CHECKING
FLUID LEVEL
(1) Position vehicle
on
level surface. This
is ex
tremely important
for
accurate check.
(2)
Apply parking brakes
and run
engine
at
curb
idle speed.
(3)
Shift transmission momentarily into
all
gear
ranges. Then shift back
to
Neutral.
(4)
Clean
top of
filler tube
and
dipstick
(to
avoid
dirt entry)
and
check fluid level. Correct level
is as
follows:
(5)
Be
sure fluid
is at
normal operating tempera
ture (180°F). Correct level
is
between "Maximum Level
Hot"
and
"Add"
marks (crosshatched area)
on
dipstick. (6)
If
fluid level
is
low,
add
only enough fluid
to
correct level.
CAUTION:
Do not
overfill
the
transmission. Overfilling
will
force fluid
out
the
pump vent which
can
be
mistaken
for
a
pump seal leak. Overfilling
will
also
cause
fluid aeration
and foaming
when
the
excess
fluid
is
picked
up
and
churned
by
the
gear train. Aeration
will
reduce fluid
life
significantly.
FLUID
AND
FILTER
CHANGE
Normal Change
Interval
The fluid
and
filter should
be
changed
(and the
bands adjusted)
at
recommended maintenance inter
vals.
Or
whenever
the
transmission
has
been disassembled
for
any
reason.
Recommended Fluid
The recommended
(and
preferred) fluid
for
Chrysler automatic transmissions
is
Mopar
ATF
Plus,
type
7176.

Mopar Dexron
II
only when

Severe Usage Change
Interval
Under severe usage,
the
fluid
and
filter should
be
changed
and the
bands adjusted
at
12,000 mile (19,000
km)
intervals.
Severe usage
is
defined
as:
• More than half
of
vehicle operation occurs
in
heavy city traffic during
hot
weather
at
ambient
temperatures above
90°
F.
• Vehicle
is
used
for
Taxi, Police, Limousine,
or
sim
ilar commercial operations.

drained, refill
the
trans
mission with Mopar
ATF

7176
fluid.
Mo
par Dexron

is
not
readily available.
FLUID
AND
FILTER
REPLACEMENT
PROCEDURE
(1) Raise vehicle, remove
oil pan
and
drain fluid.
(2) Remove filter screws
and
remove filter.
(3) Position
new
filter
on
valve body
and
install fil
ter screws finger tight. (4) Tighten filter screws
to 4
N*m (35
in.
lbs.)
with
torque wrench.
(5) Position
new
gasket
on oil pan
and
install
pan
on transmission. Tighten
pan
bolts
to 17
N»m
(150
in.
lbs.)
torque. (6) Lower vehicle
and
refill transmission with rec
ommended fluid.
GEARSHIFT LINKAGE ADJUSTMENT
Check linkage adjustment
by
starting
the
engine
in Park
and
Neutral. Adjustment
is
OK
if
the
engine starts only
in
park
and Neutral. Adjustment
is
incorrect
if
the
engine starts
in one
but
not
both positions. If
the
engine starts
in
any
position other than Park
or Neutral,
or if
the
engine will
not
start
at
all,
the
park/neutral position switch
may
be
faulty.
