Product Description
Fits: ZF6HP19, ZF6HP26, ZF6HP32, ZF6HP21, ZF6HP28, ZF6HP34
Kit is compatible with all ZF6HP21/28/34 (Gen. 2) units, and only ZF6HP19/26/32 (Gen. 1) units with 053 separator plate.
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. Sonnax O-ringed internal end plug kit 95740-30K services the seven individual bores in the ZF6HP19/26/32 (Gen. 1) with 053 separator plate code, and ZF6HP21/28/34 (Gen. 2) valve bodies which use internal end plugs to isolate valves from solenoids. The double O-ringed end plugs replace damaged OE end plugs and restore pressure containment to the valve bore.
- Prevents loss of critical pressure
- Requires no machining or special tools
- Services all seven bores to isolate valve from solenoids with 12mm internal end plugs
- Drop-in Zip Valve® parts install quickly and easily
Notes
To differentiate between Gen. 1 and Gen. 2 valve bodies, see ZF Identification Guide.
Symptoms
- Inconsistent shift quality
Cause
Valves, springs and pressurized fluid repeatedly push on the end plugs, causing the plugs to deform and wear. As a result, critical pressure is lost due to excessive clearance between the plug and bore.
Correction
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.

- End Plugs (7) 12mm
