Servicing the 7DCT300 Gearbox: Essential Maintenance

Introduced in 2018, the 7-speed Double Clutch Automatic Transmission (Getrag 7DCT300) is found in BMW’s and Mini’s with transverse mounted engines.

These are always front wheel drive or X-Drive (no 7DCT300 equipped vehicles are rear wheel drive). 

When Should the 7DCT300 Be Serviced?

BMW recommends servicing the 7DCT300 gearbox every 6 years or 70,000 miles, whichever comes first.

If this service is missed, your vehicle will issue a drivetrain warning on the dashboard indicating the need for immediate attention.

What Does a 7DCT300 Service Involve?

We specialise in servicing these DCT transmissions and ensure every detail is handled. Here’s what our service includes:

  1. Transmission Fluid Replacement
    Over time, the specialised transmission fluid in the 7DCT300 degrades, reducing its ability to lubricate and protect the gearbox components effectively. We use the correct, manufacturer-approved transmission fluid to ensure optimal performance and reliability.
  2. Clutch Re-Calibration
    A unique aspect of the 7DCT300 is its dual-clutch system, which requires precise calibration to operate correctly. As part of our servicing process, we re-calibrate the two clutches to ensure smooth gear shifts, prevent premature wear, and reduce the risk of further mechanical issues.
