OE Replacement Transmission Filter Kit

ATP Parts TF-39 is an OE Replacement transmission filter kit for service on a wide range of Ford, Mercury, and Lincoln applications. It is built to help keep transmission fluid cleaner so internal passages, the valve body, and other critical components stay free of debris from normal wear.

For drivers maintaining a Ford Bronco, Mustang, F-100, or Mercury Cougar, regular filter service is a practical step toward preserving transmission performance and reducing avoidable repair costs. ATP Parts TF-39 follows the OE-style service approach for these older automatic transmission applications.

Detailed Description

ATP Parts OE Replacement line focuses on direct-fit service components for maintenance work, and TF-39 is a transmission filter kit intended for older automatic transmissions that rely on clean fluid to operate correctly. By replacing a clogged or worn filter during routine service, you help maintain fluid cleanliness and reduce the chance of restricted flow that can affect shifting and drivability. This part number TF-39 is listed for applications including Ford Bronco, Ford Mustang, Ford F-100, Mercury Cougar, and related models across the 1964-1982 range.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Address

• Dirty or contaminated transmission fluid
• Debris buildup that can restrict internal passages
• Valve body clogging from normal wear particles
• Service intervals where the existing filter is no longer effective
• Transmission maintenance on classic Ford and Mercury vehicles

Installation Notes and Tips

Verify the transmission type and pan configuration before ordering, especially on 1977-1980 Mercury Monarch and 1979 Ford Mustang applications noted with an open slot, and the 1974 Mercury Cougar listing marked for C4 only. Confirm the vehicle year, make, and model against the fitment list for TF-39 before installation. Clean the pan and inspect the transmission fluid condition during service.
