1. Start engine and apply parking brake.
2. Shift the transmission into DRIVE for approximately 2 seconds.
3. Shift the transmission into REVERSE for approximately 2 seconds.
4. Shift the transmission into PARK.
5. Hook up DRB
scan tool and select engine.
6. Select sensors.
7. Read the transmission temperature value.
8. Compare the fluid temperature value with the chart.
9. Adjust transmission fluid level shown on the dipstick according to the chart.
NOTE: After adding any fluid to the transmission, wait a minimum of 2 minutes for the oil to fully drain from
the fill tube into the transmission before rechecking the fluid level.
10. Check transmission for leaks.
FLUID AND FILTER REPLACEMENT
For proper service intervals (Refer to LUBRICATION & MAINTENANCE/MAINTENANCE SCHEDULES - DESCRIP-
TION). The service fluid fill after a filter change is approximately 3.8 liters (4.0 quarts).

REMOVAL
1. Hoist and support vehicle on safety stands.
2. Place a large diameter shallow drain pan beneath
the transmission pan (3).
3. Remove bolts holding front and sides of pan to
transmission (1).
4. Loosen bolts holding rear of pan to transmission.
5. Slowly separate front of pan and reusable gasket
(2) away from transmission allowing the fluid to
drain into drain pan.
6. Hold up pan and remove remaining bolt holding
pan to transmission.
7. While holding pan level, lower pan and gasket
away from transmission.
8. Pour remaining fluid in pan into drain pan.
9. Remove screws holding filter (2) to valve body.
10. Separate filter from valve body and pour fluid in
filter into drain pan.
11. Dispose of used trans fluid and filter properly.
INSTALLATION
1. Position a new transmission oil filter (2) onto the
valve body.
2. Install the screws to hold the filter to the valve
body. Tighten the screws to 4 Nꞏm (35 in.lbs.).

3. Clean the gasket surfaces of the transmission oil
pan (3) and transmission pan rail.
NOTE: The transmission pan oil gasket (2) is reus-
able. Inspect the sealing surfaces of the gasket. If
the sealing ribs on both surfaces appear to be in
good condition, clean the gasket of any foreign
material and reinstall.
4. Position the oil pan gasket (2) onto the oil pan (3).
5. Position the oil pan and gasket onto the transmis-
sion and install several bolts to hold the pan and
gasket to the transmission.
6. Install the remainder of the oil pan bolts. Tighten
the bolts to 13.6 Nꞏm (125 in.lbs.).
7. Lower vehicle and fill transmission. (Refer to 21 -
TRANSMISSION/AUTOMATIC/FLUID - STANDARD PROCEDURE)
TRANSMISSION FILL
To avoid overfilling transmission after a fluid change or overhaul, perform the following procedure:
1. Remove dipstick and insert clean funnel in transmission fill tube.
2. Add following initial quantity of Mopar
ATF+4totransmission:
a. If only fluid and filter were changed, add3 pints (1-1/2 quarts)of ATF +4 to transmission.
b. If transmission was completely overhauled, torque converter was replaced or drained, and cooler was
flushed, add12 pints (6 quarts)of ATF +4 to transmission.
3. Apply parking brakes.
4. Start and run engine at normal curb idle speed.
5. Apply service brakes, shift transmission through all gear ranges then back to NEUTRAL, set parking brake, and
leave engine running at curb idle speed.
6. Remove funnel, insert dipstick andcheck fluid level. If level is low,add fluid to bring level to MIN mark on
dipstick.Check to see if the oil level is equal on both sides of the dipstick. If one side is noticably higher than
the other, the dipstick has picked up some oil from the dipstick tube. Allowthe oil to drain down the dipstick tube
and re-check.
7. Drive vehicle until transmission fluid is at normal operating temperature.
8. With the engine running at curb idle speed, the gear selector in NEUTRAL,and the parking brake applied, check
the transmission fluid level.
CAUTION: Do not overfill transmission, fluid foaming and shifting problems can result.
9. Add fluid to bring level up to MAX arrow mark.
When fluid level is correct, shut engine off, release park brake, remove funnel, and install dipstick in fill tube.

CLUTCH-FRONT
DESCRIPTION
The front clutch assembly is composed of the front clutch retainer (11), pressure plate, clutch plates (4), clutch discs
(7), clutch piston (2), clutch piston return spring (9), clutch piston spring retainer (3), and snap-rings (5, 8). The front
clutch is the forward-most component in the transmission geartrain and isdirectly behind the oil pump and is con-
sidered a driving component.
OPERATION
To apply the clutch, pressure is applied between the clutch retainer and piston. The fluid pressure is provided by the
oil pump, transferred through the control valves and passageways, and enters the clutch through the hub of the
reaction shaft support. With pressure applied between the clutch retainer and piston, the piston moves away from
the clutch retainer and compresses the clutch pack. This action applies the clutch pack, allowing torque to flow
through the input shaft into the driving discs, and into the clutch plates and pressure plate that are lugged to the
clutch retainer. The waved snap-ring is used to cushion the application ofthe clutch pack.
When pressure is released from the piston, the spring returns the piston toits fully released position and disen-
gages the clutch. The release spring also helps to cushion the applicationof the clutch assembly. When the clutch
is in the process of being released by the release spring, fluid flows through a vent and one-way ball-check-valve
located in the clutch retainer. The check-valve is needed to eliminate thepossibility of plate drag caused by cen-
trifugal force acting on the residual fluid trapped in the clutch piston retainer.

