Wear is commonly found at different areas in ZF6HP19/26/32 (Gen. 1) and Ford 6R60/6R80 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. The Sonnax oversized pressure regulator valve kit 95740-01K restores valve-to-bore or sleeve clearances so the pressure regulator valve can maintain correct pressures.
Kit is NOT compatible with ZF6HP19/26/32 (Gen.1) units with an 053 separator plate code or ZF6HP21/28/34 (Gen.2) units. To differentiate between Gen. 1 and Gen. 2 valve bodies, see ZF Identification Guide.
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.

A vacuum test at the inner port fails to hold 18 in-hg of vacuum or higher, or if visual wear is detected at the inboard valve bores. If the inner port holds vacuum, but the outer port fails to hold 16 in-hg, use either this oversized pressure regulator valve kit 95740-01K or direct replacement pressure regulator sleeve [95740-03].
