Overhaul gearboxes


About Michael

It all started with my first car in 1993, a 1982 BMW e21 323i with a manual 4-speed gearbox, this one that made a lot of RPM (Rounds per minute) on the highway. My first key experience was a conversion to manual 5 speed, this what a great deal improvement was now I could enjoy my BMW even more

From this hobby and passion for the older BMWs from the 60’s, 70’s and 80’s in particular, we have grown to where we now specialize in overhauling, in particular, oldtimer BMW gearboxes and differentials, actually the drivetrain of the car.

Complete conversion automatic gearbox

Do you have enough of your three-speed automatic gearbox and do you want a more friendly transmission with lower rpm and smoother shifting, which is a lot nicer and therefore you will enjoy your car even more.

This also makes your BMW drive more economically and it is better for the engine, which now has much less wear because it will now run a lot less rpm. Especially nice for the LPG drivers among us. Because these older BMWs have a mechanical odometer drive in the three-speed automatic transmission.

We will convert this kilometer indication to electronic. An electronic odometer clock will then be installed in your existing original cockpit. You will keep the original odometer plate so you won’t notice that there is an electronic odometer behind it, so it will keep its original appearance. This is a complete conversion from 3-speed automatic gearbox to a 4-speed automatic gearbox, for all M10 M20 and M30 engines.

From manual to 4-speed automatic transmission is of course also possible. And conversion from 4-speed to 5-speed is also possible. If you are interested, contact us for all your questions.
