Why This Filter Matters

Transmission fluid carries wear debris over time, and a clogged filter can restrict flow and allow contamination to circulate through the transmission. Replacing the filter at service intervals helps keep fluid moving through the system and reduces the chance of debris-related issues in the valve body and other vital parts. ATP Parts B-431 is a practical choice for owners servicing a Mazda 6 or Mazda CX-5 with the FW6A transmission.

ATP Parts Premium Replacement products are positioned as OE-style service parts for maintenance work where correct fit and dependable filtration are important. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common Problems This Part May Address

• Restricted transmission fluid flow from a dirty filter
