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 used for two and four-wheel
drive applications.
TRANSMISSION IDENTIFICATION
The AX 15 identification code numbers are on the
bottom surface of the transmission gear case (Fig. 2).
Fig. 1 AX 15 Manual Transmission
Fig. 2 Identification Code Number Location
JAX 15 MANUAL TRANSMISSION 21 - 33

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.
TRANSMISSION SHIFT PATTERN
The AX 15 shift pattern is shown in Figure 3. First
and second and third and fourth gear ranges are in
line for improved shifting. Fifth and reverse gear
ranges are also in line at the extreme right of the
pattern (Fig. 3).
The AX 15 is equipped with a reverse lockout
mechanism. The shift lever must be moved through
the Neutral detent before making a shift to reverse.
TRANSMISSION LUBRICANT
Recommended lubricant for AX 15 transmissions is
Mopar 75W-90, API Grade GL-5 gear lubricant, or
equivalent.
Correct lubricant level is from the bottom edge, to
no more than 6 mm (1/4 in.) below the bottom edge of
the fill plug hole.
Approximate dry fill lubricant capacity is:
²3.10 liters (3.27 qts.) in 4-wheel drive models
²3.15 liters (3.32 qts.) in 2-wheel drive models
TRANSMISSION SWITCH AND PLUG LOCATIONS
The fill plug is at the driver side of the gear case
(Fig. 4).
The drain plug and backup light switch are on the
passenger side of the gear case (Fig. 5).
TRANSMISSION GEAR RATIOS
AX 15 gear ratios are:
First gear - 3.83:1
Second gear - 2.33:1
Third gear - 1.44:1
Fourth gear - 1.00:1
Fifth gear - 0.79:1
Reverse - 4.22:1
SERVICE DIAGNOSIS
LOW LUBRICANT LEVEL
A low transmission lubricant level is generally the
result of a leak, inadequate lubricant fill, or an incor-
rect lubricant level check.
Leaks can occur at the mating surfaces of the gear
case, intermediate plate and adapter or extension
housing, or from the front/rear seals. A suspected
leak could also be the result of an overfill condition.
Leaks at the rear of the extension or adapter hous-
ing will be from the housing oil seals. Leaks at com-
ponent mating surfaces will usually be the result of
inadequate sealer, gaps in the sealer, incorrect bolt
tightening, or use of a non-recommended sealer.
A leak at the front of the transmission will be from
either the front bearing retainer or retainer seal. Lu-
bricant may be seen dripping from the clutch housing
after extended operation. If the leak is severe, it may
also contaminate the clutch disc causing slip, grab
and chatter.
Transmissions filled from air or electrically pow-
ered lubricant containers can be underfilled. This

GENERAL INFORMATION
Automatic transmission problems are generally a
result of:
²poor engine performance
²incorrect fluid level
²incorrect throttle valve cable 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 test
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 linkage.
(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 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.
21 - 70 30RH/32RH TRANSMISSION DIAGNOSISJ

clutch is slipping. Similarly, if slippage occurs in any
two forward gears, the rear clutch is slipping.
Applying the same method of analysis, note that
both clutches are applied in D range third gear only.
If the transmission slips in third gear, either the
front clutch or the rear clutch is slipping. By select-
ing another gear which does not use one of these
units, the slipping clutch can be determined.
Although road test analysis will help determine the
slipping unit, the actual cause of a malfunction may
not be determined until hydraulic and air pressure
tests are performed. Practically any condition can be
caused by leaking hydraulic circuits or sticking
valves. Unless the problem is an obvious one, do not
remove and disassemble the transmission until hy-
draulic and air pressure tests have been performed.
HYDRAULIC PRESSURE TEST
Hydraulic test pressures range from a low of one
psi (6.895 kPa) governor pressure, to 300 psi (2068.5
kPa) at the rear servo pressure port in reverse.
Use 100 psi Pressure Gauge C-3292 to check pres-
sure at the accumulator, front servo, governor and
fluid cooler line. Use 300 psi Gauge C-3293 to check
pressure at the rear servo. The 300 psi gauge can be
used at any other port when more than one gauge is
required for testing.
PRESSURE TEST PORT LOCATIONS
There are pressure test ports at the accumulator,
front servo, rear servo and governor.
Line pressure is checked at the accumulator port
on the right side of the case (Fig. 4). The front servo
release pressure port is at the right side of the case
just behind the filler tube opening (Fig. 4).
The rear servo pressure port is at the right rear of
the transmission case (Fig. 5).
On4x2models, the governor pressure port is at
the left side of case at the transmission rear (Fig. 5).
On4x4transmissions, the test port is in the driver
side of the adapter housing (Fig. 6).
PRESSURE TEST PROCEDURE
Connect a tachometer to the engine. Position the
tachometer so it can be observed from under the ve-
hicle. Raise the vehicle on a hoist that will allow the
wheels to rotate freely.
Test One-Transmission In 1 Range
This test checks pump output, pressure regu-
lation, and condition of the rear clutch and
rear servo circuits. Use both test gauges for
this test
(1) Connect Test Gauge C-3292 to line pressure
port and Test Gauge C-3293 to rear servo port (Figs.
4-6).
(2) Disconnect throttle and gearshift rods at trans-
mission.
(3) Start and run engine at 1000 rpm.
(4) Move valve body selector lever forward into 1
range.
(5) Read pressures on both gauges as transmission
throttle lever is moved from full forward to full rear-
ward position.
(a) Line pressure should be 54-60 psi (372-414
kPa) with throttle lever forward and gradually in-
crease to 90-96 psi (620-662 kPa) as lever is moved
rearward.
(b) Rear servo pressure should be same as line
pressure within 3 psi.
