Purpose and compatibility

The presented automatic transmission has been designed for use in popular Mercedes C-Class and E-Class models, as well as the R-series roadster, in versions equipped with an automatic transmission. The design is adapted to work with the factory control system, which allows for maintaining proper gear shift strategies, comfort functions, and performance characteristics intended by the manufacturer.

By using an original solution from the Automatic transmissions group, it is possible to maintain correct cooperation with the vehicle's electronics, transmission oil cooling system, and factory mounting points on the body and engine.

Technical characteristics of the automatic transmission

The automatic transmission in this version uses an integrated gear control system, which is responsible for selecting gears depending on load, vehicle speed, and driving mode. The applied design enables:

• smooth gear shifting without jerking,
• efficient torque transmission across the full engine operating range,
• cooperation with driver assistance systems, such as electronic stability control or traction control,
• adjustment of gear shifting characteristics to the factory settings of a given Mercedes model.

This solution is particularly beneficial for users expecting comfortable, predictable drivetrain operation and the preservation of the vehicle's original driving parameters.

Condition, origin, and advantages of using a used transmission

The offered transmission comes from a Mercedes vehicle and is a used component, which allows for significantly reducing repair costs compared to purchasing a brand-new unit or a full overhaul. Choosing such a solution is often optimal in the event of a major failure of the existing transmission, when repair costs exceed the vehicle's value or are economically unjustified.

Key benefits of using a used automatic transmission include:

• lower total cost of drivetrain repair,
• preservation of the original design and transmission operating parameters,
• possibility of faster vehicle restoration thanks to a ready-to-install component.

To better assess the cost-effectiveness of such a solution and learn about the most important issues related to selection and installation, it is worth reading the guide: Used transmission – when is it worth it and what you need to remember.

Selection, identification, and installation aspects

When selecting this transmission, it is crucial to verify compatibility with the specific vehicle model, year, and drivetrain version. Manufacturer markings, OEM part numbers, and interchangeable numbers are helpful in this regard, allowing for precise matching of the transmission to a given car. Proper identification minimizes the risk of installation problems, gear ratio mismatches, or communication errors with the vehicle's electronics.

The installation process itself requires the use of appropriate service procedures, including proper filling and bleeding of the oil system, transmission adaptation in the vehicle's ECU (if required), and checking connection tightness. Using an original automatic transmission facilitates workshop work, as all mounting points, connections, and electrical interfaces are consistent with the factory specification.
