We carry out everything from simple repairs to a complete overhaul of your automatic transmission.

What we specialize in are automatic transmissions for US cars, both in terms of renovation and sales of spare parts.

Of course, we also take on newer gearboxes as the workshop is often filled with Mercedes, Volkswagen and various other gearboxes on the market.

We offer personal service and advice, so do not hesitate to call or email if you have questions about renovation or purchasing spare parts.

If you are looking for a replacement gearbox, we can also offer this to some extent, contact us for further information.


Some of our favorites when it comes to automatic transmissions: Powerglide, Hydramatic, Dynaflow, Jetaway, Turbo Hydramatic 400, Turbo Hydramatic 350, Fordomatic, Cruiseomatic C4-C6, Torqueflite.
