Purpose and compatibility

The presented automatic gearbox has been designed to work with the B58 petrol engine in BMW M140i and 340i versions of the F20 and F30 LCI generations. It is an OEM solution that maintains the factory operating parameters of the drivetrain, including shift characteristics, control logic, and integration with the vehicle's onboard systems.

By using this transmission, it is possible to maintain the consistency of the entire drivetrain, which is important both for post-accident repairs and when replacing a worn-out gearbox in cars used dynamically.

Technical and functional characteristics

The automatic design of the GA8HP50Z gearbox ensures comfortable vehicle operation in city traffic and on the road, without the need for manual gear changes. Using a transmission adapted to a petrol engine allows for optimal use of the torque and power of the B58 unit, which translates into efficient acceleration and stable maintenance of engine speed.

Key advantages of this gearbox include:

• smooth gear shifting under various engine loads,
• consistent cooperation with the vehicle's control electronics,
• ability to operate in comfort and dynamic modes (depending on the car's configuration),
• preservation of the factory driving characteristics typical for M140i and 340i models.

A drivetrain configured in this way allows for a predictable throttle response, which is important both in everyday use and during more dynamic driving.

Application in BMW petrol vehicles

The gearbox has been developed for use with petrol engines, which means that the gear ratios and shift logic are matched to the characteristics of the B58 unit. In practice, this translates into:

• efficient use of the engine's RPM range,
• reduction of unnecessary gear changes during relaxed driving,
• efficient downshifts when overtaking and accelerating.

As a result, the driver receives a drivetrain that retains the properties known from the factory BMW configuration, without compromising on comfort and dynamics.

Condition, origin, and benefits of installation

The offered gearbox belongs to the BMW automatic gearboxes group in used condition, which allows for economical vehicle repair while maintaining the manufacturer's original specifications. Choosing an OEM transmission from the same design family minimizes the risk of fitment issues and also facilitates the installation process and subsequent diagnostics.

The main benefits of using this gearbox include:

• preservation of factory integration with vehicle systems (e.g., engine control unit and safety systems),
• possibility of using the existing software configuration in the vehicle,
• reduction of vehicle downtime due to matching the specific generation and engine version.

Technical support and additional information

Before purchasing, it is worth verifying the compatibility of the gearbox with the specific vehicle configuration using the OEM part number and interchangeable numbers available in the technical specification. This helps avoid compatibility issues and speeds up the process of selecting the right component.

If you are planning a comprehensive repair or upgrade of the drivetrain area in your BMW and need other elements from the same group, such as a torque converter, control elements, or additional transmission components, check the available parts in the BMW automatic gearboxes category.

To better prepare for purchasing a used transmission and to learn about typical signs of wear and differences between individual types of gearboxes, it is worth reading the guide: Gearbox: manual, automatic or DSG – typical faults and a guide to buying a used gearbox. This will make it easier for you to assess which parameters and technical aspects are crucial when choosing the right automatic gearbox for your BMW.
