Product Description
Rover 75/MG ZT Transmission - Auto
On 1800 cc NA, V6 and diesel models the automatic gearbox was different on cars with a VIN prior to YM143049 but at some point MG Rover superceded the units to the post YM143050 gearbox. That change also meant the ECU had to be changed to the later type so if it is just a replacement ECU required please check the label on the ECU to identify whether the car still has the original early unit or has been changed to the later unit.
1800cc Turbo models were not affected.
