(7) Remove or install anti-rotational link (or anti-
hop damper) from crossmember bracket. Do not re-
move bracket from transaxle .
(8) Refer to Group 2 Suspension, to remove or
install both drive shafts. When removing or installing the transaxle, it
may be helpful to use locating pins in place of the
top transaxle to engine bolts (Fig. 3).
Make the locating pins from two stock (transaxle
case to engine block) bolts as follows: Using a hacksaw,
remove bolt heads, cut slot in end of bolts for a screw
driver, and remove burrs with a grinding wheel. Install the locating pins into the engine block and
proceed with transaxle installation. After transaxle is
in place, install bolts and remove locating pins before
removing transmission jack.

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.

gage compartment. If light is visible through a nor-
mally sealed location, water could enter through the
opening.
PRESSURIZED LEAK TEST METHOD
When a water leak into the passenger compartment
can not be detected by water testing, pressurize the
passenger compartment and soap test exterior of the
vehicle. To pressurize the passenger compartment,
close all doors and windows, start engine, and set
heater control to high blower in HEAT position. If
engine can not be started, connect a charger to the
battery to assure adequate voltage to the blower. With
interior pressurized, apply dish detergent solution to
suspected leak area on the exterior of the vehicle.
Apply detergent solution with spray device or soft
bristle brush. If soap bubbles occur at a body seam,
joint, seal or gasket the leak entry point could be at
that location.
WIND NOISE
Wind noise is the result of most air leaks. Air leaks
can be caused by poor sealing, improper body compo-
nent alignment, body seam porosity, or missing plugs
in the engine compartment or door hinge pillar areas.
All body sealing points should be air tight in normal
driving conditions. Moving sealing surfaces will not
always seal air tight under all conditions. At times,
side glass, door, or convertible top seals will allow wind
noise to be noticed in the passenger compartment
during high cross-winds. Over compensating on door,
glass, or top adjustments to stop wind noise that occurs
under severe conditions, can cause premature seal
wear and excessive closing or latching effort. After a repair procedure has been performed, test vehicle to
verify leak has stopped before returning vehicle to use. Wind noise can also be caused by improperly fitted
exterior mouldings or body ornamentation. Loose
mouldings can flutter, creating a buzzing or chattering
noise. An open cavity or protruding edge can create
whistling or howling noise. Inspect the exterior of the
vehicle to verify that these conditions do not exist.
VISUAL INSPECTION BEFORE TESTS
Verify that floor and body plugs are in place, body
drains are clear and body components are aligned and
sealed. If component alignment or sealing is necessary,
refer to the appropriate section of this group for proper
procedures.
ROAD TESTING WIND NOISE
(1) Drive the vehicle to verify the general location of
the wind noise. (2) Apply 50 mm (2 in.) masking tape in 150 mm (6
in.) lengths along weatherstrips, weld seams or moul-
dings. After each length is applied drive vehicle. If
noise goes away after a piece of tape is applied, remove
tape, locate and repair defect.
POSSIBLE CAUSE OF WIND NOISE
² Mouldings standing away from body surface can
catch wind and whistle.
² Gaps in sealed areas behind overhanging body
flanges can cause wind rushing sounds.
² Misaligned movable components.
² Missing or improperly installed plugs in pillars.
² Weld burn through holes.
