Purpose and technical specifications

The presented automatic gearbox is dedicated to BMW F90 M5 and F91 M8 models with petrol engines. It belongs to the Automatic Gearboxes category, which means full integration with the vehicle's factory control systems, driving modes, and electronic safety features. The automatic design ensures smooth gear changes, optimized for high torque and dynamic driving.

As an OEM component, the gearbox works with the original control unit software, traction control systems, and safety features, minimizing the risk of communication errors within the vehicle's bus. Using the correct type of transmission in high-performance cars is crucial for the durability of the entire drivetrain.

Compatibility and OEM selection

The selection of this gearbox should be based on verification via the OEM number and interchangeable part numbers, as well as vehicle data (VIN). This identification method helps avoid mechanical and electronic compatibility issues, especially in advanced M5 and M8 models. In case of doubt, consultation with a mechanic or a specialist in BMW automatic transmissions is recommended to confirm compatibility with your specific car configuration.

A used gearbox from this product group is a good solution for major failures where rebuilding the existing unit is uneconomical or technically difficult. A properly selected component allows for restoring correct drivetrain operation at a reasonable cost.

Condition, installation, and service recommendations

The offered automatic gearbox is a used component, which in practice means it must be installed in accordance with the service procedures provided for BMW automatic transmissions. It is recommended to check the oil cooling system, verify the lines, and use the appropriate type of transmission fluid consistent with the vehicle manufacturer's specifications. This approach reduces the risk of overheating and extends the service life of the component.

Professional installation also includes gearbox adaptation in the control unit and any necessary calibration procedures. In the case of M5 and M8 models, this has a direct impact on shift quality, response time, and interaction with sport and comfort modes.
