Purpose and compatibility

The presented empty gearbox version is dedicated to BMW E81, E87, E90, and E91 LCI vehicles with the N43 unit in 116i, 118i, and 318i variants. The housing design retains factory mounting points for the engine, drivetrain, and suspension components, which helps maintain the proper rigidity of the powertrain and ensures correct cooperation with other drivetrain components.

Using an original housing makes it possible to recreate the configuration intended by the manufacturer, which facilitates subsequent calibration and diagnostics of the drivetrain at a service center. This solution is particularly beneficial for post-accident repairs or when reconstructing a gearbox after a major mechanical failure.

Technical characteristics of the automatic gearbox housing

This is an empty automatic gearbox housing, which means that internal mechanical and hydraulic components must be selected and installed separately. This configuration allows specialized workshops to individually assemble the transmission using new or refurbished components while maintaining the original shape and external dimensions.

The automatic transmission type ensures smooth gear shifting once the interior is properly assembled, and the factory housing serves as a key load-bearing element for the entire system. Maintaining the proper rigidity and geometry of the casing has a direct impact on the durability of the bearings, correct shaft guidance, and stable operation of the hydraulic control system.

Application in the steering and drivetrain system

The product belongs to the Steering gears and housings category, which emphasizes its role as a structural element working with the drivetrain and mounts in the front part of the vehicle. A properly selected gearbox housing influences:

• correct positioning of the powertrain relative to the steering gear and suspension,
• maintenance of the proper geometry of auxiliary component mounts,
• stable operation of the drivetrain under various loads.

For workshops specializing in the BMW brand, using an original automatic gearbox housing is a practical solution for reconstructing a transmission after mechanical damage, such as casing cracks or deformations following a collision.

Benefits of using a used OEM housing

Choosing a used automatic gearbox housing for a BMW allows for optimized repair costs while maintaining the factory design. The original casing ensures compatibility with factory mounting points, which facilitates installation and reduces the risk of fitment issues. For professional service centers, this is a beneficial base for building a complete transmission using new consumables.

A used element of this type is particularly suitable for projects where maintaining compliance with the manufacturer's technical documentation is crucial, while also being important to limit costs compared to purchasing a new, complete gearbox. This allows for flexible selection of the transmission interior configuration to suit specific applications and user expectations.
