Purpose and compatibility

The presented BMW automatic gearbox has been designed to work with the N57S unit in the 40dX version and the xDrive all-wheel-drive system in X5 E70 LCI and E71 bodies. The GA8HP70X design ensures sufficient durability for the engine's high torque while maintaining the refinement expected in the premium SUV segment.

Its original BMW group origin ensures the correct geometry, mounting points, and control system interfaces, which facilitates installation and reduces the risk of electrical and mechanical compatibility issues.

Technical and functional characteristics

The gearbox belongs to the Automatic gearboxes category and is constructed as a fully automatic transmission, adapted for dynamic driving and comfortable daily use. The applied automatic transmission concept enables:

• efficient transfer of the N57S engine's high torque,
• smooth gear changes during acceleration and engine braking,
• stable cooperation with the xDrive system in urban and highway conditions.

Thanks to its factory configuration, the gearbox works with BMW vehicle control systems, which allows for maintaining the manufacturer-intended driving modes and gear-shifting logic.

Benefits of using an original BMW automatic gearbox

Choosing an original BMW automatic gearbox for the X5 E70 LCI / E71 40dX N57S is a solution that allows you to maintain the consistency of the entire drivetrain. Using a transmission that complies with factory specifications:

• reduces the risk of improper xDrive system operation,
• facilitates future diagnostics and service,
• ensures predictable vehicle behavior under various load conditions.

This is particularly important in high-power vehicles, where precise cooperation between the engine, gearbox, and drivetrain has a direct impact on durability and operational safety.

Condition, origin, and service aspects

The offered gearbox comes from the BMW group and is a used item, which represents an attractive cost alternative to new components. For workshops and individual users, this means the possibility of carrying out repairs based on an original component while maintaining a reasonable service budget.

Before installation, standard service procedures typical for automatic transmissions are recommended, such as checking the oil cooling system, verifying wiring harnesses, and preparing the vehicle for gearbox adaptation in the BMW diagnostic system, in accordance with the manufacturer's procedures.
