Detailed Description

Wix 58923 is an automatic transmission filter kit engineered for select Ford and Mercury vehicles from 1965 through 1970. It is designed for transmissions that require a closed-top filter style and light-duty service, with sealing components matched to the application. This kit is a practical choice for owners servicing a Ford Mustang, Ford Bronco, or Ford F-100 transmission system where proper fluid filtration is critical to transmission performance.

Wix transmission filter kits are built to control fluid flow through the filtration media rather than allowing bypass around it. The sealed assembly and application-specific gasket design help maintain a proper seal during transmission service. This part cross-references Purolator P226 and FRAM FT1027 for the same application.

What This Part Helps Address

• Dirty or contaminated automatic transmission fluid
• Poor filtration caused by a worn or clogged filter
• Fluid bypass around the filter media
• Leak concerns related to aged transmission sealing components
• Service needs on older Ford and Mercury automatic transmissions