PUMP-OIL
DESCRIPTION
The oil pump is located in the pump housing inside the bell housing of the transmission case. The oil pump consists
of an inner gear (9), outer gear (10), a body (3), and a reaction shaft support(5).
OPERATION
As the torque converter rotates, the converter hub rotates the inner and outer gears. As the gears rotate, the clear-
ance between the gear teeth increases in the crescent area, and creates a suction at the inlet side of the pump.
This suction draws fluid through the pump inlet from the oil pan. As the clearance between the gear teeth in the
crescent area decreases, it forces pressurized fluid into the pump outletand to the valve body.

fluid before installation.
3. If reaction shaft seal rings (6) are being replaced, install new seal rings on support hub. Lubricate seal rings with
transmission fluid or petroleum jelly after installation. Squeeze each ring until ring ends are securely hooked
together.
CAUTION: The reaction shaft support seal rings will break if overspread, or twisted. If new rings are being
installed, spread them only enough forinstallation. Also be very sure thering ends are securely hooked
together after installation. Otherwise, the rings will either prevent pump installation, or break during instal-
lation.

CLUTCH-OVERDRIVE
DESCRIPTION
The overdrive clutch is composed of the pressure plate (2), clutch plates,holding discs, overdrive piston retainer,
piston, piston spacer, and snap-rings. The overdrive clutch is the forwardmost component in the transmission over-
drive unit and is considered a holding component. The overdrive piston retainer, piston, and piston spacer are
located on the rear of the main transmission case.
NOTE: The number of discs and plates may vary with each engine and vehicle combination.
OPERATION
To apply the clutch, pressure is applied between the piston retainer and piston. The fluid pressure is provided by the
oil pump, transferred through the control valves and passageways, and enters the clutch through passages at the
lower rear portion of the valve body area. With pressure applied between the piston retainer and piston, the piston
moves away from the piston retainer and compresses the clutch pack. This action applies the clutch pack, allowing
torque to flow through the intermediate shaft into the overdrive planetary gear set. The overdrive clutch discs are
attached to the overdrive clutch hub while the overdrive clutch plates, reaction plate, and pressure plate are lugged
to the overdrive housing. This allows the intermediate shaft to transfer the engine torque to the planetary gear and
overrunning clutch. This drives the planetary gear inside the annulus, which is attached to the overdrive clutch drum
and output shaft, creating the desired gear ratio. The waved snap-ring is used to cushion the application of the
clutch pack for the 5 disc version of the overdrive clutch. The 6 disc overdrive clutch does not use a waved snap-
ring.

REMOVAL
1. Shift transmission into PARK.
2. Raise vehicle.
3. Remove transfer case, if equipped.
4. Mark propeller shaft universal joint(s) and axle pinion yoke, or the companion flange and flange yoke, for align-
ment reference at installation, if necessary.
5. Disconnect and remove the rear propeller shaft, if necessary. (Refer to3 - DIFFERENTIAL & DRIVELINE/PRO-
PELLER SHAFT/PROPELLER SHAFT - REMOVAL)
6. Remove transmission oil pan, remove gasket, drain oil and reinstall pan.
7. If overdrive unit had malfunctioned, or if fluid is contaminated, remove entire transmission. If diagnosis indicated
overdrive problems only, remove just the overdrive unit.
8. Support transmission with transmission jack.
9. Remove bolts (2) attaching overdrive unit (1) to
transmission.
CAUTION: Support the overdrive unit with a jack
before moving it rearward. This is necessary to
prevent damaging the intermediate shaft. Do not
allow the shaft to support the entire weight of the
overdrive unit.
10. Carefully work overdrive unit off intermediate
shaft. Do not tilt unit during removal. Keep it as
level as possible.
11. If overdrive unit does not require service, immedi-
ately insert Alignment Tool 6227-2 in splines of
planetary gear and overrunning clutch to prevent
splines from rotating out of alignment. If misalign-
ment occurs, overdrive unit will have to be disas-
sembled in order to realign splines.
12. Remove and retain overdrive piston thrust bearing. Bearing may remainon piston or in clutch hub during
removal.
13. Position drain pan on workbench.
14. Place overdrive unit over drain pan. Tilt unit to drain residual fluid from case.
15. Examine fluid for clutch material or metal fragments. If fluid contains these items, overhaul will be necessary.
16. If overdrive unit does not require any service, leave alignment tool inposition. Tool will prevent accidental mis-
alignment of planetary gear and overrunning clutch splines.
