Technical specifications and intended use

The presented gearbox belongs to the Manual gearboxes category, which means classic, mechanical gear shifting using a clutch. It has been designed specifically for use with BMW powertrains in E90 LCI, F10, and F20 versions, with consideration for integration with the vehicle's start/stop system.

The manual design of the transmission ensures direct torque transfer, and properly selected gear ratios allow for maintaining appropriate dynamics while keeping fuel consumption reasonable. Using an original gearbox dedicated to specific models minimizes the risk of installation issues and communication problems with the vehicle's electronics.

Start/stop system and vehicle integration

The version of the gearbox with the start/stop function is adapted to work with the factory automatic engine start/stop system. The appropriate design of the transmission and its control allows for:

• correct gear position detection by the vehicle's system,
• stable re-engagement of the drive after the engine starts,
• maintaining comfort when starting off without jerking resulting from improper interaction between the gearbox and electronics.

Thanks to this, the driver retains full functionality of the start/stop system while enjoying the benefits of manual gear shifting.

Benefits of using an original BMW manual gearbox

Using an original gearbox in a BMW E90 LCI, F10, or F20 allows for maintaining the consistency of the entire drivetrain. Key advantages include:

• Factory fitment – the transmission is designed for specific models, which facilitates installation and limits the need for modifying additional components.
• Consistent operation with electronics – correct cooperation with the start/stop system and other control modules.
• Predictable handling characteristics – maintaining the BMW-signature way of building torque at the wheels and response to gear changes.

Such a solution is particularly beneficial for repairs where maintaining original driving parameters and vehicle operating comfort is a priority.

Condition, verification, and selection of the gearbox

The offered gearbox is used, which allows for significantly reducing repair costs compared to new components while maintaining the original BMW design. Before installation, it is recommended to perform a standard inspection of wear items and seals in accordance with the service procedures of the manufacturer or a workshop specializing in the BMW brand.

To select the correct transmission for a specific vehicle, it is worth using the OEM number and interchangeable numbers, as well as vehicle data (model, production year, engine type). This helps to avoid mechanical and electronic compatibility issues.
