Listing details

The gearboxes are sold with a 90-day warranty! They were tested before removal and are in full working order.

Mercedes R171 W204 W212 Automatic Gearbox is a factory-original automatic transmission from the Mercedes family, designed for R171, W204, and W212 series vehicles. The original design ensures consistency with the factory drivetrain architecture, and using a complete gearbox from the same model line allows for maintaining predictable drivetrain performance parameters. This is a solution for users seeking a technically matched component rather than random replacements.

Technical characteristics of the automatic gearbox

The presented transmission belongs to the Automatic gearboxes category, which means fully automated gear shifting without the need for a clutch pedal. The automatic technology used was developed by the Mercedes drivetrain department for smooth, predictable operation in typical road conditions, while maintaining appropriate gear-shifting refinement.

The automatic design of this gearbox is engineered for compatibility with factory controllers and software of R171, W204, and W212 series vehicles, facilitating integration with existing electrical installations and safety systems. This makes it possible to maintain the correct gear-shifting logic, matched to the characteristics of the engines used in these models.

Purpose and compatibility in Mercedes vehicles

The Automatic gearbox from this offer is dedicated for use in Mercedes vehicles of the R171, W204, and W212 series, which were factory-equipped with an automatic transmission. Relying on an original solution from the same model family helps reduce the risk of issues with mechanical fitment, mounting positioning, or drivetrain compatibility.

In practice, this means that with proper compatibility verification by the workshop (especially regarding the engine version and the control system used), the gearbox can be integrated into the existing drivetrain without the need for structural vehicle modifications. This is important from the perspective of durability and maintaining factory performance parameters.

Benefits of choosing an original used automatic gearbox

Choosing an original, used automatic transmission from the same model line is often a more predictable solution than using random replacements or uncertain modifications. The factory design ensures compliance with the manufacturer's project, and thus better integration with the vehicle's electronics, safety systems, and the gearbox cooling system.

Compared to remanufacturing, using a complete, original gearbox avoids situations where individual components come from different sources or have been replaced with parts of inconsistent quality. For workshops specializing in the Mercedes brand, this means more predictable installation time and a lower risk of needing to re-intervene in the drivetrain after a short period of operation.

To better understand the differences between remanufacturing and installing original transmissions, it is worth reading the cost analysis and typical symptoms of damage described in our blog post: Failures of manual gearboxes and the advantages of original used transmissions over remanufacturing. Although the article concerns manual gearboxes, it addresses universal issues of cost-effectiveness and the selection of drivetrain components.

Preparation for installation and workshop recommendations

Due to the fact that this is an item from the Automatic gearboxes category, a standard workshop procedure is recommended before installation: verification of compatibility with the specific vehicle version, inspection of mounting points, preparation of appropriate equipment, and the use of the correct transmission oil in accordance with the vehicle manufacturer's guidelines. Such an approach minimizes the risk of operational problems after installation.

The used condition of the product means that before installation, it is worth conducting a detailed visual and functional assessment at a specialized service center that has experience with Mercedes automatic transmissions. This allows for the early detection of any irregularities and the planning of additional service activities if required.

Expanding the scope of work within the drivetrain
