Verify OE valve and sleeve measurements before use.
Wear is commonly found at different areas in Ford 6R80 pressure regulator bores. Wear at the sleeve end causes high line pressure leading to broken drums, pistons or other parts, as well as restricted converter/lubrication flow. Wear at the spring end of the bore allows low line pressure and lube/TC fluid to exhaust leading to a burned converter clutch and premature bushing failure. Sonnax oversized pressure regulator valve kit 95740-46K restores valve-to-bore or sleeve clearances so the pressure regulator valve can maintain correct pressures.
Sonnax valve body layouts provide a detailed overview of individual units making it quick and easy to determine what’s available for the specific valve body you’re working on. See all Sonnax valve body layouts.
Vacuum testing at the port(s) indicated fails to hold the recommended minimum in-Hg, or if wear is visually detected.
