How to choose a transmission control unit
The transmission control unit (TCU) manages gear changes in an automatic or automated gearbox. It depends on the gearbox type, the engine and the software version, so two cars of the same model can have different control units. Compare the number on the unit's housing and the gearbox marking.

What to watch out for
A used control unit may hold the data of the previous car, so adaptation or coding can be needed after the replacement. The scope depends on the specific model and gearbox, so ask us before you buy.
Frequently asked questions
| Is the car model enough to choose the right part? | No. The same model can have different versions of a part depending on engine, equipment and year. The number on the label or in the listing is what counts. |
|---|---|
| Does the part come with a warranty? | Yes, used parts come with a 6-month warranty. The terms are given in the listing and on the returns, warranty and complaints page. |
| What should I send so you can check the fit? | A photo of the label or housing of the part with the numbers visible, plus the car's make, model, year and engine. With that we check whether we have a matching version. |
