CLEANING AND INSPECTION

TRANSMISSION COMPONENTS

Clean the gears, shafts, shift components and
transmission housings with a standard parts clean-
ing solvent. Do not use acid or corrosive base sol-
vents. Dry all parts except bearings with compressed
air.
Clean the shaft bearings with a mild solvent such
as Mopar degreasing solvent, Gunk, or similar sol-
vents. Do not dry the bearings with compressed air.
Allow the bearings to either air dry, or wipe them dry
with clean shop towels.
SHIFT LEVER ASSEMBLY
The shift lever assembly is not serviceable. Replace
the lever and shift tower as an assembly if the tower,
lever, lever ball, or internal components are worn, or
damaged.
SHIFT SHAFT AND FORKS
Inspect the shift fork interlock arms and synchro
sleeve contact surfaces (Fig. 134). Replace any fork
exhibiting wear or damage in these areas. Do not
attempt to salvage shift forks.
Check condition of the shift shaft detent plunger
and spring. The plunger should be smooth and free of
nicks, or scores. The plunger spring should be
straight and not collapsed, or distorted. Minor
scratches, or nicks on the plunger can be smoothed
with 320/400 grit emery soaked in oil. Replace the
plunger and spring if in doubt about condition. Check
condition of detent plunger bushings. Replace if dam-
aged.
Inspect the shift shaft, shift shaft bushing and
bearing, the shaft lever, and the lever bushing that
fits over the lever. Replace the shaft if bent, cracked,
or severely scored. Minor burrs, nicks, or scratches
can be smoothed off with 320/400 grit emery cloth
followed by polishing with crocus cloth. Replace the
shift shaft bushing or bearing if damaged.
Replace the shaft lever and bushing if either part
is deformed, or worn. Do not attempt to salvage these
parts as shift fork binding will occur. Replace the roll
pin that secures the lever to the shaft.
FRONT/REAR HOUSINGS AND BEARING
RETAINERS
Inspect the housings carefully. Look for cracks,
stripped threads, scored mating surfaces, damaged
bearing bores, or worn dowel pin holes. Minor nicks
on mating surfaces can be dressed off with a fine file,
or emery cloth. Damaged threads can be renewed by
either re-tapping or installing Helicoil inserts.
