(8) Start engine and allow to idle for at least one
minute. Then, with parking and service brakes
applied, move selector lever momentarily to each
position, ending in the park or neutral position.
(9) Check the transaxle fluid level and add an
appropriate amount to bring the transaxle fluid level
to 3mm (1/8 in.) below the ªADDº mark on the dip-
stick (Fig. 168).
(10) Recheck the fluid level after the transaxle has
reached normal operating temperature (180ÉF.).
(Refer to 21 - TRANSMISSION/TRANSAXLE/AUTO-
MATIC - 31TH/FLUID - STANDARD PROCEDURE)(11) To prevent dirt from entering transaxle, make
certain that dipstick is fully seated into the dipstick
opening.
DIPSTICK TUBE FLUID SUCTION METHOD
(ALTERNATIVE)
(1) When performing the fluid suction method,
make sure the transaxle is at full operating temper-
ature.
(2) To perform the dipstick tube fluid suction
method, use a suitable fluid suction device (VaculaŸ
or equivalent).
(3) Insert the fluid suction line into the dipstick
tube.
NOTE: Verify that the suction line is inserted to the
lowest point of the transaxle oil pan. This will
ensure complete evacuation of the fluid in the pan.
(4) Follow the manufacturers recommended proce-
dure and evacuate the fluid from the transaxle.
(5) Remove the suction line from the dipstick tube.
(6) Pour four quarts of MopartATF+4 (Automatic
Transmission FluidÐType 9602) through the dipstick
opening.
(7) Start engine and allow to idle for at least one
minute. Then, with parking and service brakes
applied, move selector lever momentarily to each
position, ending in the park or neutral position.

(6) Adjust transmission fluid level shown on the
indicator according to the chart.
(7) Check transmission for leaks.
Low fluid level can cause a variety of conditions
because it allows the pump to take in air along with
the fluid. As in any hydraulic system, air bubbles
make the fluid spongy, therefore, pressures will be
low and build up slowly.
Improper filling can also raise the fluid level too
high. When the transaxle has too much fluid, the
gears churn up foam and cause the same conditions
which occur with a low fluid level.
In either case, air bubbles can cause overheating
and/or fluid oxidation, and varnishing. This can
interfere with normal valve, clutch, and accumulator
operation. Foaming can also result in fluid escaping
from the transaxle vent where it may be mistaken
for a leak.
FLUID CONDITION
Along with fluid level, it is important to check the
condition of the fluid. When the fluid smells burned,
and is contaminated with metal or friction material
particles, a complete transaxle recondition is proba-
bly required. Be sure to examine the fluid on the dip-
stick closely. If there is any doubt about its condition,
drain out a sample for a double check.
MopartATF+4 (Automatic Transmission Fluid-
Type 9602) when new is red in color. The ATF is dyed
red so it can be identified from other fluids used in
the vehicle such as engine oil or antifreeze. The red
color is not permanent and is not an indicator of fluid
condition. As the vehicle is driven, the ATF will begin
to look darker in color and may eventually become
brown.This is normal.ATF+4 also has a unique
odor that may change with age. Consequently,odor
and color cannot be used to indicate the fluid
condition or the need for a fluid change.
After the fluid has been checked, seat the dipstick
fully to seal out water and dirt.
STANDARD PROCEDURE - FLUID AND FILTER
SERVICE
NOTE: Refer to the maintenance schedules in
LUBRICATION and MAINTENANCE, or the vehicle
owner's manual, for the recommended maintenance
(fluid/filter change) intervals for this transaxle.
NOTE: Only fluids of the type labeled MoparTATF+4
(Automatic Transmission Fluid) Type 9602 should
be used. A filter change should be made at the time
of the transmission oil change. The magnet (on the
inside of the oil pan) should also be cleaned with a
clean, dry cloth.NOTE: If the transaxle is disassembled for any rea-
son, the fluid and filter should be changed.
FLUID/FILTER SERVICE (RECOMMENDED)
(1) Raise vehicle on a hoist. Refer to LUBRICA-
TION and MAINTENANCE for proper procedures.
Place a drain container with a large opening, under
transaxle oil pan.
(2) Loosen pan bolts and tap the pan at one corner
to break it loose allowing fluid to drain, then remove
the oil pan.
(3) Install a new filter and o-ring on bottom of the
valve body (Fig. 212).
(4) Clean the oil pan and magnet. Reinstall pan
using new Mopar Silicone Adhesive sealant. Tighten
oil pan bolts to 19 N´m (165 in. lbs.).
