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.

The bore on one side of the gear inside diameter
(I.D.) is chamfered. Be sure the chamfered side

CAUTION: The pump inner gear is a one way fit.
The bore on one side of the gear inside diameter
(I.D.) is chamfered. Be sure the chamfered side
faces forward (to front of pump).
(6) Install new thrust washer on hub of reaction
shaft support. Lubricate washer with transmission
fluid or petroleum jelly.
(7) If reaction shaft seal rings are being replaced,
install new seal rings on support hub (Fig. 59). Lu-
bricate seal rings with transmission fluid or petro-
leum jelly after installation. Squeeze each ring until
ring ends are securely hooked together.
CAUTION: The reaction shaft support seal rings will
break if overspread, or twisted. If new rings are be-
ing installed, spread them only enough for installa-
tion. Also be very sure the ring ends are securely
hooked together after installation. Otherwise, the
rings will either prevent pump installation, or break
during installation.
(8) Install reaction shaft support on pump housing
(Fig. 60).(9) Align reaction support on pump housing. Use
alignment marks made at disassembly. Or, rotate
support until bolt holes in support and pump housing
are all aligned (holes are offset for one-way fit).
(10) Install all bolts that attach support to pump
housing. Then tighten bolts finger tight.
(11) Tighten support-to-pump bolts to required
torque as follows:
(a) Reverse pump assembly and install it in
transmission case. Position pump so bolts are fac-
ing out and are accessible.
(b) Secure pump assembly in case with 2 or 3
bolts, or with pilot studs.
(c) Tighten support-to-pump bolts to 20 Nzm (15
ft. lbs.).
(d) Remove pump assembly from transmission
case.
(12) Install new oil seal in pump with Special Tool
C-4193 and Tool Handle C-4171 (Fig. 61). Be sure
seal lip faces inward.
