Symptoms:

  • Soft shifts
  • Flare shifts
  • Harsh shifts
  • Burnt clutches
  • Pressure loss

Cause:

Damaged, deformed and/or eroded end plugs and bores allow loss of critical hydraulic pressure.

Correction:

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 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.

  • Prevents loss of critical pressure
  • Services all 6/3 (PBW/PBC) bores where end plug sealing is critical for proper function
  • Minimal end plug-to-bore clearance with added O-ring for positive seal
  • #8-32 Threaded bore in end plug outboard face aids installation and removal
  • Drop-in Zip Valve™ parts install quickly and easily
