2002 CHRYSLER CARAVAN washer fluid

STATOR
The stator assembly (Fig. 330) is mounted on a sta-
tionary shaft which is an integral part of the oil
pump. The stator is located between the impeller and
turbine within the torque converter case (Fig. 331).
The stator contains an over-running clutch, which
allows the stator to rotate only in a clockwise direc-
tion. When the stator is locked against the over-run-
ning clutch, the torque multiplication feature of the
torque converter is operational.
TORQUE CONVERTER CLUTCH (TCC)
The TCC (Fig. 332) was installed to improve the
efficiency of the torque converter that is lost to the
slippage of the fluid coupling. Although the fluid cou-
pling provides smooth, shock±free power transfer, it
is natural for all fluid couplings to slip. If the impel-
ler and turbine were mechanically locked together, a
zero slippage condition could be obtained. A hydraulic
piston was added to the turbine, and a friction mate-
rial was added to the inside of the front cover to pro-
vide this mechanical lock-up.

ADJUSTMENT - DIFFERENTIAL SIDE GEAR
END PLAY
Measure side gear end play: Insert feeler gauges
180É apart between differential side gear and thrust
washer as shown in (Fig. 124). Measurement taken
here applies to both sides. Side gear end play should
be between 0.025-0.152 mm (0.001-0.006 in.). If clear-
ance is greater than 0.152 mm (0.006 in.), install a
thicker thrust washer (both sides). If clearance is less
than 0.025 mm (0.001), install a thinner thrust
washer (both sides). Refer to (Fig. 125) for available
side gear shim thicknesses.
If end play measurement indicates a thrust washer
change is necessary, the differential must be disas-
sembled. (Refer to 21 - TRANSMISSION/TRANS-
AXLE/MANUAL/DIFFERENTIAL - DISASSEMBLY)

STANDARD PROCEDURE
STANDARD PROCEDURE - FLUID LEVEL
CHECK
NOTE: For proper fluid level check intervals, (Refer
to LUBRICATION & MAINTENANCE/MAINTENANCE
SCHEDULES - DESCRIPTION)
The fluid required in this transaxle is Mopart
ATF+4 (Automatic Transmission FluidÐType 9602).
Use of substitute fluids may result in improper
transaxle operation and/or failure.
(1) Raise vehicle on hoist.(2) Remove transaxle fill plug (Fig. 126).
(3) Inspect fluid level. Fluid should be within 1/8º
below fill hole. Add MopartATF+4 (Automatic Trans-
mission FluidÐType 9602) as neccessary.
(4) Install fill plug, ensuring it is properly seated.
(5) Lower vehicle.

DESCRIPTION
The EGR system consists of:
²EGR tube (connects a passage in the intake
manifold to the exhaust port in the cylinder head)
²EGR valve
²Electronic EGR Transducer
²Connecting hoses
OPERATION
Refer to Monitored Systems - EGR Monitor in this
group for more information.
The engines use Exhaust Gas Recirculation (EGR)
systems. The EGR system reduces oxides of nitrogen
(NOx) in engine exhaust and helps prevent detona-
tion (engine knock). Under normal operating condi-
tions, engine cylinder temperature can reach more
than 3000ÉF. Formation of NOx increases proportion-
ally with combustion temperature. To reduce the
emission of these oxides, the cylinder temperature
must be lowered. The system allows a predetermined
amount of hot exhaust gas to recirculate and dilute
