driven by the torque converter. The converter is con-
nected to the engine crankshaft through the drive-
plate.
The pressure regulator valve maintains line pres-
sure. The regulator valve is located in the valve body.
The amount of line pressure developed is controlled
by throttle pressure, which is dependent on the de-
gree of throttle opening.
The governor valve is operated by the transmission
output shaft. Governor pressure increases approxi-
mately in proportion to vehicle speed.
The throttle valve determines line pressure and
shift speed. The throttle valve also controls upshift
and downshift speeds by regulating pressure in con-
junction with throttle position.
Shift Valves
The manual valve is operated by the gearshift link-
age and provides the operating range selected by the
driver.
The 1-2 shift valve provides automatic 1-2 or 2-1
shifts and the 2-3 shift valve provides automatic 2-3
or 3-2 shifts. The kickdown valve provides forced 3-2
or 3-1 downshifts depending on vehicle speed. Down-
shifts occur when the throttle is opened beyond
downshift detent position which is just before wide
open throttle.
The 2-3 valve throttle pressure plug provides 3-2
downshifts with varying throttle openings and de-
pending on vehicle speed. The 1-2 shift control valve
transmits 1-2 shift pressure to the accumulator pis-
ton to control kickdown band capacity on 1-2 upshifts
and 3-2 downshifts.The shuttle valve has two functions. First is fast
front band release and smooth engagement during
lift-foot 2-3 upshifts. The second is to regulate front
clutch and band application during 3-2 downshifts.
Clutches-Bands-Servos-Accumulator
The front/rear clutch pistons and servo pistons are
actuated by line pressure. When line pressure is re-
moved, the pistons are released by spring tension.
On 2-3 upshifts, the front servo piston is released
by spring tension and hydraulic pressure. The accu-
mulator controls hydraulic pressure on the apply side
of the front servo during 1-2 upshifts and at all
throttle openings.
Converter Clutch Controls
Converter clutch operation is controlled by the
power train control module, and by the solenoid and
clutch module on the valve body. The solenoid is op-
erated by a relay on the engine compartment side of
the dash panel.
Activating the solenoid opens a vent allowing fluid
to flow into the clutch module. When line pressure
exceeds tension of the module valve springs, the
module valves open. This allows fluid to be chan-
neled to the converter clutch through the reaction
shaft support and transmission shaft.
Gearshift And Park Lock Controls
The gearshift lever provides six operating positions:
Park (P), Reverse (R), Neutral (N), and the D, 2 and
1 forward drive ranges.
Manual 1 position provides first gear only. Overrun
braking occurs in 1 range when the throttle is re-
leased. Upshifts are not provided in 1 range.
Manual 2 range provides first and second gear. A
1-2 upshift will take place but a 2-3 upshift will not
occur.
D position provides 1-2, 2-3 upshifts and 3-2 and
3-1 downshifts.
Park position allows the park rod to move the park
pawl into engagement with the park gear. This pre-
vents rotation of the transmission output shaft. The
park lock mechanism is only engaged when the shift
lever is in the Park detent.
A park/neutral position switch controls engine
starting. The switch is designed to allow engine
starts only in park or neutral positions.

CONVERTER STALL TEST
Stall testing involves determining maximum engine
rpm obtainable at full throttle with the rear wheels
locked and the transmission in D range. This test
checks the holding ability of the converter overrun-
ning clutch and both of the transmission clutches.
When stall testing is completed, refer to the Stall
Speed Specifications chart and Stall Speed Diagnosis
guides.
WARNING: NEVER ALLOW ANYONE TO STAND IN
FRONT OF THE VEHICLE DURING A STALL TEST.
ALWAYS BLOCK THE FRONT WHEELS AND APPLY
THE SERVICE AND PARKING BRAKES DURING
THE TEST.
STALL TEST PROCEDURE
(1) Connect tachometer to engine.
(2) Check and adjust transmission fluid level.
(3) Start and run engine until transmission fluid
reaches normal operating temperature.
(4) Block front wheels.
(5) Fully apply service and parking brakes.
(6) Open throttle completely and record maximum
engine rpm registered on tachometer. It will take
from 3 to 10 seconds to reach maximum rpm. How-
ever, once maximum rpm has been achieved,do not
hold wide open throttle for more than 5 sec-
onds.
CAUTION: Stalling the converter causes a rapid in-
crease in fluid temperature. To avoid fluid overheat-
ing, hold wide open throttle for no more than 5
seconds after reaching peak rpm. In addition, if
more than one stall test is required, run the engine
at 1000 rpm with the transmission in Neutral for at
least 20 seconds to cool the fluid.
