Description
OEM part numbers 7506450 and 0260002717 identify a genuine used and tested automatic transmission ECU module from BMW, compatible with E53 X5 and E70 X5 model series vehicles.
The TCM is responsible for gear selection, torque converter lockup, and adaptive shift mapping that learns and adapts to the driver’s behaviour over time. It manages Sport, Economy, and Winter programmes and controls kickdown logic for full-throttle acceleration demands. Limp-home mode activates automatically on fault detection, and the module maintains constant communication with the engine ECU for coordinated power delivery.
TCM faults commonly present as harsh or jerky gear shifts, the transmission locking into a single limp-home ratio (generally 3rd gear), delayed or denied engagement of Drive or Reverse, absence of kickdown function, and fault codes stored under the transmission control module address in vehicle diagnostics.
This unit is in good used condition with OEM part numbers 7506450 and 0260002717 verified. Professional installation is recommended, and adaptation or coding via BMW-compatible diagnostic equipment will likely be required 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.
