Description
OEM part number 7514365, a genuine BMW Automatic Transmission ECU compatible with the E46 3-Series and E39 5-Series, removed from a written-off vehicle and tested in working condition before dispatch.
This TCU manages the ZF 5HP five-speed automatic gearbox fitted to the BMW E46 3-Series and E39 5-Series, controlling gear selection strategy, upshift and downshift speed thresholds, and torque converter lockup behaviour. The module processes inputs from the throttle position sensor, output shaft speed sensor and engine control unit to execute smooth ratio changes, delivering precise kickdown response when the accelerator pedal is pressed to the floor.
Symptoms of a failing transmission ECU in the E46 or E39 include harsh, clunking gear changes under acceleration load, the ZF automatic gearbox becoming stuck in a single gear that the selector cannot override, an EML or transmission warning indicator appearing on the instrument cluster, and a complete loss of kickdown response when attempting to accelerate rapidly.
This is a genuine used and tested unit with OEM part number 7514365. Professional installation by a qualified technician is required. A transmission TCU adaptation or basic settings reset must be performed following installation to complete the repair and restore correct ZF gearbox operation.
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.
