COLUMN COMPONENT SERVICE
The Acustar columns have been designed to be ser-
viced as an assembly; less wiring, switches, shrouds,
steering wheel, etc. Also most steering column com-
ponents can be serviced without removing the col-
umn from the vehicle. For additional information on
electrical components refer to Group 8, Electrical.
IGNITION SWITCH SERVICE
TEST AND REPAIR
If the ignition switch effort seems to be excessive
due to binding. Follow the procedure outlined below
to determine the cause.
When service procedures are performed on the
Acustar steering column there are certain areas of
the column that can not be tampered with. If a prob-
lem related to these areas of the steering column are
detected. The entire steering column (less the remov-
able components) should be replaced see (Fig. 1 and
2).

(1) Remove the ignition switch from the steering
column. Refer toGroup 8D Ignition System.
(2) Using a key cylinder, check the turning effort of
the switch.
²If the ignition switch binds look for the following
conditions.
(1) Look for rough areas or flash in the casting and
if found remove with a file (Fig. 2).
(2) Remove the link and slider.
(3) Check the link to see if it has been bent and if
so replace with a new part.
Put the slider in its slot in the sleeve and verify a
loose fit over the length of the slot. If the slider binds
in the slot at any point lightly file the slider until
clearance is achieved.
²If no binding is found.
Lightly file the ramp on the ignition switch, (The
ramp fits into the casting) until binding no longer oc-
curs.
AUTOMATIC TRANSMISSION SHIFTER/IGNITION
INTERLOCK MECHANISM
The automatic transmission Shifter/Ignition Inter-
lock, is a cable operated system. It interconnects the
automatic transmission floor mounted shifter to the
steering column ignition switch (Fig. 1). The system
locks the shifter into the PARK position. The Inter-
lock system is engaged whenever the ignition switch
is in the LOCK or ACCESSORY position. When the
key is in the OFF or RUN position the shifter is un-
locked and will move into any position. The interlock
system also prevents the ignition switch from being
turned to the LOCK or ACCESSORY position (Fig.
2). Unless the shifter is fully locked into the PARK
position.

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.

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
