CLEANING
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 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 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 MopartATF +4,
Automatic Transmission Fluid, during overhaul and
assembly. Use petroleum jelly, MopartDoor 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.Clean the case in a solvent tank. Flush the case
bores and fluid passages thoroughly with solvent.
Dry the case and all fluid passages with compressed
air. Be sure all solvent is removed from the case and
that all fluid passages are clear.
NOTE: Do not use shop towels or rags to dry the
case (or any other transmission component) unless
they are made from lint-free materials. Lint will stick
to case surfaces and transmission components and
circulate throughout the transmission after assem-
bly. A sufficient quantity of lint can block fluid pas-
sages and interfere with valve body operation.
INSPECTION
Inspect the case for cracks, porous spots, worn
bores, or damaged threads. Damaged threads can be
repaired with Helicoil thread inserts. However, the
case will have to be replaced if it exhibits any type of
damage or wear.
ASSEMBLY
(1) Clean and inspect all components. Replace any
components which show evidence of excessive wear
or scoring.
(2) Install the cooler filter bypass valve.
(3) Torque the bypass valve to specification. The
valve uses a tapered pipe thread and excessive
torque can damage the transmission case. Tighten
the cooler filter bypass valve to 4.5 N´m (40 in.lbs.).
(4) Install a new selector shaft seal using Seal
