OE end plugs are designed to prevent critical pressure loss by capping the bore while also functioning as a spring or valve stop. Repetitive spring motion, valve impact and fluid pressure variations cause wear between the end plug and bore mating surface, allowing vital pressure to escape the circuit.
Sonnax O-ringed end plug kit 85740-01K services Chrysler 948TE, Honda/Acura, 9-speed and ZF9HP48 valve bodies. The two individual bores in PBW (Park By Wire) and one bore in PBC (Park By Cable) that use internal end plugs to isolate valves from solenoids are serviced by double O-ringed internal end plugs, which replace damaged OE plugs and restore pressure containment to the bores. The kit also includes single O-ringed end plugs to service the four 13mm bores in PBW and two 13mm bores in PBC valve bodies.
Services complete PBW (Park by Wire) valve body or PBC (Park by Cable) valve body with one extra internal and one external end plug.
