Application and function in the drivetrain

The oil filler pipe is part of the Automatic gearboxes group and works with the automatic transmission in Mercedes C-Class W203 and SLK R170 models. Its task is to ensure controlled ATF flow during filling and servicing, which contributes to:

• maintaining the correct oil level in the gearbox,
• stable transmission operation during gear changes,
• reducing the risk of overheating and excessive wear of internal components.

Thanks to its dedicated shape and factory connections, the pipe works with the system from the front of the vehicle, maintaining proper routing and connection tightness.

Compatibility and fit for Mercedes C W203 / SLK R170

The offered pipe has been designed for specific Mercedes architectures, which translates into a precise fit for the drivetrain and bodywork. The original geometry of the connections and the appropriate length of the pipe facilitate installation and limit the risk of stress, abrasion, or leaks during operation.

To ensure correct selection, it is worth comparing the type of gearbox used and the location of the component in the vehicle with the currently installed pipe. The product has assigned OEM part numbers and interchangeable numbers, which facilitates compatibility verification in service catalogs and parts selection systems.

Technical characteristics and installation

The automatic gearbox oil filler pipe for Mercedes has been designed to work in demanding thermal and pressure conditions typical of automatic transmission systems. The pipe construction ensures:

• stable routing of the working medium in the front of the vehicle,
• adequate resistance to transmission oil temperature,
• the possibility of repeated disassembly and assembly during service maintenance.

When replacing, it is recommended to follow the vehicle manufacturer's procedures, in particular those concerning system venting, leak checks, and final oil level verification after the gearbox has warmed up.

Condition of the item and benefits of choosing a used part

The offered pipe is a used component, which allows for a significant reduction in repair costs compared to purchasing a new part, while maintaining the original design specifications. In the case of oil filler pipes, maintaining tightness, connection integrity, and the absence of mechanical damage is key – these are the aspects worth verifying before installation.

For drivers considering different transmission repair strategies, a guide describing the cost-effectiveness of purchasing parts from the secondary market will be useful.
