear ratio (usually 3rd), slow or refused engagement of Drive or Reverse, loss of kickdown response, and fault codes recorded in the transmission control module diagnostic address.
The unit is in good used condition with OEM part numbers 5WK33213K01 and 01N927733BQ confirmed. Professional installation is strongly advised, and coding or adaptation with Audi-compatible diagnostic equipment may be necessary after fitting. A 14-day return period applies.
Returns accepted only for genuine faults — faulty on arrival, not as described, or wrong part supplied — requested within 14 days, with all 3 anti-tamper stickers intact. No returns for change of mind, incorrect installation, coding/programming, or buyer compatibility errors; checking compatibility (OEM number, firmware, vehicle) is the buyer’s responsibility.
