GENERAL INFORMATION
The AX 4 is a four speed manual transmission. The
AX 5 is a five speed manual transmission. Fifth gear
in the AX 5 is an overdrive range. The shift mecha-
nism in both models is integral and mounted in theshift tower portion of the adapter housing (Fig. 1).
The AX 4/5 is used for 2.5L engine applications.

JTRANSMISSION AND TRANSFER CASE 21 - 1

TRANSMISSION IDENTIFICATION
The AX 4/5 identification code is on the bottom sur-
face of the transmission case near the fill plug (Fig. 2).
The first number is year of manufacture. The second
and third numbers indicate month of manufacture. The
next series of numbers is the transmission serial num-
ber.
GEAR RATIOS
Gear ratios for the AX 4 and AX 5 are as follows:
²First gear: 3.93:1
²Second gear: 2.33:1
²Third gear: 1.45:1
²Fourth gear: 1.00:1
²Fifth gear (AX 5): 0.85:1
²Reverse gear: 4.74:1
SHIFT PATTERN
The AX 4/5 first through fourth gear shift pattern
is in a conventional H configuration. On the AX 5,
fifth gear is up and to the right and reverse gear is
down and to the right (Fig. 3).
RECOMMENDED LUBRICANT
Recommended lubricant for AX 4/5 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.
The fill plug is at the passenger side of the adapter
housing Fig. 4). The drain plug is at the bottom of
the case.
Approximate dry fill lubricant capacity is 3.3 liters
(3.5 qts.).
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 adaptor 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 probably 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 powered
lubricant containers can be underfilled. This generally

Fig. 3 AX 4/5 Shift Pattern
Fig. 4 Fill Plug Location
21 - 2 AX 4/5 MANUAL TRANSMISSIONJ

happens when the container delivery mechanism is im-
properly calibrated. Always check the lubricant level af-
ter filling to avoid an under fill condition.
A correct lubricant level check can only be made
when the vehicle is level; use a drive-on hoist to en-
sure this. Also allow the lubricant to settle for a
minute or so before checking. These recommenda-
tions will ensure an accurate check and avoid an un-
der-or-overfill condition.
HARD SHIFTING
Hard shifting is usually caused by a low lubricant
level, improper or contaminated lubricants, compo-
nent damage, incorrect clutch adjustment, or by a
damaged clutch pressure plate or disc.
Substantial lubricant leaks can result in gear, shift
rail, synchro and bearing damage. If a leak goes un-
detected for an extended period, the first indications
of a problem are usually hard shifting and noise.
Incorrect or contaminated lubricants can also con-
tribute to hard shifting. The consequence of using
non-recommended lubricants is noise, excessive wear,
internal bind and hard shifting.
Improper clutch release is a frequent cause of hard
shifting. Incorrect adjustment or a worn, damaged
pressure plate or disc can cause incorrect release. If
the clutch problem is advanced, gear clash during
shifts can result.
Worn or damaged synchro rings can cause gear clash
when shifting into any forward gear. In some new or re-
built transmissions, new synchro rings may tend to
stick slightly causing hard or noisy shifts. In most
cases, this condition will decline as the rings wear-in.
TRANSMISSION NOISE
Most manual transmissions make some noise dur-
ing normal operation. Rotating gears generate a mild
whine that is audible but only at extreme speeds.
Severe, highly audible transmission noise is gener-
ally the result of a lubricant problem. Insufficient,
improper, or contaminated lubricant will promote
rapid wear of gears, synchros, shift rails, forks and
bearings. The overheating caused by a lubricant
problem, can also lead to gear breakage.
TRANSMISSION REMOVAL
(1) Shift transmission into first or third gear. Then
raise vehicle on hoist.
(2) Support engine with adjustable jack stand. Po-
sition wood block between jack and oil pan to avoid
damaging pan.
(3) Disconnect necessary exhaust system components.
(4) Remove skid plate.
(5) Disconnect rear cushion and bracket from
transmission (Fig. 5).
(6) Remove rear crossmember.
