AUTOMATIC
TRANSMISSION
FLUID
RECOMMENDATION
Use
only automatic transmission fluid
labeled with the mark
DEXRON® II. You
can
buy these fluids from your Oldsmobile
dealer or other
service
outlets.
Check the fluid
level.
at each engine oil
change period. Overfilling
can
cause
foaming and loss of fluid. Transmission
damage
can
result. Low fluid
level
can
cause slipping or loss of drive.
Automatic
transmissions are often
overfilled because the fluid
level
is checked
when the fluid
is cold.
When
cold, the
dipstick
shows
that fluid should be added.
However, the
low
reading
is
normal; the
level
will
rise
as the fluid gets warm. The
fluid
level
will
increase more than 3/4 inch
(19 mm)
as
fluid warms up from 60°
to
180°F (16°
to
82°C).
Check
the transmission fluid
level
with the
engine running, the shift
lever
in
"PARK"
and the car level.
NOTICE:
If
the
CIlr
has just been driven for a
long time
at
high speed or in city traffic
in
hot
weather, or
if
the
car
has been pulling a
trailer, the correct fluid level
CIlnnot
be
read.
Wait
until the fluid has cooled down (about
30
minutes).
Remove the dipstick. Carefully touch the
wet end
of
the dipstick
to
find out
if
the
fluid
is
cool, warm or hot.
Wipe
it clean
and replace until cap seats. Pull out the
dipstick and read.

OIL
l.EVEL GAGE
COOL
•
If
it felt cool, about room temperature,
the
level
should be 1/8
to
3/8 inch (3
to
10 mm) below the "ADD" mark. The
dipstick has two dimples below the
"ADD" mark
to
show
this range.
•
If
it felt warm the level should be
close
to
the "ADD" mark (either above or
below).
• If it was too hot
to
hold, the level
should be at the
"FULL" mark.
NOTICE:
DO
NOT
OVERFILL.
It
takes
only one pint
(0.5 litre) to
raise
level from
"ADD" to "FULL" with a
hot
transmission.
