SERVICE PROCEDURES

FLUID LEVEL CHECK

Transmission fluid level should be checked monthly
under normal operation. If the vehicle is used for
trailer towing or similar heavy load hauling, check
fluid level and condition weekly. Fluid level is
checked with the engine running at curb idle speed,
the transmission in NEUTRAL and the transmission
fluid at normal operating temperature.
FLUID LEVEL CHECK PROCEDURE
(1) Transmission fluid must be at normal operat-
ing temperature for accurate fluid level check. Drive
vehicle if necessary to bring fluid temperature up to
normal hot operating temperature of 82°C (180°F).
(2) Position vehicle on level surface.
(3) Start and run engine at curb idle speed.
(4) Apply parking brakes.
(5) Shift transmission momentarily into all gear
ranges. Then shift transmission back to Neutral.
(6) Clean top of filler tube and dipstick to keep
dirt from entering tube.
(7) Remove dipstick (Fig. 64) and check fluid level
as follows:
(a) Correct acceptable level is in crosshatch area.
(b) Correct maximum level is to MAX arrow
mark.
(c) Incorrect level is at or below MIN line.
(d) If fluid is low, add only enough Mopar ATF
Plus 3 to restore correct level. Do not overfill.
CAUTION: Do not overfill the transmission. Overfill-
ing may cause leakage out the pump vent which
can be mistaken for a pump seal leak. Overfilling
will also cause fluid aeration and foaming as the
excess fluid is picked up and churned by the gear
train. This will significantly reduce fluid life.

intervals. 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) Remove the transmission/skip plate as neces-
sary to access the transmission oil pan.
(3) Place a large diameter shallow drain pan
beneath the transmission pan.
(4) Remove bolts holding front and sides of pan to
transmission (Fig. 65).
(5) Loosen bolts holding rear of pan to transmis-
sion.
(6) Slowly separate front of pan away from trans-
mission allowing the fluid to drain into drain pan.
(7) Hold up pan and remove remaining bolts hold-
ing pan to transmission.
(8) While holding pan level, lower pan away from
transmission.
(9) Pour remaining fluid in pan into drain pan.
(10) Remove screws holding filter to valve body
(Fig. 66).
(11) Separate filter from valve body and pour fluid
in filter into drain pan.
(12) Dispose used trans fluid and filter properly.

INSPECTION
Inspect bottom of pan and magnet for excessive
amounts of metal or fiber contamination. A light
coating of clutch or band material on the bottom of
the pan does not indicate a problem unless accompa-
nied by slipping condition or shift lag. If fluid and
pan are contaminated with excessive amounts or
debris, refer to the diagnosis section of this group.
Check the adjustment of the front and rear bands,
adjust if necessary. Refer to Adjustment section of
this group for proper procedure.
