Descrizione
OEM part number 7521759 is a genuine used and tested automatic transmission ECU module from BMW, compatible with E46 and E39 series vehicles.
The TCM governs gear selection, torque converter lockup, and adaptive shift mapping that learns the driver’s individual style. It manages Sport, Economy, and Winter shift programmes, controls kickdown logic for full-throttle acceleration, and activates limp-home protection on fault detection. The module communicates continuously with the engine ECU to deliver smooth and efficient power across all driving conditions.
Common failure symptoms include harsh or erratic gear changes, the gearbox locking into a single limp-home ratio (typically 3rd gear), delayed or refused engagement of Drive or Reverse, absence of kickdown response, and fault codes logged under the transmission control module address.
This unit is in good used condition with OEM part number 7521759 verified. Professional installation is recommended, and post-fit adaptation or coding using 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.
