OVERHAUL SERVICE INFORMATION
Inspect all the transmission bushings during over­
haul. Bushing condition is important as worn, scored
bushings contribute to low pressures, clutch slip and
accelerated wear of other components. Replace worn,
or scored bushings, or if doubt exists about bushing
condition.
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 Sets C-3887-B, or
C-3887-J.
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 are recommended for repairing
damaged, stripped or worn threads in aluminum
parts. These inserts are available from most automo­
tive jobbers. Stainless steel inserts are preferred.
The use of crocus cloth is permissible where neces­
sary, providing it is used carefully. When used on
valves, use extreme care to avoid rounding off sharp
edges. Sharp edges are vital as they prevent 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
