Oversized Lubrication Control Valve Kit
Part No. 95740-71K

ZF valve name: SCHM-V

Tooling Required:
  • F-95740-TL71
  • VB-FIX
In ZF6HP21/28/34 (Gen. 2) valve bodies, severe wear of the lubrication control valve bore results in loss of converter pressure, cooler flow and critical lube feed resulting in overheating as well as bushing, bearing and planet failures. The Sonnax oversized lubrication control valve kit 95740-71K restores the function of the lube control valve and limits oil loss due to a worn bore.
  • Kit fits either M-shift or E-shift valve bodies
  • Valve is hardcoat anodized to reduce wear
  • Increased valve spool length for additional support at critical sealing area
  • O-ringed end plug improves sealing

Kit is NOT compatible with ZF6HP19/26/32 (Gen.1) units. To differentiate between Gen. 1 and Gen. 2 valve bodies, see ZF Identification Guide.

  • Valve
  • End Plug
  • O-Rings (2) 1 Extra
