Valves, springs and pressurized fluid repeatedly push on end plugs causing them to deform and wear. As a result critical pressure is lost due to excessive clearance between the plug and bore. The Sonnax double O-ring sealed end plug kit for ZF6HP19/26/32 (Gen. 1) and Ford 6R60, 6R75, 6R80, 6R100 units replace the damaged OE end plugs and restore pressure containment to the valve bore. Sonnax O-ringed internal end plug kit 95740-25K services the four individual bores in the valve body which use internal end plugs to isolate valves from solenoids.
Kit is NOT compatible with ZF6HP21/28/34 (Gen.2) units. To differentiate between Gen. 1 and Gen. 2 valve bodies, see ZF Identification Guide.

Sonnax drop-in O-ringed end plugs restore correct circuit pressures. The O-ring provides additional sealing to reduce pressure losses past the end plug.| O-Ringed End Plug Location Key | |||
