(3) Position the steering column assembly in the
vehicle. Align the steering column assembly mounting
bracket slots on the brake pedal bracket attaching
studs (Fig. 13). Install, but loose assemblethe two
upper column bracket, washers and nuts.
(4) Make sure the front wheels are in the straight-
ahead position. Align and assemble the upper steering
coupler to lower steering coupler. Install the upper to
lower steering coupler retaining bolt and nut. Torque
the retaining bolt nut to 28 N Im (250 in. lbs.). Be sure
to install the upper to lower steering coupler
retaining bolt retention pin (Fig. 6). (5) Install the buttons which retain the multi func-
tion switch wiring harness to the steering column.
Connect the multi-function switch wiring harness con-
nector to the multi-function switch. Torque the connec-
tor retaining bolt to 2 N Im (17 in. lbs) usin ga7mm
socket (Fig. 8). (6) Install the upper fixed shroud onto the steering
column assembly. (7) Be sure both breakaway capsules are fully seated
in the slots of the steering column upper support
bracket. Torque the 2 upper steering column assembly
to support bracket nuts to 12 N Im (105 in. lbs.). Torque
the 2 lower steering column assembly to mounting
bracket nuts to 12 N Im (105 in. lbs.).
(8) Complete the wiring harness connections to the
remaining steering column switches (Fig. 9). Install
the lower fixed shroud onto the steering column.
(9) Route the PRNDL actuator assembly under left
steering column wing and along left side of steering
column. Insert the flange of the PRNDL actuator steering
column insert into the steering column jacket (Fig. 7).
Squeeze the legs of the steering column insert together
and install tabs under steering column jacket. Engage
lock bar to secure the actuator assembly into the steering
column jacket (Fig. 7). (10) Hook the PRNDL actuator cable eyelet to the
steering column actuator arm (Fig. 7). Move the shift
lever to neutral, check pointer location, should indicate neutral. If pointer does not indicate neutral adjust actua-
tor with tool (Fig. 14) to center pointer on N (Neutral) and
then check pointer location in other gears.
(11) Install the lock housing shrouds. The shroud
fasteners are Torx-headscrews. Install the tilt lever
(if equipped). (12) Install the lower dash panel cover.
(13) For steering wheel installation with speed con-
trol refer to Group 8 Electrical. For non-speed control,
place the steering wheel on the steering column shaft
with the master splines aligned. Install the steering
wheel to column shaft retaining nut. Tighten retaining
nut to 61 N Im (45 ft. lbs.) torque. Do not force the
steering wheel onto the column shaft by driving
it on with a heavy object. Pull steering wheel
down onto column shaft using ONLY the steering
wheel retaining nut.
(14) For vehicles equipped with a column shift. Pass
the transmission shift cable through its mounting bracket
on the steering column assembly. Connect the transmis-
sion shift cable to the shift lever on the steering column
assembly. Install the shift cable to mounting bracket
retaining clip (Fig. 2). The grommet must be installed
in the shift lever (Fig. 11) before the cable is in-
serted into the grommet. Use MopartMultipurpose
Lubricant, or an equivalent product, to aid installation of
shift link rod into grommet.
(15) Re-adjust the transmission shift linkage.
Whenever the steering column is loosened or
removed, the shift linkage MUST be adjusted and
tested. Refer to Group 21 Transmission for the shift
linkage adjustment procedure.

tioning properly.
IN-CAR TRANSAXLE DISASSEMBLE/ASSEMBLE
The following items can be serviced without remov-
ing the transaxle from the vehicle:
² Gear shift housing
² Synchronizers
² Intermediate shaft speed gears
² Input shaft
² Reverse idler gear and shaft
² Shift forks and pads
² Shift rails ²
Roller detents
² Speedometer pinion
² All external covers
Observe following procedure:
(1) Disconnect negative cable from battery.
(2) Remove both shift cables from shift cover levers.
(3) Remove left front wheel and tire assembly and
left splash shield. (4) Place drain pan under transaxle and remove
transaxle rear end cover. (5) Push out the fifth fork roll pin and slide the fifth
fork and synchronizer sleeve off the rail/hub. (6) Remove the fifth hub snap ring, hub assembly
and speed gear. (7) Remove fifth gear nut and fifth input gear.
(8) Remove the bearing retainer plate, interlock
plate and shuttles.
