Check
Because this operation can be a little difficult, you may
choose to have this done at your Pontiac dealership
Service Department.
If
you do it yourself, be sure to follow all the instructions
here, or you could get a false reading
on
the dipstick.
NOTICE:
Too
much
or
too little fluid can damage your
transmission.
Too
much can mean that some
of
the fluid could come out and fall
on
hot engine
parts
or
exhaust
system
parts, starting
a
fire. Be
sure to get an accurate reading if you check your
transmission fluid.
Wait at least
30
minutes before checking the
transmission fluid level if you have been driving:
When outside temperatures are above
90
OF
(32
O
C).
At high speed for quite a while.
In
heavy
traffic
--
especially in hot weather.
While pulling a trailer.
To
get the right reading, the fluid should be at
normal operating temperature, which
is
180°F
to
200°F
(82OC
to
93°C).
Checking Transmission Fluid Hot
Get the vehicle warmed up by driving
about
15
miles
(24
km) when outside temperatures are above
50°F
(10°C).
If
it's colder than
50°F
(lO"C),
drive
the
vehicle in
DRIVE
(D)
until
the
engine temperature gage
moves and then remains steady for
10
minutes. Then
follow the hot check procedures.
Checking Transmission Fluid Cold
A
cold check
is
made after the vehicle has been sitting
for
eight hours
or
more with the engine
off
and
is
d
only as a reference. Let the engine run at idle for five
minutes if outside temperatures are
50°F
(10OC) or
more. If it's colder than
50°F
(lO"C),
you may have to
idle the engine longer. Should the fluid level be low
during a cold check,
you
must
perform a hot check
before adding fluid. This will give you a more accurate
reading
of
the fluid level.
