STANDARD PROCEDURE - FLUID AND FILTER
REPLACEMENT
For proper service intervals (Refer to LUBRICA-
TION & MAINTENANCE/MAINTENANCE SCHED-
ULES - DESCRIPTION). The service fluid fill after a
filter change is approximately 3.8 liters (4.0 quarts).
(1) Hoist and support vehicle on safety stands.
(2) Place a large diameter shallow drain pan
beneath the transmission pan.
(3) Remove bolts holding front and sides of pan to
transmission (Fig. 91).
(4) Loosen bolts holding rear of pan to transmis-
sion.
(5) Slowly separate front of pan away from trans-
mission allowing the fluid to drain into drain pan.
(6) Hold up pan and remove remaining bolt hold-
ing pan to transmission.
(7) While holding pan level, lower pan away from
transmission.
(8) Pour remaining fluid in pan into drain pan.
(9) Remove screws holding filter to valve body
(Fig. 92).
(10) Separate filter from valve body and pour fluid
in filter into drain pan.
(11) Dispose of used trans fluid and filter properly.
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 MopartAT F
+4, type 9602, to transmission:(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 and check 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. Allow the
oil to drain down the dipstick tube and re-check.
(7) Drive vehicle until transmission fluid is at nor-
mal 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 foam-
ing 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.

FLUID AND FILTER (Continued)

Improper filling can also raise the fluid level too
high. When the transmssion has too much fluid, the
geartrain churns up foam and cause the same condi-
tions 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 transmission vent where it may be mis-
taken for a leak.
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 transmission recondition is
needed. Be sure to examine the fluid on the dipstick
closely. If there is any doubt about its condition,
drain out a sample for a double check.
After the fluid has been checked, seat the dipstick
fully to seal out water and dirt.
The transmission has a dipstick to check oil level.
It is located on the right side of the engine. Be sure
to wipe all dirt from dipstick handle before removing.
Fluid level is checked with the engine running at
curb idle speed, the transmission in NEUTRAL and
the transmission fluid at normal operating tempera-
ture.The engine should be running at idle
speed for at least one minute, with the vehicle
on level ground.
The transmission fluid level can be checked two
ways.

FRONT CLUTCH
DESCRIPTION
The front clutch assembly (Fig. 87) is composed of
the front clutch retainer, pressure plate, clutch
plates, driving discs, piston, piston return spring,
return spring retainer, and snap-rings. The front
clutch is the forward-most component in the trans-
mission geartrain and is directly behind the oil pump
and is considered a driving component.
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 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 of the clutch pack.
When pressure is released from the piston, the
spring returns the piston to its fully released position
and disengages the clutch. The release spring also
helps to cushion the application of the clutch assem-
bly. 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 elimi-
nate the possibility of plate drag caused by centrifu-
gal force acting on the residual fluid trapped in the
clutch piston retainer.

UNDER HOOD
INSPECTION - HOOD LATCH/SAFETY CATCH
(1) Check operation of hood latch (Fig. 2) and
safety catch (Fig. 3) adjust as required.
NOTE: The safety catch prevents the hood from
going to full open position until it is manually
released. To test the safety catch, unlock the hood
with the interior release, then try to raise the hood
without operating the safety catch.
INSPECTION - FLUID LEVELS
ENGINE OIL
CAUTION: Use only oil that meets the specified
requirements.
NOTE: If oil level is low, inspect for oil leaks.
(1) Check engine oil level. The oil should be in the
safe range or between the minimum and maximum
marks.
²If the oil level is at the minimum mark, add oil
that meets specifications, (Refer to LUBRICATION &
MAINTENANCE/FLUID TYPES - DESCRIPTION).
²The best time to check the oil is about 5 minutes
after a fully warmed-up engine is turned off, or
before starting the engine after it has been off over-
night.²For the most accurate readings, the vehicle
should be on level ground.
²Wipe up any excess oil that may have spilled, or
the customer could mistakenly perceive this as the
result of a leak.
AUTOMATIC TRANSMISSION
CAUTION: Only use fluid that meets the vehicle's
specific requirement.
NOTE: Mopar ATF Plus contains special additives
not found in Mercon and Dexron II fLuids. Use of
fluid other than Mopar Plus (when specified) could
result in an upshift shudder in some applications.
Transmission fluid check procedures are specific to
each vehicle line. Refer to the appropriate service
information for correct procedure.
CLUTCH MASTER CYLINDER
CAUTION: only use brake fluid that meets specified
requirements (DOT 3 and MVSS 116).

side of the reservoir (or above the bottom of the split
ring in the primary filler hole). Be sure both primary
and secondary cavities are full to the maximum level
as indicated.
POWER STEERING RESERVOIR
CAUTION: Only use fluid that meets specified
requirements. Petroleum fluids, such as Mopar
Power Steering Fluid, are specially formulated for
use with power steering hoses and seals.
Check the fluid level; it should be maintained at
the proper level indicated on the dipstick, or as
viewed through the translucent reservoir. If fluid is
required, fill to the proper level. With the engine run-
ning at normal operating temperature, turn the
steering wheel from stop to stop to expel air fromwithin the system Stop the engine, remove the cap,
and recheck the fluid level, making sure that foam-
ing is not present (Fig. 5).
