RECOMMENDED FLUID
The recommended and preferred fluid for 30RH/
32RH transmissions is Mopar ATF Plus, Type 7176.
Mopar Dexron II is acceptable but should only be
used when ATF Plus is not available.
Transmission fluid capacity is approximately 17
pints (7.9 liters). This is the approximate amount of
fluid required to fill the transmission and torque con-
verter after overhaul.
CHECKING FLUID LEVEL AND CONDITION
(1) Position vehicle on flat, level surface. This is
important in obtaining an accurate fluid level check.
(2) To avoid false readings, which could produce
under or over fill condition, do not check level until
fluid is at normal operating temperature.
(3) Shift transmission into Neutral.
(4) Apply parking brakes.
(5) Operate engine at curb idle speed.
WARNING: WHEN PERFORMING UNDERHOOD OP-
ERATIONS WITH THE ENGINE RUNNING, KEEP
YOUR HANDS WELL AWAY FROM HOT OR ROTAT-
ING ENGINE COMPONENTS. DO NOT WEAR
LOOSE ARTICLES OF CLOTHING WHICH COULD
BECOME ENTANGLED IN ENGINE COMPONENTS
OR ACCESSORIES.
(6) Shift transmission through all gear ranges and
back to Neutral (leave engine running).
(7) Clean exterior of dipstick cap and fill tube be-
fore removing transmission dipstick.
(8) Remove dipstick and inspect fluid level.
²Correct level is to FULL mark
²Acceptable level is between ADD and FULL marks
(9) Check fluid condition. Fluid should be dark to
light red in color and free of dirt or debris.
(10) If fluid is discolored or smells burned but
transmission operation was OK, check cooler flow,
flush cooler and lines and change fluid and filter.
Then road test again to confirm proper operation.(11) If fluid is black or dark brown, burned/turned
to sludge, contains large quantities of metal or fric-
tion material particles, transmission will need over-
haul. Especially if problems were evident during
road test and preliminary diagnosis. Fluid cooler
should also be flow tested and flushed if necessary.
GEARSHIFT LINKAGE ADJUSTMENT (YJ)
(1) Check linkage adjustment by starting engine in
Park and Neutral.
(2) Adjustment is OK if engine starts only in park
and Neutral. Adjustment is incorrect if engine starts
in one but not both positions.
(3) If engine starts in any position other than Park
or Neutral, or if engine will not start at all, park/
neutral position switch may be faulty.
(4) Shift transmission into Park.
(5) Raise vehicle.
(6) Check condition of shift rods, bellcrank, bell-
crank brackets and linkage bushings/grommets (Fig.
1). Tighten, repair, replace worn, damaged parts. Do
not attempt adjustment if linkage components are
worn or damaged.
(7) Loosen shift rod trunnion lock bolt or nut. Be
sure upper shift rod slides freely in trunnion (Fig. 1).
Also be sure shift rods and bellcrank rotate freely
and do not bind at any point.
(8) Verify that manual lever is in Park detent
(Fig. 1). Move lever all the way rearward to be sure
it is in Park.
(9) Check for positive engagement of park lock by
attempting to rotate propeller shaft. Shaft will not
turn when park pawl is engaged.
(10) Adjust shift rod trunnion to a obtain free pin
fit in bellcrank arm and tighten trunnion lock bolt or
nut. Prevent shift rod from turning while tightening
bolt or nut. Gearshift linkage lash must be elimi-
nated to obtain proper adjustment. Eliminate lash by
pulling downward on shift rod and pressing upward
on bellcrank.

condenser. The auxiliary cooler is a serviceable com-
ponent and can be repaired if necessary.
The main and auxiliary coolers should be thor-
oughly reverse flushed if a transmission failure
contaminates the fluid. Reverse flushing the cooler
and lines will prevent sludge and particles from
flowing back into the transmission after repair.
The same flushing procedure is used for main and
auxiliary coolers. Pressure equipment is preferred for
reverse flushing. However, reverse flushing can be
performed using hand operated equipment as de-
scribed in the following procedure.
REVERSE FLUSHING PROCEDURE
(1) Disconnect cooler lines at transmission. Refer
to Figure 21 for cooler line fitting identification.
Front fitting is outlet to cooler and rear fitting is in-
let from cooler.
(2) Position drain pan under cooler outlet line to
material flushed through cooler and lines.
(3) Reverse flush cooler using hand operated suc-
tion gun filled with mineral spirits. Insert gun nozzle
(or hose) into cooler inlet (return) line. Then force
mineral spirits through Line and cooler.
(4) Continue reverse flushing until fluid exiting in-
let (pressure) line is clear and free of debris/residue.
Replace radiator if fluid cannot be pumped
through cooler.
(5) Clear flushing materials from cooler and lines
with short pulses of compressed air. Insert air gun
nozzle into cooler inlet (return) line and continue
short pulses of air until all fluid is cleared from
cooler and lines.
(6) Pump one quart of fresh automatic transmis-
sion fluid through cooler and lines before reconnect-
ing cooler lines.
TRANSMISSION COOLER FLOW TESTING
The transmission main and auxiliary coolers
should be flow tested whenever a fluid overheat con-
dition is suspected. An overheat condition is indi-
cated when the fluid changes from the normal red, to
a dark orange, or brown color.
The same method of flow testing is used for both
coolers.Cooler flow is checked by measuring the amount of
fluid flow through the cooler in a 20 second time pe-
riod. The test is performed with the engine running
and transmission in neutral. Fluid is then pumped
through the cooler by the transmission oil pump.
(1) Disconnect cooler inlet line at transmission fitting.
(2) Securely attach hose to end of inlet line and po-
sition line in a one quart test container.
(3) Add extra quart of fluid to transmission.
(4) Use stopwatch to check flow test time.
(5) Shift transmission into neutral and set parking
brake.
(6) Start and run engine at curb idle speed and im-
mediately note cooler flow. Approximately one quart of
fluid should flow into test container in 20 second period.
(7) If cooler flow is intermittent, flows less than
one quart in 20 seconds, or does not flow at all,
cooler is faulty and must be replaced.
SERVICING TRANSMISSION COOLER LINES AND
FITTINGS
Fitting Types
The transmission cooler lines are attached with
quick disconnect fittings.
A flange on the cooler line serves as the sealing
mechanism. The wire retainer clip (Fig. 22), secures
the cooler line in the fitting by this flange. The clip
fits behind the flange to hold the line in place.
Three different fitting styles may be used. Type 1
fittings have the retainer clip exposed (Fig. 22). Type
2 fittings have the retainer clip and fitting body en-
cased in a shrink wrap material (Fig. 23). Type 3 fit-
tings have the retainer clip encased in a metal sleeve
crimped onto the fitting body (Fig. 24).
Fitting Release Tool
A release tool isrequiredto disconnect each of the
fitting types. A plastic tool is clipped directly to one
of the cooler lines on models with the type 2 and 3
fittings. This tool can also be used to disconnect type
1 fittings. The tool is needed to spread the wire re-
tainer clip in each fitting. The clip must be opened in
order to release the cooler line from the fitting.

