Purpose and technical characteristics

The offered automatic gearbox has been designed to work with petrol-powered engines, ensuring proper gear ratio alignment with the torque characteristics of these engines. The automatic design is responsible for smooth gear shifting, stable acceleration, and comfortable driving in both city traffic and on the highway.

As an item from the Automatic gearboxes category, the transmission is prepared to work with factory vehicle control systems, including modules responsible for managing gear shifts, drivetrain protection, and driving modes (e.g., eco or dynamic – depending on the specific car configuration).

Benefits of using an automatic gearbox in a Mercedes

Using this gearbox in Mercedes W204, W212, and R171 models allows for maintaining consistency with the manufacturer's original drivetrain concept. In practice, this means:

• maintaining factory gear-shifting characteristics,
• comfortable, predictable drivetrain operation in daily use,
• better cooperation with safety and traction control systems,
• reducing the risk of problems resulting from unsuitable replacements.

For workshops and users, it is also important that the gearbox comes from the OEM segment, which facilitates the selection of accessories, oil, and service procedures in accordance with the manufacturer's documentation.

Application in vehicles with a petrol engine

The transmission is intended for use with engines with fuel type: petrol, which is important for both ECU calibration and gear ratio selection. Proper matching of the gearbox to the engine type affects:

• correct shift points under various loads,
• stable engine RPM during acceleration and constant speed driving,
• effective use of power and torque,
• maintaining fuel consumption at a level close to factory specifications.

Thanks to this, installing this gearbox in a properly selected Mercedes model allows for restoring the vehicle's original driving characteristics after the failure of the previous transmission.

Condition, installation, and service aspects

The offered gearbox is a used component, which allows for significantly reducing repair costs compared to purchasing a new transmission, while maintaining the original design. Before installation, standard service procedures are recommended, such as changing the transmission oil, filter, and checking seals in accordance with the vehicle manufacturer's procedures.

For correct selection and installation, it is worth paying attention to compatibility with the specific engine version and the car's production year. The workshop performing the service should have access to Mercedes technical documentation to properly carry out adaptation and any necessary gearbox control unit initialization procedures.
