Description
OEM part numbers 7512045 and 0260002642 identify a genuine used and tested automatic transmission ECU module from BMW, fitting E46 and E39 series models.
The TCM oversees gear selection, torque converter lockup, and the adaptive shift mapping that evolves with the driver’s individual driving style. Sport, Economy, and Winter shift programmes are managed by this module, which also governs kickdown logic for full-throttle acceleration and activates limp-home protection on fault detection. Continuous communication with the engine ECU ensures smooth and efficient power delivery.
A failing TCM may produce harsh or unpredictable gear changes, the gearbox locking into a single limp-home ratio (typically 3rd gear), slow or denied engagement of Drive or Reverse, loss of kickdown response, and transmission fault codes logged during a diagnostic scan of the vehicle.
This part is in good used condition, and OEM part numbers 7512045 and 0260002642 have been verified. Professional installation is recommended, along with adaptation or coding using BMW-compatible diagnostic tools 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.
