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.ZF6HP19,ZF6HP21,ZF6HP26,ZF6HP28,ZF6HP32,ZF6HP34
O-Ringed Internal End Plug Kit
Part No.95740-30K
Kit is compatible with all ZF6HP21/28/34 (Gen. 2) units, and only ZF6HP19/26/32 (Gen. 1) units that have a 053 separator plate code.

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
To differentiate between Gen. 1 and Gen. 2 valve bodies, seeZF Identification Guide.
- End Plugs (7)12mm
- O-Rings (20)6 Extra

ZF6HP21/28/34 (Gen. 2) Vacuum Test Guide
You need this if...
Vacuum testing at the port(s) indicated fails to hold the recommended minimum in-Hg, or if wear is visually detected.
Note: Port configurations may change due to variations of casting channels between M and E shift, as well as make and model. The location that needs checking will be the port with the retaining clip.