CAUTION: Before removing the gearshift housing
assembly, reverse the lock pin (so the long end is
down) and insert lock pin into the same threaded
hole. This procedure will save time when the gear
shift housing assembly is reinstalled. (9) Remove selector shaft housing bolts (note the two
pilot bolts) and remove housing. (10) Remove roller detents and springs, noting that
the rollers align with the shift rails. (11) Push out the 1-2 and 3-4 lug roll pins, remove
the reverse pivot lever and fifth rail C-Clip. If a roll
pin or C-Clip falls, be sure to remove it from the
bottom of the case. (12) Pull out the fifth shift rail and remove the fifth
shift lug and interlock pin. If the pin falls, be sure to
remove it from the bottom of the case. (13) Remove the intermediate shaft ball bearing
snap ring and the bearing support plate. (14) Remove reverse shift rail and lug assembly.
(15) Remove the reverse idler shaft and gear assem-
bly. (16) Rotate the 1-2 shift lug and rail, and 3-4 shift
lug towards the front of the vehicle. (17) Firmly grasp both the input and intermediate
shaft assemblies and pull them out of the transmission
with the 1-2 and 3-4 shift rails, lugs and forks. The differential assembly can only be serviced
by removing the complete transaxle from the
vehicle because bearing preload must be reset. The components listed in the first paragraph can now
be serviced. Refer to the appropriate subassembly
recondition section.
To reassemble the transaxle in the vehicle, reverse
the above procedure using the proper sealants. Fill the
transaxle with SAE 5W-30 engine oil to the bottom of
the fill hole in the end cover.

CAUTION: If the vehicle is equipped with two oil
coolers (one in the radiator tank, one in front of the
radiator) they must be flushed separately. Do not
attempt to flush both coolers at one time. (1) Disconnect the cooler lines at the transmission.
(2) Using a hand suction gun filled with mineral
spirits, reverse flush the cooler. Force mineral spirits
into the From Cooler line of the cooler (Fig. 7) and
catch the exiting spirits from the To Coolerline.
Observe for the presence of debris in the exiting
fluid. Continue until fluid exiting is clear and free
from debris.
(3) Using compressed air in intermittent spurts,
blow any remaining mineral spirits from the cooler,
again in the reverse direction. (4) To remove any remaining mineral spirits from
the cooler, one (1) quart of automatic transmission
fluid should be pumped through the cooler before re-
connecting. (5) If at any stage of the cleaning process, the
cooler does not freely pass fluid, the cooler must be
replaced.
OIL COOLER FLOW CHECK
After the new or repaired transmission has been
installed, filled to the proper level with automatic
transmission fluid. The flow should be checked using
the following procedure: (1) Disconnect the From coolerline at the trans-
mission and place a collecting container under the
disconnected line. (2) Run the engine at curb idle speed , with the
shift selector in neutral. (3) If the fluid flow is intermittent or it takes more
than 20 seconds to collect one quart of automatic
transmission fluid, the cooler should be replaced. CAUTION: With the fluid set at the proper level,
fluid collection should not exceed (1) quart or inter-
nal damage to the transmission may occur.
(4) If flow is found to be within acceptable limits,
reconnect the cooler line. Then fill transmission to
the proper level, using the approved type of auto-
matic transmission fluid.
TRANSAXLE REMOVAL AND INSTALLATION
Transaxle removal does NOT require engine re-
moval. See Group 7-Cooling, to drain engine cooling sys-
tem and remove coolant return extension (3.0 liter
engine only). (1) The transaxle and torque converter must be re-
moved as an assembly; otherwise, the torque con-
verter drive plate, pump bushing or oil seal may be
damaged. The drive plate will not support a load;
therefore, none of the weight of the transaxle should
be allowed to rest on the drive plate during removal. (2) Disconnect negative battery cable.
(3) Disconnect transaxle shift linkage.
(4) Install engine support fixture and support en-
gine (Fig.1).
(5) Remove upper bell housing upper bolts.
(6) Raise vehicle. Remove front wheels. Refer to
Suspension, Group 2 to remove wheel hub nut and
both drive shafts. (7) Remove left plastic splash to gain access to the
transaxle (Fig. 2). (8) Remove torque converter dust shield to gain ac-
cess to torque converter bolts (Fig. 3). (9) Mark torque converter and drive plate with
chalk, for reassembly. Remove torque converter
mounting bolts. (10) Disconnect electrical connectors at transmis-
sion range switch and Park/Neutral Position Switch
(Fig. 4).
