This approach minimizes the risk of incorrect fitment and facilitates installation in place of the original transmission.

Thanks to factory markings, it is possible to precisely match the gearbox to a specific equipment version, which is important for both the correct operation of the drivetrain and communication with the vehicle's electronics.

Installation and maintenance recommendations

When replacing the transmission, it is recommended to perform a full service procedure: checking the gearbox oil cooling system, verifying the condition of the mounts, and properly bleeding the system. Proper filling and selection of oil compliant with the manufacturer's specifications are crucial for the durability and refinement of the automatic transmission.

To ensure long-term, stable operation, it is worth performing a gearbox adaptation in the vehicle's controller after installation, in accordance with diagnostic procedures used in service centers specializing in the BMW brand.
