body service procedures are detailed in the overhaul
section.
The only serviceable valve body components are:
²park lock rod and E-clip
²switch valve and spring
²pressure adjusting screw bracket
²throttle valve lever
²manual lever
²manual lever shaft seal, washer, E-clip and detent
ball
²fluid filter
²converter clutch solenoid
The remaining valve body components are serviced
only as part of a complete valve body assembly.

Governor/Park Gear Cleaning and Inspection
Thoroughly clean all the governor parts in a suit-
able cleaning solution but do not use any type of
caustic cleaning agents.
The governor weight components (Fig. 20) and the
governor valve (Fig. 21), must slide freely in their
bores when clean and dry. Minor surface scratches
and burrs can be smoothed with crocus cloth
The aluminum governor valve and outer weight
have a hard coating on them. Check condition of this
coating carefully. Do not reuse either part if the coat-
ing is damaged.
Inspect the governor weight spring for distortion.
Replace the spring, if distorted, collapsed, or broken.
Clean the filter in solvent and dry it with low pres-
sure compressed air. Replace the filter, if damaged.
Inspect the park gear for chipped or worn gear teeth
or damaged ring grooves. Replace the gear, if dam-
aged.
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.
GOVERNOR/PARK GEAR ASSEMBLY AND
INSTALLATION
(1) Lubricate governor components with transmis-
sion fluid during assembly.(2) Install new seal rings on park gear hub. 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 securely inter-
locked 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. 16).
(4) Position governor body on park gear. Be sure
filter is properly aligned in body recess.
(5) Install governor body bolts. Do not fully tighten
bolts at this time.
(6) Assemble governor weight components (Fig.
20). Then install weight assembly in governor body.
Be sure inner weight snap ring is fully seated
before proceeding.
(7) Install retainer washer and snap ring that se-
cure governor weight assembly in governor body.
(8) Align and install park gear/governor assembly
on output shaft.Be sure hole in output shaft for
governor valve shaft is aligned with governor
valve bore in governor body. Valve shaft will

(11) Install an E-clip on one end of governor valve
shaft. Be sure rounded side of E-clip is facing out
(away from weight).
(12) Insert governor valve shaft through governor
weight. Be sure shaft slides freely in bore.
(13) Install governor valve on shaft and in gover-
nor body bore.
(14) Install remaining E-clip on governor valve
shaft. Be sure rounded side of E-clip is facing out
(away from valve).
(15) Install governor body-park gear snap rings
and washer on output shaft as follows:
(a) On models with single snap ring, install snap
ring. Be sure ring is seated in shaft.
(b) On models with thrust washer and two snap
rings, install thin snap ring first. Then install
thrust washer second, and thick snap ring last
(Fig. 14).
16(c) Verify correct position of snap rings.Be
sure flat side of each snap ring is toward gov-
ernor body.(16) Tighten governor body-to-park gear bolts to 11
Nzm (95 in. lbs.).
(17) Install extension housing/adapter and gasket
on transmission. Tighten housing/adapter bolts to 32
Nzm (24 ft. lbs.).

PARK LOCK COMPONENT REPLACEMENT
COMPONENT REMOVAL
(1) Raise vehicle and remove transfer case and
adapter housing from transmission.
(2) Slide sprag shaft out of adapter housing and re-
move park sprag and spring (Fig. 22).

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.
COMPONENT INSTALLATION
(1) Install park lock rod on valve body.
(2) Install reaction plug and pin assembly in the
housing and install the snap ring.
(3) Position sprag and spring in housing and in-
stall sprag shaft. Be sure square lug on sprag is fac-
ing park gear and that spring is positioned so it
moves sprag away from park gear.
(4) Install valve body.
(5) Install adapter housing and transfer case.
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.
(4) Move shift lever to Park and Neutral positions.
Inspect manual lever fingers, lever and shaft for
proper alignment with switch opening in case. Re-
place lever if worn or bent. Do not attempt to
straighten the lever.
(5) Install new switch and seal in case. Tighten
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).
However, YJ models may be equipped with either the
new unit style, or the older style that has a two-piece

remove clamp (Fig. 26).
(6) Remove speedometer adapter, sensor adapter
and speedometer pinion as assembly.
