Application and compatibility

The presented gearbox is designed to work with the Diesel power unit in BMW F20 and F21 116d B37 models. This ensures consistency in drivetrain operating parameters, such as torque characteristics and power delivery to the wheels.

The automatic transmission in this model ensures smooth gear changes, which translates into stable acceleration, predictable vehicle behavior, and convenience in city traffic and on the road. The design is adapted to the specifics of a diesel engine, which promotes efficient use of the available torque.

Technical characteristics of the automatic gearbox

The Automatic type means that gear changes occur without driver intervention, using electronic and hydraulic control. The transmission selects gears based on load, speed, and driving style, which improves user comfort and allows you to focus on driving the vehicle.

Working with a diesel engine requires appropriately selected gear ratios and resistance to high torque. This gearbox is configured to provide:

• consistent acceleration across the entire rev range,
• stable operation at low engine speeds,
• comfortable gear changes without sudden jerks.

Condition, origin, and identification parameters

The item comes from the BMW offer and is classified as used, which allows you to combine original fitment with a more favorable purchase cost compared to a new transmission. The product has an assigned warehouse identifier in the form of SKU, as well as an OEM part number and available interchangeable numbers, which facilitates verification of compatibility with a specific vehicle configuration.

Brand affiliation is marked via the manufacturer parameter, and the current condition has been specified in the technical specification. Additionally, the product data details the fuel type and gearbox type, which allows for quick confirmation that the transmission is intended for a diesel unit and belongs to the automatic gearbox group.
