Inspection
Check the sprag shaft for scores and for free move-
ment in the housing and sprag.
Check the sprag and control rod springs for loss of
tension or distortion. Check the square lug on the
sprag for broken edges. Check the lugs on the gover-
nor support (park gear) for broken edges. Replace
any park lock components that are worn or damaged.
Check the knob on the end of the control rod for
nicks, burrs and free turning. Replace the rod if the
knob is grooved, or worn, or if the rod is bent. The
park lock rods used in Chrysler 3-speed transmis-
sions are different lengths. If the rod must be re-
placed, be sure to install the correct length and
shape rod.

PARK/NEUTRAL POSITION SWITCH SERVICE
The starter feed circuit of the switch is through the
switch center terminal (Fig. 23). It provides a ground
for the starter solenoid circuit through the gearshift
lever in park and neutral only.
The two outer terminals of the park/neutral posi-
tion switch are for the backup lamp switch circuit.
SWITCH TEST PROCEDURE
(1) Remove wiring connector from switch.
(2) Test continuity between switch center terminal
and transmission case. Continuity should exist onlywhen transmission is in Park or Neutral. Replace
switch if continuity occurs in any gear other than
Park or Neutral.
(3) Shift into reverse and test continuity between
two outside terminals on switch. Continuity should
exist only when transmission is in reverse.
(4) Leave transmission in reverse and test continu-
ity between each switch outer terminal and transmis-
sion case. Continuity should not exist between either
pin and case in reverse.
(5) If switch tests OK, check gearshift linkage ad-
justment or backup light circuit. Replace switch if it
fails continuity tests.
SWITCH REPLACEMENT
(1) Position drain pan under neutral switch.
(2) Disconnect switch wires.
(3) Remove switch from transmission.

switch to 33 Nzm (24 ft. lbs.) torque.
(6) Adjust transmission fluid level as required.
(7) Verify switch operation.
SPEEDOMETER SERVICE
Rear axle gear ratio and tire size determine speed-
ometer pinion requirements. If the pinion must be re-
placed, refer to the parts catalogue information for
the correct part. It is important for speedometer ac-
curacy that the pinion have the correct number of
teeth.
The speedometer assembly used in XJ models is
the new unit type (one-piece) speed sensor (Fig. 24).

CONVERTERÐPUMP SEALÐDRIVE PLATE
SERVICE
Drive Plate
The drive plate can be replaced or removed for ser-
vice access after the transmission is out of the vehi-
cle (Fig. 4).CAUTION: On YJ models with a 2.5L engine and
30RH transmission, special bolts are used to attach
the driveplate to the crankshaft. These bolts have a
smaller hex head for torque converter clearance.
DO NOT interchange these bolts with similar size
bolts for any reason.
Torque Converter
The torque converter and driveplate are accessible
for service after the transmission has been removed
(Fig. 4).
The torque converter is not a serviceable part. If
the converter is contaminated or damaged in any
way, it must be replaced as an assembly.Do not at-
tempt to flush a converter contaminated by
metal or clutch facing particles. Flushing will
not remove these contaminants.
The driveplate is also not serviceable. The drive-
plate should be replaced if damaged in any way.
On converters or driveplates with a starter ring
gear, the ring gear is not replaceable. It will be nec-
essary to replace the converter, or driveplate as an
assembly if the gear teeth are damaged.
Oil Pump Seal Service
The oil pump seal is accessible and can be replaced
after the transmission and torque converter are re-
moved.
Use Special Tool C-3981-B to remove the seal (Fig.
5). To use the tool, first start the tool into the seal by
hand. Next, thread the tool into the seal as far as it
will go. Use a wrench on the tool hex to turn the tool.
Continue tightening until all the tool threads firmly

grip the metal part of the seal. Then tighten the tool
puller screw to withdraw the seal from the pump
body.
Use Special Tool C-4193-A to install the seal (Fig.
6). Be sure to lubricate the pump seal and converter
hub with transmission fluid before installation.
TRANSMISSION AND CONVERTER INSTALLATION
CAUTION: If the transmission was repaired to cor-
rect a problem that generated sludge and debris,
the fluid cooler and lines must be reverse flushed
and the torque converter and drainback valve re-
placed. Sludge and metal or friction particles must
be removed from the cooler system before reinstall-
ing the transmission. This avoids re-contaminating
the repaired transmission. Failure to flush the sys-
tem will result in repeat failure and a shop come-
back.
(1) Lubricate converter drive hub and pump seal
with Mopar ATF Plus transmission fluid. Then in-
stall converter. Turn converter back and forth toalign drive slots in converter hub with pump gear
lugs. Be sure converter is fully seated in pump (Fig.
7).
(2) Temporarily secure converter with C-clamp or
metal strap attached across converter housing.
(3) Position transmission on jack and secure it
with safety chains.

if damaged. Inspect the park gear for chipped or
worn gear teeth or damaged ring grooves. Replace
the gear, if damaged.
Check the teeth on the park gear for wear or dam-
age. Replace the gear if necessary. Inspect the metal
seal rings on the park gear hub. Replace the rings
only if severely worn, or broken.
Minor scratches, or burrs on governor components
can be cleaned up with oil-soaked crocus cloth. How-
ever, do not attempt to salvage components that are
severely worn or scored.
The governor valve is made of aluminum and
the output shaft has been spotfaced to accept
the valve. The aluminum valve must not be
used in prior transmissions. The valve can only
be used with an output shaft that has been
spotfaced for valve end clearance. In addition,
the governor body and output shaft must be
properly indexed during reassembly. Be sure to
index these components as described in the
Transmission Assembly and Adjustment proce-
dures.
Check condition of the park gear seal rings, ring
grooves and gear teeth (Fig. 45). Replace the gear as
an assembly if the teeth or ring grooves are worn, or
damaged.
Replace the park gear front and rear seal rings if
cracked, or worn. The front ring is a plain type andthe rear ring is a hook style. If replacement rings are
both hook-style, be sure the ring ends are properly
hooked together.
GOVERNOR/PARK GEAR ASSEMBLY
(1) Lubricate governor components with Mopar
ATF Plus transmission fluid during assembly.
(2) Install new seal rings on park gear hub (Fig.
45). Install ring with interlock ends first and ring
with plain ends last. Slip each ring on hub and seat
them in grooves. Verify that rear ring ends are se-
curely interlocked before proceeding.
CAUTION: Exercise care when installing the rings.
They are easily broken if overspread or twisted dur-
ing installation.
(3) Insert filter screen in park gear. Note that gear
has one filter bore that is concentric and one that
has a notch in it. Filter goes in bore that is concen-
tric as shown (Fig. 39).
(4) Position governor body on park gear. Be sure
filter is properly aligned in body recess.
(5) Install governor-to-park gear bolts snug but not
to required torque at this time.
