ACCUMULATOR
DESCRIPTION
The 41te underdrive, overdrive, low/reverse, and
2/4 clutch hydraulic circuits each contain an accumu-
lator. An accumulator typically consists of a piston,
seals, return spring(s), and a cover or plug. The over-
drive and underdrive accumulators are located
within the transaxle case, and are retained by the
valve body (Fig. 168).
The low reverse accumulator (Fig. 169) is also
located within the transaxle case, but the assembly is
retained by a cover and a snap-ring.
The 2/4 accumulator is located in the valve body. It
is retained by a cover and retaining screws (Fig.
170).

OPERATION
The function of an accumulator is to cushion the
application of a frictional clutch element. When pres-
surized fluid is applied to a clutch circuit, the appli-
cation force is dampened by fluid collecting in the
respective accumulator chamber against the piston
and spring(s). The intended result is a smooth, firm
clutch application.
AUTOSTICK SWITCH
DESCRIPTION
Autostick is a driver-interactive transaxle feature
that offers manual gear shifting capability. The control
switch is part of the transaxle gear shift lever as
shown in (Fig. 171). It can only be serviced by replac-
ing the gearshift lever assembly. (Refer to 19 - STEER-
ING/COLUMN/GEAR SHIFT LEVER - REMOVAL)
OPERATION
When the shift lever is moved into the Autostick
position (as indicated by the Shift Lever Position
Indicator in the cluster), the transaxle remains in
whatever gear it was using before Autostick was acti-
vated. The TCM sends a 5 volt signal through the
switch and then monitors the signal for voltage drop.
Each switch state (driver command) results in a spe-
cific voltage reading sensed by the TCM. The TCM
then determines transaxle operation (upshift/down-
shift/OD Lockout) based on their corresponding volt-
age. Refer to the following chart for corresponding
switch states and voltage readings:
Switch State Voltage Reading
Autostick DOWN
depressed0.3V-1.6V
Autostick UP depressed 1.6V-2.8V
Overdrive OFF9Lockout9
depressed2.8V-3.8V
All switches open 3.8V-4.8V
-Voltage values <.3V and >4.8V are considered
INVALID and will result in a DTC

Moving the switch up causes an upshift and moving
the switch down causes a downshift. The instrument
cluster will illuminate the selected gear. The vehicle
can be launched in 1st, 2nd, or 3rd gear while in the
Autostick mode. The speed control is operable in 3rd
and 4th gear Autostick mode. Speed control will be
deactivated if the transaxle is shifted to 2nd gear.
Shifting into OD position cancels the Autostick mode,
and the transaxle resumes the OD shift schedule.
DRIVING CLUTCHES
DESCRIPTION
Three hydraulically applied input clutches are used
to drive planetary components. The underdrive, over-
drive, and reverse clutches are considered input
clutches and are contained within the input clutch
assembly (Fig. 172). The input clutch assembly also
contains:
²Input shaft
²Input hub
²Clutch retainer
²Underdrive piston
²Overdrive/reverse piston
²Overdrive hub
²Underdrive hub
OPERATION
The three input clutches are responsible for driving
different components of the planetary geartrain.
NOTE: Refer to the ªElements In Useº chart in Diag-
nosis and Testing for a collective view of which
clutch elements are applied at each position of the
selector lever.
UNDERDRIVE CLUTCH
The underdrive clutch is hydraulically applied in
first, second, and third (direct) gears by pressurized
fluid against the underdrive piston. When the under-
drive clutch is applied, the underdrive hub drives the
rear sun gear.
OVERDRIVE CLUTCH
The overdrive clutch is hydraulically applied in
third (direct) and overdrive gears by pressurized fluid
against the overdrive/reverse piston. When the over-
drive clutch is applied, the overdrive hub drives the
front planet carrier.
REVERSE CLUTCH
The reverse clutch is hydraulically applied in
reverse gear only by pressurized fluid against the
overdrive/reverse piston. When the reverse clutch is
applied, the front sun gear assembly is driven.
FINAL DRIVE
DISASSEMBLY
NOTE: The differential is serviced as an assembly.
Differential service is limited to bearing cups and
cones. Any other differential component failure
must be remedied by differential assembly and
transfer shaft replacement.

(3) Select sensors.
(4) Read the transmission temperature value.
(5) Compare the fluid temperature value with the
fluid temperature chart (Fig. 210).
(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)
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.

ADJUSTMENT
(1) Park the vehicle on level ground and set the
parking brake.
(2) Place the gearshift lever in gated park (P) and
remove ignition key.
(3) Loosen the cable adjustment screw at the
transaxle manual valve lever (Fig. 223).
(4) Pull the gearshift lever fully forward to the
park detent position.
(5) Release the park brake, then rock the vehicle
to assure it is in park. Reset the park brake.
(6) Tighten the cable adjustment screw to 8 N´m
(70 in. lbs.). Gearshift cable should now be properly
adjusted.
(7) Verify adjustment by using the verification pro-
cedure.
HOLDING CLUTCHES
DESCRIPTION
Two hydraulically applied multi-disc clutches are
used to hold planetary geartrain components station-
ary while the input clutches drive others. The 2/4
and Low/Reverse clutches are considered holding
clutches and are contained at the rear of the trans-
axle case. (Fig. 224).
OPERATION
NOTE: Refer to the ªElements In Useº chart in Diag-
nosis and Testing for a collective view of which
clutch elements are applied at each position of the
selector lever.
2/4 CLUTCH
The 2/4 clutch is hydraulically applied in second
and fourth gears by pressurized fluid against the 2/4
clutch piston. When the 2/4 clutch is applied, the
front sun gear assembly is held or grounded to the
transaxle case.
LOW/REVERSE CLUTCH
The Low/Reverse clutch is hydraulically applied in
park, reverse, neutral, and first gears by pressurized
fluid against the Low/Reverse clutch piston. When
the Low/Reverse clutch is applied, the front planet
carrier/rear annulus assembly is held or grounded to
the transaxle case.
