Description
OEM part numbers 1422388 and 0260002285 identify a genuine used and tested automatic transmission ECU module from BMW, sourced from E34 series vehicles.
The transmission control module directs gear selection, torque converter lockup, and adaptive shift mapping that learns the driver’s habits over time. Sport, Economy, and Winter programmes are managed by this module, alongside kickdown logic for full-throttle acceleration and automatic limp-home protection on fault detection. Data communication with the engine ECU supports smooth and responsive power delivery throughout all driving modes.
A malfunctioning TCM can cause harsh or erratic gear shifts, the gearbox defaulting to a single limp-home gear (typically 3rd), delayed or absent engagement of Drive or Reverse, loss of kickdown function under hard acceleration, and fault codes logged in the transmission control module address.
The unit is in good used condition with OEM part numbers 1422388 and 0260002285 confirmed. Professional installation is recommended, and post-fit adaptation or coding using BMW-compatible diagnostic equipment may be necessary. 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.
