Purpose and technical characteristics

The presented transmission belongs to the group of Automatic Gearboxes used in Mercedes vehicles with 4Matic drive. It has been designed to work with diesel power units, which means it is adapted to the high torque and specific operating characteristics of diesel engines. The transmission design accounts for the requirements of the all-wheel-drive system, ensuring proper power distribution and stable vehicle behavior in various road conditions.

Compatibility and OEM identification

The automatic gearbox is marked with a dedicated OEM part number, which facilitates clear identification and selection for a specific vehicle configuration. Additionally, interchangeable numbers are available, allowing for the verification of compatibility with other versions of the same transmission used in different model variants. When selecting, it is recommended to use OEM markings and vehicle data (VIN) to ensure full mechanical and electronic compatibility with the existing installation.

Performance parameters and installation advantages

The automatic transmission has been designed for comfortable, smooth driving and to reduce jerking during gear changes, which is particularly important in heavier premium SUV models. The use of an automatic system allows for optimal utilization of the diesel engine's characteristics, improving the refinement of the powertrain and reducing driver fatigue in city traffic and on long journeys.

The version designed for 4Matic drive works with the all-wheel-drive system, which translates into stable vehicle handling on surfaces with variable grip. For workshops and service centers, the ability to install it in place of the factory gearbox, while maintaining original mounting points and connection interfaces, is significant, as it shortens work time and reduces the risk of additional modifications.

Condition, origin, and practical application

The offered gearbox is a used item, which allows for a significant reduction in repair costs compared to purchasing a new component, while maintaining the factory design and operating characteristics. This solution is particularly beneficial for vehicles used intensively, where a reasonable balance between financial expenditure and maintaining the original technical specification is important.

In practice, the installation of such a transmission is often chosen in the event of major failures of the existing gearbox, problems with the hydraulic system, or excessive wear of internal components. Using a complete, used unit allows for restoring the efficiency of the powertrain in less time than in the case of a full overhaul, while simultaneously maintaining consistency with the factory Mercedes design.

Support with selection and powertrain expansion

If you are planning a comprehensive repair or upgrade of the powertrain area in your Mercedes and need other elements from the same group, such as a torque converter, control elements, or additional transmission components, check the available parts in the Mercedes Automatic Gearboxes category.
