Purpose and technical specifications

The presented automatic gearbox has been designed to work with the diesel engine in BMW 1 and 2 series models, where stable operating parameters, appropriate gear ratios, and efficient torque management are crucial. The Automatic design ensures comfortable gear shifting, reducing jerking and improving driving refinement in both city traffic and on the highway.

The system designed for Diesel fuel faces different loads than petrol versions, which is why choosing the right gearbox is important both in terms of durability and proper cooperation with the vehicle's electronics. The applied transmission configuration is widely used in the BMW range, which facilitates servicing and access to technical documentation.

Benefits of using an automatic gearbox

The automatic transmission in this BMW model translates into significantly higher user comfort, especially in heavy city traffic. From the driver's perspective, this means:

• smooth, predictable gear shifting without the need to operate a clutch,
• better utilization of the diesel engine's torque characteristics,
• stable acceleration and downshifting when overtaking,
• optimized fuel consumption compared to some older automatic designs.

For workshops and users, it is also important that gearboxes from this family are well-recognized on the market, which facilitates diagnostics, selection of transmission oil, and planning of service maintenance.

Condition, verification, and vehicle selection

This item comes from the used BMW automatic gearboxes segment, which allows for a significant reduction in repair costs compared to purchasing a brand-new transmission. Before installation, a standard workshop procedure is recommended: checking for leaks, verifying mounting points, inspecting connectors, and replacing the oil and filter in accordance with the vehicle manufacturer's recommendations.

To correctly select the gearbox for a specific car, it is worth using the OEM number or interchangeable numbers as well as vehicle data (model, year, engine type). This minimizes the risk of incompatibility with the electrical harness, controller software, and final gear ratios.
