The Wix 58920 transmission filter kit is built for automatic transmissions that need clean fluid flow and reliable filtration. It is a direct-fit service kit for select Ford, Lincoln, and Mercury applications, including classic Ford F-100, F-250, F-350, Mustang, and Thunderbird models.

• Automatic transmission filter kit for light-duty service applications
• Application-specific filtration media helps keep unfiltered fluid from bypassing the filter
• Lock-seamed, sealed construction supports consistent fluid control
• Includes sealing gaskets designed for modern transmission fluids
• Closed top design with automatic transmission filter style
• Cross-reference: FRAM FT1025 and Purolator P225 for the same application

Built for Transmission Service

Wix 58920 is engineered around the needs of automatic transmission maintenance, where clean fluid and proper sealing are critical. The filter construction is designed to keep fluid moving through the filtration media rather than around it, while the included gaskets are matched to the demands of today’s transmission fluids. This makes it a practical choice for servicing older Ford and Mercury drivetrains, including Fits 1964-1966 Ford F-100, Fits 1967-1973 Ford Mustang, and Fits 1959-1974 Lincoln Continental applications.

What It Helps Address

• Transmission fluid contamination from normal wear
• Restricted fluid flow caused by a clogged filter
• Poor sealing at the transmission pan or filter interface
• Service issues during routine automatic transmission maintenance
• Fitment needs for classic Ford, Lincoln, and Mercury automatic transmissions

Installation Notes and Tips

Verify the transmission code and application before installation, especially on vehicles with notes such as Trans Mfr Code: C6 or CB. Inspect the pan, sealing surfaces, and fluid condition during service, and replace worn gaskets as part of the filter change. Confirm the filter style and dimensions against the original unit before assembly.

Quality Assurance

Wix designs its transmission filters with sealed construction and application-specific sealing components to support complete filtration. The 58920 part number is used across a wide range of OE and aftermarket cross-references, including Ford and Motorcraft applications, which helps confirm broad service coverage for the listed vehicles.
