SERVICE INFORMATION
The steering linkage consists of a pitman arm, drag
link, tie rod, and steering dampener. Adjustment
sleeves are used on the tie rod and drag link for toe
and steering wheel alignment.
Refer to Group 2, Front Suspension and Axle for
additional information.
The tie-rod end ball stud seals should be inspected
during all oil changes.
A damaged ball stud seal requires removal of the
seal. Inspect the tie-rod end ball stud at the throat
opening. Check for lubricant loss, contamination, ball
stud wear or corrosion. If these conditions exist, re-
place the tie-rod. A replacement seal can be installed
if lubricant is in good condition. Otherwise, a com-
plete replacement ball stud end should be installed.
Lubricate the tie-rod end with MOPARtMulti-Mile-
age Lubricant, or equivalent product.
Use a Puller tool for tie rod removal. Failure
to use this tool could damage the ball stud and
seal (Fig. 1).

GENERAL INFORMATION
The AX 15 is a 5-speed, synchromesh, manual
transmission. Fifth gear is an overdrive range with a
ratio of 0.79:1. The shift mechanism is integral and
mounted in the shift tower portion of the adapter
housing (Fig. 1).
An adapter housing is used to attach the transmis-
sion to the transfer case on 4-wheel drive models. A
standard extension housing is used on 2-wheel drive
models.
The AX 15 is used in XJ and YJ models with a
4.0L engine. The AX 15 is designed for use with ei-
ther two-wheel drive or four-wheel drive applica-
tions.
TRANSMISSION IDENTIFICATION
The AX 15 identification code numbers are on the
bottom surface of the transmission gear case (Fig. 2).
The first number is year of manufacture. The sec-
ond and third numbers indicate month of manufac-ture. The next series of numbers is the transmission
serial number.

GENERAL INFORMATION
TRANSMISSION APPLICATION
Chrysler 30RH and 32RH automatic transmissions
are used in XJ/YJ models. Both transmissions are
three speed, automatics with a gear-type oil pump,
two clutches and bands and a planetary gear system
(Fig. 1). The 30RH is used with 2.5L engines and the
32RH is used with 4.0L engines.
TORQUE CONVERTER
A three element, torque converter is used for all
applications. The converter consists of the impeller,
stator, and turbine.
The converter used with all 30RH/32RH transmis-
sions is equipped with a converter clutch. The clutch
is engaged by an electrical solenoid and mechanical
clutch module on the valve body. The solenoid is op-
erated by the powertrain control module.
The impeller is connected to the engine crankshaft
through the front cover which is welded to the impel-
ler. The turbine is splined to the transmission input
shaft and the stator is splined to the transmission re-
action shaft.
The torque converter is a welded assembly and is
not a repairable component. The converter is serviced
as an assembly.
RECOMMENDED FLUID
The recommended (and preferred) fluid for 30RH/
32RH transmissions is Mopar ATF Plus, Type 7176.
Mopar Dexron II can be used but only if 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.
TRANSMISSION IDENTIFICATION
The transmission identification numbers are
stamped on the left side of the case just above the oil
pan gasket surface (Fig. 2). The first set of numbers
is the transmission part number. The next set of code
numbers set is the date of build. The final set of code
numbers represents the transmission serial number.
SPECIFICATIONS AND BAND ADJUSTMENTS
Service specifications and torque values are located
at the end of this group. Refer to the specifications
during service operations.
The band adjustment specifications for 1994
transmissions are different. Refer to the front
and rear band adjustment procedures in the In-
Vehicle Service section for details.
PARTS INTERCHANGEABILITY
The 1994 version of the 30RH (A904) transmission
is similar to previous models in appearance only. The
current 30RH is quite different and interchanging
new/old parts is definitely not recommended. Differ-
ent component dimensions, fluid passages, input/out-
put shafts, cases, bands, valve bodies and governor
assemblies are just a few of the changed items. The
32RH transmission is also different from previous
models and the same recommendations apply here as
well.
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.
TRANSMISSION CONTROLS AND COMPONENTS
The transmission hydraulic control system per-
forms five basic functions, which are:
²pressure supply
²pressure regulation
²flow control
²clutch/band apply and release
²lubrication
Pressure Supply And Regulation
The oil pump generates the fluid working pressure
needed for operation and lubrication. The pump is
driven by the torque converter. The converter is con-
nected to the engine crankshaft through the drive-
plate.
The pressure regulator valve maintains operating
(line) pressure. The regulator valve is located in the
valve body. The amount of line pressure developed is

GENERAL INFORMATION
Automatic transmission problems are generally the
result of:
²poor engine performance
²incorrect fluid level
²incorrect cable/linkage adjustment
²incorrect band adjustment
²incorrect hydraulic control pressure adjustments
²hydraulic component malfunctions
²mechanical component malfunctions.
Begin diagnosis by checking the easily accessible
items such as fluid level, fluid condition and control
linkage adjustment. A road test will determine if fur-
ther diagnosis is necessary.
Procedures outlined in this section should be per-
formed in the following sequence to realize the most
accurate results:
²Preliminary diagnosis
²Check fluid Level and condition
²Check control linkage Adjustment
²Road test
²Stall test
²Hydraulic pressure test
²Air pressure tests
²Leak Tests
²Analyze test results and consult diagnosis charts
PRELIMINARY DIAGNOSIS
Two basic procedures are required. One procedure
for vehicles that are driveable and an alternate pro-
cedure for disabled vehicles (will not back up or
move forward).
Vehicle Is Driveable
(1) Check fluid level and condition.
(2) Adjust throttle cable and gearshift linkage if
complaint was based on delayed, erratic, or harsh
shifts.
(3) Road test vehicle and note transmission operat-
ing characteristics.
(4) Perform stall test if complaint is based on slug-
gish, low speed acceleration or abnormal throttle
opening needed to maintain normal speeds with
properly tuned engine.
(5) Perform hydraulic pressure tests.(6) Perform air pressure test to check clutch-band
operation.
Vehicle Is Disabled
(1) Check fluid level and condition.
(2) Check for broken, disconnected throttle link-
age.
(3) Check for cracked, leaking cooler lines, or
loose, missing pressure port plugs.
(4) Raise vehicle, start engine, shift transmission
into gear and note following:
(a) If propeller shafts turn but wheels do not,
problem is with differential or axle shafts.
(b) If propeller shafts do not turn and transmis-
sion is noisy, stop engine. Remove oil pan, and
check for debris. If pan is clear, remove transmis-
sion and check for damaged drive plate, converter,
oil pump or input shaft.
(c) If propeller shafts do not turn and transmis-
sion is not noisy, perform hydraulic pressure test to
determine if problem is a hydraulic or mechanical.
FLUID LEVEL AND CONDITION
(1) Position vehicle on level surface. This is impor-
tant 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) Clean dipstick filler cap and tube before remov-
ing dipstick.
(7) Remove dipstick and inspect fluid level.
²Correct level is to FULL mark
²Acceptable level is between ADD and FULL marks
