Purpose and technical function

The gearbox oil sump pan in Mercedes C-Class, E-Class, and S-Class models of the W204, W205, W212, and W222 generations operates in a demanding environment where maintaining the correct level and circulation of transmission fluid is critical. This component:

• creates a sealed reservoir for the transmission fluid,
• stabilizes lubrication conditions for the transmission and control system,
• supports heat dissipation from the oil,
• ensures proper system operation during load and temperature changes.

Thanks to a design tailored to the specific gearbox in Diesel-powered vehicles, the correct oil flow geometry and compatibility with factory mounting points are maintained.

Compatibility with Mercedes models

The offered oil sump pan is designed for gearboxes installed in popular Mercedes W204, W205, W212, and W222 models with diesel engines. This means that:

• the spacing of the mounting holes is consistent with the factory gearbox housing,
• the shape of the sump is adapted to the chassis and equipment of the specific body style,
• compatibility with original sealing and filtration elements is maintained.

Selecting the correct gearbox oil sump pan for a specific model and powertrain version is crucial to avoid leaks, vibrations, and oil level issues.

Characteristics of the used component

The presented oil sump pan comes from a used vehicle, which allows for an economical repair while maintaining the manufacturer's original specifications. The used component:

• retains factory geometry and mounting points,
• enables installation in place of a damaged or corroded sump,
• allows for reduced service costs while maintaining compliance with Mercedes technical documentation.

Before installation, standard service procedures are recommended: checking the mating surfaces, using a new gasket, and changing the transmission fluid according to the vehicle manufacturer's recommendations.

Benefits of using an original gearbox oil sump pan

Using an original gearbox oil sump pan in a diesel-powered Mercedes translates into a number of practical benefits:

• Full dimensional compatibility – no need for alterations, adjustments, or modifications to mounting elements.
• Stable gearbox operating conditions – correct oil level and distribution, which supports shift quality and transmission durability.
• Hassle-free service – easier diagnosis of potential leaks and predictable behavior of the lubrication system.

For workshops and individual users, this means a lower risk of complaints and a predictable installation time.

Installation and maintenance tips

When replacing the gearbox oil sump pan in Mercedes W204, W205, W212, and W222 models, it is worth paying attention to several technical aspects:

• thorough cleaning of the contact surface between the gearbox and the sump,
• using a new gasket and the correct bolt tightening torque,
• checking the condition of the threads in the gearbox housing,
• refilling and bleeding the oil system according to the service procedure.

Performing the operation in this manner helps restore system tightness and ensures the proper operation of the automatic transmission in a diesel-powered vehicle.