CONVERTERÐPUMP SEALÐDRIVE PLATE SERVICE
Drive Plate
The drive plate can be replaced or removed for service
access after the transmission is out of the vehicle (Fig. 2).
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 can be replaced or removed
for service access after the transmission has been re-
moved (Fig. 2).
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.
A new torque converter and oil pump are used in
30RH/32RH transmissions built after the 1993
model year. 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 replacement should be-
come necessary, be sure to use the new style con-
verter. The new converter and oil pump are not
interchangeable with previous style parts.The oil pump seal is accessible and can be replaced af-
ter the transmission and torque converter are removed.
Use Remover Tool C-3981B to remove the seal
(Fig. 3). 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 Installer Tool C-4193 to install and seat the
seal (Fig. 4).
Be sure to lubricate the pump seal and converter
hub with transmission fluid before installation.
TRANSMISSION AND CONVERTER INSTALLATION
CAUTION: The transmission oil cooler and lines
must be reverse flushed if repair corrected a prob-
lem that generated sludge and/or debris. Sludge
and metal or friction particles from a gear or clutch
pack failure must be removed before reinstalling
the transmission. This is necessary to avoid re-con-
taminating the repaired transmission. Failure to re-
move sludge or debris from the cooler and lines
will result in a repeat failure and shop comeback.

Inspect the valves and plugs for scratches, burrs,
nicks, or scores. Also inspect the coating on the alu-
minum valves and plugs (Fig. 114). If the coating is
damaged or worn through, the valve (or valve body)
should be replaced.
Aluminum valves and plugs should not be sanded
or polished under any circumstances. However, mi-
nor burrs or scratches on steel valves and plugs can
be removed with crocus cloth but do not round off the
valve or plug edges. Squareness of these edges is vi-
tally important. These edges prevent foreign matter
from lodging between the valves, plugs and bore.
Inspect all the valve and plug bores in the valve
body. Use a penlight to view the bore interiors. Re-place the valve body if any bores are distorted or
scored. Inspect all of the valve body springs. The
springs must be free of distortion, warpage or broken
coils.
Trial fit each valve and plug in its bore to check
freedom of operation. When clean and dry, the valves
and plugs should drop freely into the bores. Valve
body bores do not change dimensionally with use. If
the valve body functioned correctly when new, it will
continue to operate properly after cleaning and in-
spection. It should not be necessary to replace a
valve body assembly unless it is damaged in han-
dling.

(2) Attach dial indicator to converter housing. Po-
sition indicator plunger against input shaft and zero
indicator.
(3) Move input shaft in and out and record read-
ing. End play should be 0.56 - 2.31 mm (0.022 - 0.091
in.).
(4) If end play is incorrect, transmission is incor-
rectly assembled, or output shaft thrust washer
and/or thrust plate are worn and need to be changed.
VALVE BODY INSTALLATION
(1) Install new manual lever shaft seal in case.
Use 15/16 deep well socket to install seal.
(2) Make sure neutral switch hasnotbeen in-
stalled in case. Remove switch if necessary as it will
interfere with valve body installation.
(3) Install new seal rings on accumulator piston
(Fig. 155). Lubricate accumulator piston, seals and
accumulator bore with transmission fluid.(4) Install accumulator piston and spring (Fig. 155)
in case.
(5) Place valve body manual lever in low to move
park lock rod rearward.
(6) Position valve body on case. Work park rod past
sprag and install valve body-to-case bolts finger
tight.
(7) Install park/neutral position switch in case.
Tighten switch to 34 Nzm (25 ft. lbs.) torque.
(8) Align valve body on case (Fig. 156).
(9) Install and tighten valve body-to-case bolts al-
ternately and evenly to 12 Nzm (105 in. lbs.) torque.
Start at center and work outward when tightening
bolts.Do not overtighten valve body bolts. This
could result in distortion and cross leakage af-
ter installation..
(10) Connect converter clutch solenoid wire to case
connector (Fig. 156).
(11) Install new filter on valve body (Fig. 157).
Tighten filter screws to 4 Nzm (35 in. lbs.).
