Technical specifications and intended use

The presented automatic transmission belongs to the Automatic gearboxes group and has been designed to work with petrol units in high-end Mercedes models. The gearbox construction is adapted to the torque characteristics of petrol engines, which translates into smooth gear shifts, stable acceleration, and predictable vehicle behavior across the full load range.

This type of automatic transmission is particularly valued in applications where driving comfort, precise gear shifting, and seamless integration with the vehicle's factory electronics are essential. Using an original Mercedes solution reduces the risk of compatibility issues with controllers, wiring harnesses, and software.

Benefits of using an original Mercedes automatic gearbox

Choosing an original gearbox from the Automatic gearboxes group for a Mercedes allows you to maintain the factory drivetrain performance parameters. Properly selected gear ratios, shift characteristics, and cooperation with safety systems (such as electronic stability control or traction control) are consistent with the vehicle manufacturer's specifications.

The main advantages of this configuration include:

• maintaining factory acceleration and downshift characteristics,
• consistent operation with the original control software,
• no need for mechanical modifications to the housing or mounts,
• the ability to utilize the existing transmission cooling and lubrication infrastructure.

For workshops, this means shorter installation time and a lower risk of unforeseen modifications, and for the user – predictable vehicle behavior after the repair.

Gearbox selection and installation support

When selecting an automatic gearbox for a Mercedes, it is crucial to verify compatibility with the specific engine version, fuel type, and the installed controller. In practice, this means checking the gearbox markings, vehicle configuration, and catalog data to avoid issues with electronic communication and mechanical connections.