(7) Stall speeds should be in 1700-2150 rpm range.
CAUTION: If engine exceeds 2150 rpm, release ac-
celerator pedal immediately as transmission clutch
slippage is occurring.
(8) Shift transmission into Neutral. Run engine for
20-30 seconds at 1000 rpm to cool fluid. Then stop
engine, shift transmission into Park and release
brakes.
(9) Refer to Stall Test Diagnosis.
STALL TEST DIAGNOSIS
Stall Speed Too Low
Low stall speeds with a properly tuned engine in-
dicate a torque converter overrunning clutch prob-
lem. The condition should be confirmed by road
testing prior to converter replacement.The converter overrunning clutch is slipping when
stall speeds are 250 to 350 rpm below specified min-
imum.
A converter overrunning clutch failure will result
in sluggish acceleration in all speed ranges. It will
also require greater than normal throttle opening to
maintain cruising speeds.
Stall Speed Too High
If stall speed exceeds 2150 rpm, transmission
clutch slippage is occurring.
Stall Speed Normal But Acceleration Is Sluggish
If stall speeds are within specified range but abnor-
mal throttle opening is required for acceleration, or
to maintain cruise speeds, the converter overrunning
clutch is seized. The torque converter will have to be
replaced.
Converter Noise During Test
A whining noise caused by fluid flow is normal dur-
ing a stall test. However, loud metallic noises indi-
cate a damaged converter. To confirm that noise is
originating from the converter, operate the vehicle at
light throttle in Drive and Neutral on a hoist and lis-
ten for noise from the converter housing.
AIR PRESSURE TEST
Air pressure testing can be used to check clutch
and band operation with the transmission either in
the vehicle, or on the work bench as a final check af-
ter overhaul.
Air pressure testing requires that the oil pan and
valve body be removed from the transmission.
The servo and clutch apply passages are shown in
Figure 8.
Air Test Procedure
(1) Place one or two fingers on the clutch housing
and apply air pressure through front clutch apply
passage (Fig. 8). Piston movement can be felt and a
soft thud heard as the clutch applies.
(2) Place one or two fingers on the clutch housing
and apply air pressure through rear clutch apply
passage (Fig. 8). Piston movement can be felt and a
soft thud heard as the clutch applies.
(3) Apply air pressure to the front servo apply pas-
sage. The servo rod should extend and cause the
band to tighten around the drum. Spring tension
should release the servo when air pressure is re-
moved.
(4) Apply air pressure to the rear servo apply pas-
sage. The servo rod should extend and cause the
band to tighten around the drum. Spring tension
should release the servo when air pressure is re-
moved.

RECOMMENDED FLUID
Recommended (and preferred) fluid for 30RH/32RH
transmissions is Mopar ATF Plus, type 7176.
Dexron II is not really recommended and should
only be used when ATF Plus is not available.
FLUID LEVEL CHECK
Transmission fluid level should be checked monthly
under normal operation. If the vehicle is used for
trailer towing or similar heavy load hauling, check
fluid level and condition weekly.
Fluid level is checked with the engine running at
curb idle speed, the transmission in Neutral and the
transmission fluid at normal operating temperature.
FLUID LEVEL CHECK PROCEDURE
(1) Transmission fluid must be at normal operating
temperature for accurate fluid level check. Drive ve-
hicle if necessary to bring fluid temperature up to
normal hot operating temperature of 82ÉC (180ÉF).
(2) Position vehicle on level surface. This is ex-
tremely important for accurate fluid level check.
(3) Start and run engine at curb idle speed.
(4) Apply parking brakes.
(5) Shift transmission momentarily into all gear
ranges. Then shift transmission back to Neutral.
(6) Clean top of filler tube and dipstick to keep dirt
from entering tube.
(7) Remove dipstick and check fluid level as fol-
lows:
(a) Dipstick has three fluid level indicator levels
(Fig. 1) which are a MIN dot, an OK crosshatch
area, and a MAX fill arrow.
(b) Correct maximum level is to MAX arrow
mark. Correct acceptable level is to OK mark in
crosshatch area.
(c) Incorrect level is at or below MIN dot.
(d) If fluid is low, add only enough Mopar ATF
Plus restore correct level. Do not overfill.CAUTION: Do not overfill the transmission. Overfill-
ing may cause leakage out the pump vent which
can be mistaken for a pump seal leak. Overfilling
will also cause fluid aeration and foaming as the ex-
cess fluid is picked up and churned by the gear
train. This will reduce fluid life significantly.
