Servicing of Mini 7 Speed Steptronic Automatic Transmission with Double Clutch (Getrag 7DCT300)

Starting in 2018 Mini started to fit in some models the 7 Speed Double Clutch Automatic Transmission, this transmission has a maximum recommended service interval of 6 years or 70,000 miles (whichever comes first). As soon as this service is due you will get a drivetrain warning on your Mini Dashboard Display, it is important that as soon as this happens you make arrangements to have the transmission serviced, as if you exceed the service interval by more than 2,000 miles you will get a warning for clutch replacement!

We service these transmissions regularly and hold in stock the correct transmission fluid and genuine replacement filler and drain caps, part of the service is the re-calibration of the 2 clutches in the transmission to ensure correct operation and avoid the possibility of damage.

Mini R50/52 5 to 6 Speed Gearbox Conversion

As the first generation R-Series (R50/R52 Cooper/One) cars age, it is becoming increasingly more common for the Midlands and Getrag 5-Speed gearboxes to fail. We have developed a conversion kit using the higher specification 6-Speed Getrag gearbox taken from the R53 Cooper S model.

The Kit includes a 6-Speed Gearbox, shifter box with cables, starter motor, driveshafts, flywheel, clutch and all necessary mounts and bolts to complete the conversion giving you better gear ratios when on the motorway, better fuel economy and the added reliability of the 6-Speed Getrag which has a very low failure rate, even when running with a lot more power in the Cooper S.

We offer this kit as a full supply and install option.

R53 Eaton M45 Supercharger Servicing

We offer a full removal, inspection and oil service for the Eaton M45 Supercharger found on R52/R53 first generation Mini Cooper S and JCW models.
Mini doesn't have a recommended service interval for the M45 superchargers but we have seen chargers with as little as 70k miles running dry and causing irreversible damage to the PTO gears on the water pump side. If you don't have a receipt for a supercharger service, we strongly advise booking in for one as soon as possible.
During the service, we remove both ends of the supercharger housing to inspect the gears for wear caused by potential oil starvation/degradation as well as examining the bearings for slop/play.
Once we are happy with the condition of the supercharger, the oil is replaced with an oil exceeding all OEM specifications and the charger is re-fitted to the car using new gaskets and BMW Green seal. Our recommendation for supercharger service is every 50k miles. It is also worth considering replacing the waterpump at the same time as the supercharger service.

We can also install a performance supercharger pulley whilst doing the service, please ask for details.
