Description
OEM part numbers 1421453 and 0260002282 identify a genuine used and tested automatic transmission ECU module from BMW, compatible with both E36 and E34 series vehicles.
The transmission control module governs gear selection, torque converter lockup, and the adaptive shift mapping that continuously adjusts to the driver’s habits and driving conditions. Sport, Economy, and Winter shift programmes are all controlled by this module, along with kickdown logic for full-throttle acceleration and automatic limp-home protection when a fault occurs. The TCM maintains constant communication with the engine ECU to support smooth and dependable power delivery.
Signs of a failing TCM include harsh or erratic gear changes, the transmission defaulting to a single limp-home ratio (typically 3rd gear), delayed or refused engagement of Drive or Reverse, lost kickdown response under hard acceleration, and fault codes stored in the transmission control module diagnostic address.
This part is in good used condition with OEM part numbers 1421453 and 0260002282 confirmed. Professional fitting is recommended, and post-fit adaptation or coding with BMW-compatible diagnostic tools may be required. 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.
