GOVERNOR
AND
PARK LOCK SERVICE—42RH/
46RH

The governor and park lock components are located
within the overdrive unit and cannot be serviced in
the vehicle. The overdrive unit must be removed and disassem­
bled for access to the governor and park lock compo­
nents.
Refer to the 42RH/46RH overdrive unit service sec­
tions for repair procedures.

COMPONENT REMOVAL
(1) Remove extension housing as described in this
section. (2) Slide sprag shaft out of extension housing and
remove sprag and spring (Fig. 23).
(3) Remove snap ring and slide reaction plug and
pin assembly out of housing. (4) If park rod requires service, it will be necessary
to remove valve body. Refer to Valve Body Service
procedures in this section.

COMPONENT INSPECTION
Inspect the sprag shaft for scores and free move­
ment in the housing and sprag. Inspect the sprag and control rod springs for distortion and loss of tension.
Inspect the square lug on the sprag for broken

edges.
Check the lugs on the park gear for damage. Inspect the ball on the end of the control rod for
nicks and burrs. Also be sure the ball rotates freely.

VALVE BODY
SERVICE

GENERAL SERVICE
INFORMATION
The valve body can be removed for service without
having to remove the entire transmission assembly. The valve body can be disassembled for cleaning
and inspection of the individual components. Refer to
the procedures in the Transmission Unit Subassem­
bly Overhaul section.
The only serviceable valve body components are

the:

• manual lever
• manual lever washer/seal/E-clip and shaft seal
• manual lever detent ball
• throttle lever
• fluid filter
• overdrive solenoid and connector assembly
• switch valve, spring and adjusting screw bracket • converter clutch solenoid The remaining valve body components are serviced
only as part of a complete valve body assembly.

VALVE
BODY
REMOVAL
(1) Raise vehicle.
(2) Remove oil pan and drain fluid.
(3) Loosen clamp bolts and remove throttle and
manual valve levers from manual lever shaft. (4) Remove park/neutral position switch. (5) Remove filter from valve body.
(6) Disconnect converter clutch solenoid wire from
case connector.

OVERHAUL SERVICE
INFORMATION

Inspect all the transmission bushings during over­
haul. Bushing condition is important as worn, scored
bushings contribute to low pressures, clutch slip and accelerated wear of other components. Do not replace
bushings as a matter of course. Replace bushings
only when actually worn or scored. Use recommended tools to replace bushings. The
tools are sized and designed to remove, install and seat bushings correctly, The bushing replacement
tools are included in Bushing Tool Set C-3887-B. The
tool set is manufactured by the Miller Tool Co. and is available through the dealer tool program. Pre-sized service bushings are available for re­
placement purposes. Only the sun gear bushings are
not serviced. Low cost of the sun gear assembly
makes it easier to simply replace the gear and bush­
ings as an assembly. Heli-Coil inserts are recommended for repairing
damaged, stripped or worn threads in aluminum

parts.
These inserts are available from most automo­
tive jobbers. Stainless steel inserts are preferred. The use of crocus cloth is permissible where neces­
sary, providing it is used carefully. When used on
valves, use extreme care to avoid rounding off sharp
edges.
Sharp edges are vital as they prevent foreign
matter from getting between the valve and valve

bore.

Do not reuse oil seals, gaskets, seal rings, or
O-rings during overhaul. Replace these parts as a
matter of course. Also do not reuse snap rings or
E-clips that are bent or distorted. Replace these parts as well.
Lubricate transmission parts with Mopar ATF

Plus,
Type 7176, or Dexron II™ transmission fluid during overhaul and assembly.
Use Ru-Glyde or Door Eze to lubricate clutch pis­
ton seals. Use petroleum jelly to lubricate O-rings and thrust washers. Petroleum jelly can also be used
to hold parts in place during reassembly.

TRANSMISSION
CASE
CLEAN1N8
AND
INSPECTION

Clean the case in a solvent tank. Flush the case
bores and fluid passages thoroughly with solvent. Dry the case and all fluid passages with compressed
air. Be sure all solvent is removed from the case and
that all fluid passages are clear. Do not use shop towels or rags to dry the case
(or any other transmission component) unless
they are made from lint-free materials. Lint will
readily adhere to case surfaces and transmission
components and will circulate throughout the
transmission after assembly. A sufficient quan­
tity of lint can block fluid passages and interfere
with valve body operation. Inspect the case for cracks, porous spots, worn

bores,
or damaged threads. Damaged threads can be repaired with Helicoil thread inserts. However, the
case will have to be replaced if it exhibits any type of
damage or wear.
Lubricate the front band adjusting screw threads
with petroleum jelly and thread the screw part-way into the case. Be sure the screw turns freely.
Remount the case in Repair Stand C-3750-B after
cleaning and inspection.

DISASSEMBLING OVERRUNNING CLUTCH/ LOW-REVERSE DRUM
If the clutch assembly came out with the low-re­
verse drum, thread two clutch cam bolts into the cam. Then lift the cam out of the drum with the bolts (Fig. 29). Rotate the cam back and forth to ease re­
moval if necessary. Remove the clutch roller and spring assembly from the race afterward.
Fig, 29 Removing Overrunning Clutch From Low- Reverse Drum—32RH
CLEANING AND INSPECTION Clean the overrunning clutch assembly, clutch
cam, low-reverse drum and rear support in solvent.
Dry them with compressed air after cleaning. Inspect condition of each clutch part after cleaning.
Replace the overrunning clutch roller and spring as­ sembly if any rollers or springs are worn or dam­
aged, or if the roller cage is distorted, or damaged.
Replace the cam if worn, cracked or damaged.
Replace the low-reverse drum if the clutch race,
roller surface or inside diameter is scored, worn or damaged. Do not remove the clutch race from the
low-reverse drum under any circumstances. Re­ place the drum and race as an assembly if either component is damaged.
Examine the rear support carefully for wear,
cracks, scoring or other damage. Be sure the support
hub is a snug fit in the case and drum. Replace the support if worn or damaged.

Replace the retainer bushing if worn, scored, or
doubt exists about bushing condition.
Inspect the piston and retainer seal surfaces for
nicks or scratches. Minor scratches can be removed
with crocus cloth. However, replace the piston and/or
retainer if the seal surfaces are seriously scored.
Check condition of the fiber thrust washer and
metal output shaft thrust washer. Replace either
washer if worn or damaged.
Check condition of the seal rings on the input shaft
and clutch retainer hub. Replace the seal rings only
if worn, distorted, or damaged. The input shaft front seal ring is teflon with chamfered ends. The rear
ring is metal with interlocking ends.
Check the input shaft for wear, or damage. Replace
the shaft if worn, scored or damaged in any way.

(b) Note that input shaft front seal ring is teflon
and rear seal ring is metal (Fig. 66). Be sure cham­
fered ends of teflon ring are properly joined and
that ends of rear ring are securely hooked together. Lubricate both rings with light coat of petroleum
jelly after installation.
(3) Lubricate splined end of input shaft and clutch
