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).

If the torque converter has been replaced, refer
to Torque Converter Clutch Break-in Procedure
in this section. This procedure will reset the transmission control module break-in status.
Failure to perform this procedure may cause
transaxle shutter. Check and/or adjust gear shift cable.
Refill transaxle with MOPAR tATF PLUS (Auto-
matic Transmission Fluid) Type 7176.

TRANSMISSION RANGE SWITCH
The transmission range switch is the white switch
located on the front of the transaxle, just above the
transaxle oil pan. CAUTION: Switch seal washer must be seated prop-
erly before tightening switch. Failure to do so may
result in leakage of transmission fluid (Fig. 6).
PARK/NEUTRAL POSITION SWITCH
The Park/Neutral Position Switch is the black
switch located to the right of the transmission range
switch.
CAUTION: Switch seal washer must be seated prop-
erly before tightening switch. Failure to do so may
result in leakage of transmission fluid (Fig. 7).
SPEED SENSOR-INPUT
CAUTION: When disconnecting speed sensor con-
nector, be sure that the weather seal does not fall
off or remain in old sensor.
The input speed sensor is located to the right of the
manual shift lever.

HYDRAULIC SYSTEMS
The power convertible top hydraulic system con-
sists of;
² Two hydraulic cylinders
² Hydraulic lines
² Electric hydraulic pump and reservoir
² Dual relays
HYDRAULIC SYSTEM TESTS
The convertible top will raise slowly or make ab-
normal noise if the hydraulic fluid level is low. (1) Remove sling well and floor cover.
(2) With the top up and latched, remove the reser-
voir fill plug. (3) Visually inspect fluid level. If low, inspect for
leak in hydraulic system. (4) Repair or replace components, as necessary.
(5) Fill reservoir with Dexron tII, Type A, auto-
matic transmission fluid to the bottom of the fill
hole. (6) Replace fill plug and lower top.
(7) Raise top and verify fluid level.
(8) Install sling well and floor cover.
