6R80 Transmission Oversize Pressure Regulator Valve Kit Sonnax Number 95740-46K 2015 On.
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 oversize 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
- Poor shift quality
- Flare shifts
- Harsh shifts
- Erratic line pressure
- Slips in Forward & Reverse
- Delayed Reverse
- No Reverse
- TCC slip
Excess valve and bore clearance allows critical line pressure to exhaust causing high or low pressure depending on the location of the wear.
Sonnax oversize valve and tool kits restore the correct valve/bore clearances and line pressure control as well as prevent future wear in this area.
Verify OE valve and sleeve measurements before use.
