Descrizione
I numeri di parte originali 1423642 e 0260002429 identificano un modulo centralina cambio automatico originale usato e testato da BMW, compatible with E46, E38, and E39 model series vehicles.
This transmission control module manages gear selection, torque converter lockup, and the adaptive shift mapping that refines itself to match the driver’s habits. It governs Sport, Economy, and Winter shift programmes alongside kickdown logic for performance acceleration, and initiates limp-home protection whenever a fault is detected. The TCM communicates closely with the engine ECU to maintain smooth, coordinated power delivery at all times.
Symptoms associated with a failing TCM include harsh or erratic gear shifts, the transmission locking into a single limp-home ratio (typically 3rd gear), delayed or refused engagement of Drive or Reverse, missing kickdown response under hard acceleration, and fault codes stored under the transmission control module address.
The unit is in good used condition with OEM part numbers 1423642 and 0260002429 confirmed. Professional installation is advised, and post-fit adaptation or coding with BMW diagnostic equipment is likely required. A 14-day return period applies.
