SHIFT
COVER SERVICE
The only serviceable shift cover components are:
• fifth-reverse shift fork pads
• reverse inhibitor
• vent components • backup light switch
• expansion plugs
• shift lever components The shift cover, shift forks, shift rails and detent
components are not serviced individually. The cover
must be replaced as an assembly if the cover, or any shift components are worn or damaged.
Shift
Cover
Inspection
Inspect the cover and shift components whenever
the cover is removed from the gear case. Or, when ever diagnosis indicates inspection is necessary.
Check the forks for wear, distortion, cracks, or be
ing loose on the shift rails. Also check fit of the shift rails in the cover. Replace the cover assembly if the
rails are loose in the cover bores.
Inspect and replace the pads on the fifth-reverse
shift fork if worn. The reverse inhibitor should also
be replaced if worn, or faulty. The expansion plugs at
the rear of the cover can be replaced if loose or leak ing.
A gasket is not used between the shift cover
and gear case. Use Mopar Gasket Maker, or Loc
tite 518 to seal the cover.
Procedures for the serviceable components in the
shift cover as follows:
Fifth-Reverse
Shift
Fork Pad Replacement The plastic shift fork pads are held in place by a
combination of tension and a small locating tang.
Three pads are used on the fork (Fig. 164).
The pads can be removed either by hand or with a
narrow blade screwdriver. To remove the pads by
hand, grasp each pad and tilt it out and off the fork.
If the pads prove difficult to remove by hand, insert a screwdriver blade between the pad and fork and pry
the pad off.
Fig.
164 Shift
Fork
Pad
Locations
Reverse
Inhibitor Replacement The reverse inhibitor mechanism should be
checked for wear or damage whenever diagnosis in
dicates this is necessary.
The inhibitor mechanism is attached to the cover
with two screws (Fig. 165). Attaching screw torque is 8-14 N-m (75-115 in. lbs.).
Vent
Component
Replacement The shift cover vent assembly consists of the vent
tube,
connecting hose, hose clamps, and vent valve (Fig. 166).
If the vent tube is removed for replacement or ser
vice access, apply Mopar silicone adhesive/sealer to
the tube to help secure it in the cover.

TORQUE CONVERTER
AND
DRIVE PLATE SERVICE
After the transmission has been removed, the drive
plate and torque converter can be replaced or re
moved for service access.
The torque converter is not a serviceable part. If
the converter is contaminated by a transmission mal
function, or damaged in any way, it must be replaced as an assembly. Do not attempt to flush a con
verter contaminated by metal or clutch facing
particles. Flushing will not remove these con
taminants.
A new torque converter and oil pump are used
in 1993, 42RH transmissions. The new converter
has a different style drive hub. The hub was changed to accept the new design drive flats on
the oil pump inner gear. The drive flats replace
the square lugs used previously. If converter re placement should become necessary, be sure to
use the new style converter. The new converter and oil pump are not interchangeable with pre
vious style parts.

CAUTION:
The

gear
on

torque
converters
can be
replaced when necessary. How
ever,
the
ring gear
on
torque converters with
a
modulated converter clutch, cannot
be
replaced.
The heat from

if the

RING GEAR REMOWAL
(1) Cut through weld material at rear side of ring
gear with a hack saw or grinding wheel. Be careful
to avoid cutting or grinding into front cover. (2) Scribe heavy line on front cover next to front
face of ring gear. Line is needed to properly locate new gear on converter. (3) Support torque converter on front cover with
blocks of wood (Fig. 6) Position blocks adjacent to converter lugs to avoid altering lug position. The
torque converter must not rest on the front cover hub during this operation.

beforehand.
(1) Check torque converter hub and hub drive
notches for sharp edges burrs, scratches, or nicks.
Polish hub and notches with 400 grit paper or crocus
cloth if necessary. Hub must be smooth to avoid dam aging pump seal during installation.
(2) Lubricate converter hub and pump seal lip with
transmission fluid.
(3) Position converter hub so drive slots will be
aligned with pump gears. Then carefully insert con
verter hub into pump and gears.
(4) Verify that converter is fully seated. Use
