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.

material from gasket surface of transmission case
and the gasket flange around the pan.

TRANSMISSION FILL PROCEDURE

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
Plus 3 to transmission:
(a) If only fluid and filter were changed, add 3
pints (1-1/2 quarts) of ATF Plus 3 to transmis-
sion.
(b) If transmission was completely overhauled,
torque converter was replaced or drained, and
cooler was flushed, add 12 pints (6 quarts) of ATF
Plus 3 to transmission.
(3) Apply parking brakes.
(4) Start and run engine at normal curb idle
speed.
(5) Apply service
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.
