Description
This listing covers OEM part number A0305452632, a genuine Mercedes-Benz W163 ML-Class Automatic Transmission ECU, removed from a written-off vehicle and confirmed in working order before dispatch.
The transmission control unit manages the 5G-Tronic five-speed automatic gearbox in the W163 ML-Class, directing gear selection strategy across all driving conditions. It oversees torque converter lockup, sport and economy shift programme activation, and coordinates shift commands with the vehicle’s ESP and traction control systems to maintain stability under load.
Common symptoms of a failing transmission ECU in the W163 ML-Class include harsh or jerky gear changes that worsen at operating temperature, the gearbox becoming stuck in a single ratio, a transmission warning light appearing on the dashboard, and the automatic gearbox entering a fail-safe mode that restricts forward progress.
This is a genuine used and tested unit bearing OEM part number A0305452632. Professional installation by a qualified technician is required. A transmission TCU adaptation or basic settings reset must be carried out following installation to complete the repair.
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.
