How
to
Check
Because this operation can be a little difficult, you
may choose to have this done at your GM dealer
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°F (320C).
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
(82°C
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.
