damage or foreign material.
6. Reinstall the poppet, spring and plug (with shims and
o-ring) into the housing. Tighten the plug to a torque of
30 to 70 ft-lb.

Start the engine and let it run for one to two minutes,
then turn the engine off and check the oil level again.
Check the transmission for leaks.
