Key Features

• Automatic transmission filter kit for light-duty service

• Includes sealing gaskets designed for modern transmission fluids
• Wix part number 58898

Product Details

Wix 58898 is an automatic transmission filter kit engineered to maintain filtration integrity inside the transmission. The filter construction is designed so fluid passes through the media rather than around it, while the sealing components and gaskets are matched to the demands of today’s transmission fluid formulations. This makes it a practical service part for maintaining clean fluid flow in applications such as the Ford Explorer, Ford Explorer Sport Trac, Mercury Mountaineer, and Lincoln Aviator.

This part cross-references Motorcraft FT140 for the same application.

What It Helps Address

• Restricted transmission fluid flow caused by a clogged filter
• Contamination circulating through the automatic transmission
• Fluid bypass from worn or poorly sealed filter assemblies
• Service issues during transmission maintenance on Ford Explorer and related models
• Leak concerns at the filter sealing surfaces

Installation Notes

• Verify transmission code and model year before ordering, especially on 5R55S applications.
• Replace the filter during transmission service and inspect the pan and sealing surfaces for debris.
• Use the included gaskets with the correct transmission fluid specified for the vehicle.
• Confirm fitment for 2002-2010 Ford Explorer, 2004-2010 Ford Explorer Sport Trac, 2002-2010 Mercury Mountaineer, and 2003-2005 Lincoln Aviator.

Quality Assurance

Wix designs its transmission filters with sealed construction and application-specific sealing components to support complete filtration in modern automatic transmissions. The 58898 is built as a service replacement for the listed OE-style applications.
