OEM part numbers 1422770 and 0260002359 identify a genuine used and tested automatic transmission ECU module from BMW, designed for E38 and E39 series models.
The TCM controls gear selection, torque converter lockup, and adaptive shift mapping that adjusts to the driver’s style across varying driving conditions. Sport, Economy, and Winter shift programmes are coordinated by this module, as is kickdown logic for full-throttle acceleration. Limp-home protection engages automatically when a fault is detected, while continuous data exchange with the engine ECU ensures smooth power delivery.
Common TCM failure symptoms include harsh or erratic gear changes, the gearbox defaulting to a single limp-home ratio (typically 3rd gear), delayed or refused engagement of Drive or Reverse, loss of kickdown response, and transmission fault codes stored in the vehicle’s diagnostic system.
This unit is in good used condition with OEM part numbers 1422770 and 0260002359 verified. Professional installation is recommended, and post-fit adaptation or coding with BMW-compatible diagnostic equipment 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.
