Product Details
Description
Fits 6R80 '09-'14. Cannot be used in units that have a 053 separator plate.
OE valve name: SYS.DR-V
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.
- Hardcoat anodized aluminum valve combats premature wear
- Alloy aluminum sleeve is significantly more wear-resistant than the OE sleeve
- Salvages valve body castings
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.
- Valve
- Sleeve
- Reamer F-Tool Kit - Part No. F-95740-TL
Symptoms:
- Poor shift quality
- Flare shifts
- Harsh shifts
- Erratic line pressure
- Slips in Forward & Reverse
- Delayed Reverse
- No Reverse
- TCC slip
Cause:
Excessive valve and bore clearance allows critical line pressure to exhaust causing high or low pressure depending on the location of the wear.Correction:
Sonnax oversized pressure regulator valve kit restores the correct valve/bore clearances and line pressure control as well as prevent future wear in this area.Warning:
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.