FLUID AND FILTER REPLACEMENT
NORMAL CHANGE INTERVAL
The fluid and filter should be changed (and the
bands adjusted) at recommended maintenance inter-
vals, or whenever the transmission has been disas-
sembled for any reason.
Refer to the Driveline section in Group O, Lubrica-
tion and Maintenance for recommended change inter-
vals. Refer to the fluid/filter replacement and band
adjustment procedures in this section.
SEVERE USAGE CHANGE INTERVAL
Under severe usage, the fluid and filter should be
changed and the bands adjusted at 12,000 mile (19
000 Km) intervals.
Severe usage is defined as:
(a) More than half of vehicle operation occurs in
heavy city traffic during hot weather (above 90É F).
(b) Vehicle is used for taxi, police, limousine, or
similar commercial operation.
Fig. 1 Fluid Level Marks On Transmission Dipstick
J30RH/32RH IN-VEHICLE SERVICE 21 - 99

(c) Vehicle is used for trailer towing or heavy
load hauling.
FLUID/FILTER REPLACEMENT PROCEDURE
(1) Raise vehicle.
(2) Remove oil pan and drain fluid.
(3) Clean oil pan and pan magnet. Then clean re-
maining gasket material from gasket surface of
transmission case.
(4) Remove fluid filter screws and remove filter.
(5) Position new filter on valve body and install fil-
ter screws. Tighten screws to 4 Nzm (35 in. lbs.)
torque.
(6) Adjust rear band at this time if required.
(7) Position new gasket on oil pan and install pan
on transmission. Tighten pan bolts to 150 in. lbs. (17
Nzm) torque.
(8) Adjust front band at this time if required.
(9) Lower vehicle and refill transmission with Mo-
par ATF Plus, type 7176 fluid.
REFILLING AFTER OVERHAUL OR FLUID/FILTER
CHANGE
The most effective way to avoid overfilling after a
fluid change or overhaul is as follows:
(1) Remove dipstick and insert clean funnel in
transmission fill tube.
(2) Add following initial quantity of Mopar ATF
Plus to transmission:
(a) If only fluid and filter were changed, add3
pints (1-1/2 quarts)of ATF Plus to transmission.
(b) If transmission was completely overhauled
and torque converter was replaced or drained, add
10 pints (5 quarts)of ATF Plus to transmission.
(3) Apply parking brakes.
(4) Start and run engine at normal curb idle speed.
(5) Apply service brakes, shift transmission
through all gear ranges then back to Neutral, and
leave engine running at curb idle speed.
(6) Remove funnel, insert dipstick and check fluid
level. Add only enough fluid to bring level toMIN
dot mark on dipstick.
(7) Drive vehicle until transmission fluid is at nor-
mal operating temperature. Then recheck fluid level
as described in next step.
(8) Leave engine running at curb idle speed, shift
into Neutral, and check fluid level again. This time,
add just enough fluid to bring level up toMAX ar-
row mark but do not overfill.
(9) When fluid level is correct, shut engine off, re-
lease park brake, remove funnel, and reseat dipstick
in fill tube.
SHIFT 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,
bellcrank brackets and linkage bushings/grommets
(Fig. 2). Tighten, repair, replace worn, damaged
parts. Do not attempt adjustment if linkage compo-
nents are worn or damaged.
(7) Loosen shift rod trunnion lock bolt or nut. Be
sure upper shift rod slides freely in trunnion (Fig. 2).
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.
2). 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.
(11) Confirm proper adjustment by starting engine
in Park and Neutral. Engine should start in these
positions only.If engine starts in any position
other than Park or Neutral, adjustment is in-
correct or neutral switch is faulty.
(12) Lower vehicle and verify that steering lock op-
erates correctly.
SHIFT CABLE ADJUSTMENT (XJ)
(1) Shift transmission into Park.
(2) Raise vehicle.
(3) Release cable adjuster clamp to unlock cable
(Figs. 3 and 4). Clamp is at transmission end of ca-
ble.

(7) Move shift lever back to Park and check igni-
tion switch operation. You should be able to turn
switch to Lock position and shift lever release button/
lever should not move.
THROTTLE VALVE CABLE ADJUSTMENT (XJ/YJ)
The throttle valve cable controls throttle pressure
and kickdown on 30RH/32RH transmissions (Fig. 5).
Correct cable adjustment is important to proper
shifting. The cable positions the throttle valve which
controls shift speed, shift quality and part throttle
downshift sensitivity. If the setting is incorrect, shift
quality and shift speeds will be unsatisfactory.
