Valve Body: Assembly

Clean and inspect all valve body components for damage or wear.

CAUTION: Do not force valves or plugs into place during reassembly. If the valve body bores, valves, and plugs are free of distortion or burrs, the valve body components should all slide into place easily. In addition, do not overtighten the transfer plate and valve body screws during reassembly. Overtightening can distort the valve body resulting in valve sticking, cross leakage and unsatisfactory operation. Tighten valve body screws to recommended torque only.
  1. Lubricate valve body bores, valves and plugs with Mopar® ATF Plus 4, Type 9602, transmission fluid.