(5) Pour four quarts of MopartATF+4 (Automatic
Transmission Fluid) Type 9602 through the dipstick
opening.
(6) Start engine and allow to idle for at least one
minute. Then, with parking and service brakes
applied, move selector lever momentarily to each
position, ending in the park or neutral position.

Inspect for the following:
²Verify correct (OEM) wheel and tire, as well as
correct wheel weights. Aluminum wheels require
unique wheel weights. They are designed to fit the
contour of the wheel (Fig. 1).
²Inspect tires and wheels for damage, mud pack-
ing and unusual wear; correct as necessary.
²Check and adjust tire air pressure to the pres-
sure listed on the label attached to the rear face of
the driver's door.
ROAD TEST
Road test vehicle on a smooth road for a least five
miles to warm tires (remove any flat spots). Lightly
place hands on steering wheel at the 10:00 and 2:00
positions while slowly sweeping up and down from 90 to
110 km/h (55 to 70 mph) where legal speed limits allow.
Observe the steering wheel for:
²Visual Nibble (oscillation: clockwise/counter-
clockwise, usually due to tire imbalance)
²Visual Buzziness (high frequency, rapid vibra-
tion up and down)
To rule out vibrations due to brakes or powertrain:
²Lightly apply brakes at speed; if vibration occurs
or is enhanced, vibration is likely due to causes other
than tire and wheel assemblies.
²
Shift transmission into neutral while vibration is
occurring; if vibration is eliminated, vibration is likely
due to causes other than tire and wheel assemblies.
For brake vibrations, (Refer to 5 - BRAKES -
BASE/HYDRAULIC/MECHANICAL/ROTORS -
DIAGNOSIS AND TESTING).
For powertrain vibrations, (Refer to 3 - DIFFEREN-
TIAL & DRIVELINE - DIAGNOSIS AND TESTING).
For tire and wheel assembly vibrations, continue
with this diagnosis and testing procedure.
TIRE AND WHEEL BALANCE
(1) Balance the tire and wheel assemblies as nec-
essary following the wheel balancer manufacturer's
instructions and using the information listed in Stan-
dard Procedure - Tire And Wheel Balance. (Refer to
22 - TIRES/WHEELS - STANDARD PROCEDURE)
(2) Road test the vehicle for at least 5 miles, fol-
lowing the format described in Road Test.
(3) If the vibration persists, continue with this
diagnosis and testing procedure.
TIRE AND WHEEL RUNOUT/MATCH MOUNTING
(1)System Radial Runout.This on-the-vehicle
system check will measure the radial runout includ-
ing the hub, wheel and tire.
(a) Raise vehicle so tires clear floor. (Refer to
LUBRICATION & MAINTENANCE/HOISTING -
STANDARD PROCEDURE)
(b) Apply masking tape around the circumfer-
ence of the tire in the locations to be measured
(Fig. 2). Do not overlap the tape.
(c) Check system runout using Dial Indicator
Set, Special Tool C-3339A with 25-W wheel, or
equivalent. Place the end of the indicator against
each taped area (one at a time) (Fig. 2) and rotate
the tire and wheel. System radial runout should
not exceed 0.76 mm (0.030 inch) with no tread
ªdipsº or ªsteps.º Tread ªdipsº and ªstepsº can be
identified by spikes of the dial indicator gauge.
²Tread9dips9; Rapid decrease then increase in
dial indicator reading over 101.6 mm (4.0 inch) of
tread circumference.
²Tread9steps9; Rapid decrease or increase in dial
indicator reading over 101.6 mm (4.0 inch) of tread
circumference.
(d) If system runout is excessive, re-index the
tire and wheel assembly on the hub. Remove
assembly from vehicle and install it back on the
hub two studs over from original mounting posi-
tion. If re-indexing the tire and wheel assembly
corrects or reduces system runout, check hub
runout and repair as necessary (Refer to 5 -
BRAKES - BASE/HYDRAULIC/MECHANICAL/
ROTORS - DIAGNOSIS AND TESTING).
(e) If system runout is still excessive, continue
with this diagnosis and testing procedure.
(2)Tire and Wheel Assembly Radial Runout.
This radial runout check is performed with the tire
and wheel assembly off the vehicle.
(a) Remove tire and wheel assembly from vehicle
and install it on a suitable wheel balancer.
(b) Check system runout using Dial Indicator
Set, Special Tool C-3339A with 25-W wheel, or
equivalent. Place the end of the indicator against
each taped area (one at a time) (Fig. 2) and rotate
the tire and wheel. Radial runout should not
