Anatomy of a Transmission: Oil Flow in the Pump-PR-Converter-Cooler Lube Circuits
There are some small diameter and length differences that can cause fit and pressure issues if mismatched into the wrong application. It is recommended to measure the locations shown here to verify that the correct OE or replacement part is fit into the appropriate application during rebuild.

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