• No bypass by design: WIX designs and builds these filters so no unfiltered fluid can get around the application-specific filtration media.
• Lock-seamed, sealed assembly: The filter assembly is lock-seamed and sealed, and WIX pairs it with application-specific sealing components designed to provide complete filtration.
• Sealing gaskets included: The kit comes with sealing gaskets that WIX specifically designed for use with today's sophisticated transmission fluids.

The filter's job is to trap contaminants in the transmission fluid before that fluid circulates back through the transmission. Over time, trapped debris can restrict flow through the filter. Delayed or erratic shifting, slipping or unusual transmission noise can have many causes. If a restricted filter is one of them, this kit replaces the filter along with its sealing gaskets. Diagnose the transmission before replacing parts, and follow the service interval and procedure in your vehicle's service information.
