ATP Parts B-518 Transmission Filter Kit

Transmission Filter Kit for Mercedes-Benz

ATP Parts B-518 is a transmission filter kit for Mercedes-Benz applications that use the listed transmissions and model years. It is built to help keep transmission fluid clean so internal valve body and hydraulic components stay free of debris.

• Fits a wide range of Mercedes-Benz passenger cars and SUVs from 2015-2020.
• Helps remove wear particles that can circulate through the transmission.
• Supports cleaner fluid flow through the valve body and other critical components.
• Direct service part for routine transmission maintenance.

How It Works

Transmission filter service is an important part of maintaining smooth transmission operation. Over time, normal wear creates debris that can collect in the filter and restrict fluid flow. Replacing the filter with ATP Parts B-518 helps maintain cleaner transmission fluid and reduces the chance of clogging that can affect internal operation. This part is used across many Mercedes-Benz models, including GLC300, E300, and S560 applications, and it is identified by part number B-518.

Common Problems It Helps Address

• Restricted transmission fluid flow caused by debris buildup.
• Contamination that can affect valve body operation.
• Maintenance intervals where the filter should be renewed.
• Wear-related debris circulating through the transmission system.

Installation Notes

Verify the transmission code and vehicle application before ordering, especially for the 2017 CLS400 note that specifies 725.011 and 725.041. Match the filter kit to the exact Mercedes-Benz model and year listed in the fitment data. Professional installation is recommended for transmission service.

Quality Assurance

ATP Parts positions this filter as a service component for keeping transmission fluid clean and helping extend transmission life. Part number B-518 is listed for multiple Mercedes-Benz applications, and the fitment data should be checked carefully before installation.
