Transmission Control Modules and Actuators

We test, repair and exchange an extensive range of transmission Electronic Control Modules including, Clutch Actuators, Gear Selectors, DSG Mechatronics and CVT control units. All transmission systems are fully tested on our HIL (Hardware-In-the-Loop) vehicle test systems, this ensures that every transmission control unit that we rebuild meets or exceeds OE specifications. 

Below is a small list of the most common failing transmission control modules that we cover.

If you do not see your transmission unit listed then please see our product catalogue for our full range.
