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.

• Hardcoat anodized aluminum valve combats premature wear
• Alloy aluminum sleeve is significantly more wear-resistant than the OE sleeve
