OVERHAUL SERVICE INFORMATION
Inspect the transmission bushings during overhaul.
Bushing condition is important as worn, scored bush­
ings contribute to low pressures, clutch slip and ac­
celerated wear of other components. However, do not
replace bushings as a matter of course. Replace bush­
ings only when they are actually worn, or scored.
Use recommended tools to replace bushings. The
tools are sized and designed to remove, install, and

seat bushings correctly. The bushing replacement
tools are included in Bushing Tool Set C-3887-B.
Pre-sized service bushings are available for replace­
ment purposes. Only the sun gear bushings are not
serviced. Replace the gear and bushings as an assem­
bly.
Heli-Coil inserts can be used to repair damaged,
stripped or worn threads in aluminum parts. These
inserts are available from most automotive jobbers.
Stainless steel inserts are recommended.
The use of crocus cloth is permissible where neces­
sary, providing it is used carefully. When used on
shafts, or valves, use extreme care to avoid rounding
off sharp edges. Sharp edges are vital as they pre­
vent foreign matter from getting between the valve
and valve bore.
Do not reuse oil seals, gaskets, seal rings, or
O-rings during overhaul. Replace these parts as a
matter of course. Also do not reuse snap rings or E-
clips that are bent or distorted. Replace these parts
as well.
Lubricate transmission parts with Mopar ATF
Plus, Type 7176, transmission fluid during overhaul
and assembly. Use petroleum jelly, Mopar Door Ease,
or Ru-Glyde to prelubricate seals, O-rings, and thrust
washers. Petroleum jelly can also be used to hold
parts in place during reassembly.

bores and fluid passages thoroughly with solvent.
