Key Features

• Cartridge transmission filter style for bypass filter applications
• Cellulose media for fine particle filtration
• 1.00 micron rating for capturing small debris
• Heavy-duty construction for service use
• Corrosion-resistant materials and sealing components for leak resistance
• Built to support OEM transmission filter change intervals
• Part number 57702 for direct catalog lookup

Detailed Description

WIX 57702 transmission filter kit is engineered with premium media selected for the application, along with strong center tube and end-cap construction to maintain filtration performance under operating stress. The filter measures 3.360 inches in height and uses a cartridge transmission filter design with a 0.385-inch inner diameter bottom, 1.811-inch outer diameter bottom, and 1.774-inch outer diameter top. This makes it a practical service part for Ford trucks and vans that require a bypass transmission filter replacement.

This part cross-references Ford 3C3Z7B155BA and Motorcraft FT145 for the same application. If you are servicing a Ford E-350 Super Duty, F-350 Super Duty, or Excursion transmission, the WIX 57702 offers a direct-fit maintenance solution that aligns with OEM service intervals.

What It Helps Address

• Transmission fluid contamination from normal wear
• Restricted fluid flow caused by a loaded filter
• Premature transmission wear from fine debris
• Service issues on bypass-style transmission filter systems
• Maintenance needs on Ford E-Series, F-Series Super Duty, and Excursion models
