Description
This is a used original Opel automatic transmission control unit for Opel Astra G, manufactured by Aisin. The primary OEM number is 90560073, with hardware reference LW001210. It is the gearbox ECU/TCU that manages communication and control within the automatic transmission system for the stated model.
Its job is to process signals from the vehicle and transmission, then command shift timing, gear engagement and overall transmission operation. A properly working TCU helps the automatic gearbox deliver smooth shifting, stable driveability and consistent response under changing road conditions.
Common signs of a faulty unit include harsh or delayed shifting, incorrect gear selection, transmission warning lights, limp-home mode, hesitation when engaging drive or reverse, or intermittent gearbox communication faults. Electrical issues within the control unit can also contribute to erratic shift behaviour and poor automatic transmission performance.
This is a used original part, removed from a vehicle and tested before sale. Please match 90560073 and LW001210 exactly before ordering. Professional installation is recommended, and coding, programming or adaptation may be required depending on the vehicle and transmission setup.
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.
