Automatic Transmission Fluid
When to Check and Change
A good time to check your automatic transmission fluid
level is when the engine oil
is changed.
Change both the fluid and filter every
50,000 miles
(83 000 km) if the vehicle is mainly driven under one or
more
of these conditions:
3. Pull out the filter.
0 In heavy city traffic where the outside temperature
regularly reaches
90°F (32°C) or higher.
0 In hilly or mountainous terrain.
When doing frequent trailer towing.
0 Uses such as found in taxi, police or delivery service.
If you do not use your vehicle under any of these
conditions, the fluid and filter do not require changing.
See “Scheduled Maintenance Services”
in the Index.

How to Check
Because this operation can be a little difficult, you
may choose to have this done at your Geo 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.
I 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 (32°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 (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 (IOOC), 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 used
only as a reference. Let the engine run at idle for five
minutes if outside temperatures are
50°F (10°C) 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.

Park your vehicle on a level place. Keep the
engine running.
With the parking brake applied, place the shift lever
in
PARK (P).
With your foot on the brake pedal, move the shift
lever through each gear range, pausing for about
three seconds in each range. Then, position the shift
lever in
PARK (P).
Let the engine run at idle for three minutes or more. Then, without shutting
off the engine, follow these steps:
1. Pull
out the dipstick and wipe it with a clean rag or

then pull it back out again.

3. Check both sides of the dipstick, and read the lower
level. The fluid level must be
in the COLD area for a
cold check or
in the HOT area or cross-hatched area
for a hot check.
4. If the fluid level is in the acceptable range, push the
dipstick back in all the way.
How to Add Fluid
Refer to the Maintenance Schedule to determine what
kind
of transmission fluid to use. See “Recommended
Fluids and Lubricants” in the Index. Add
fluid only after checking the transmission fluid
HOT. (A COLD check
is used only as a reference.) If
the fluid level is low, add only enough of the proper
fluid to bring the level up to the HOT area for a hot
check.
It doesn’t take much fluid, generally less than
one pint
(0.5 L). Don ’I ove$iZZ.
NOTICE:
We recommend you use only fluid labeled
DEXRON@-111, because fluid with that label is
made especially for your automatic transmission.
Damage caused by fluid other than DEXRON-I11
is not covered by your new vehicle warranty.

a level place and the transmission is
cool enough for you
to rest your fingers on the
transmission case. Then, follow these steps:
1. Remove the filler plug.
2. Check that the lubricant
level is up to the bottom of
the filler plug hole.
3. If the fluid level is good, install the plug and be sure
it is fully seated. If the fluid level is low, add more
fluid
as described in the next steps.

Maintenance Schedule
Short Trip/City Definition
Follow the Short Trip/City Maintenance Schedule if any
one
of these conditions is true for your vehicle:
Most trips are less than 5 to 10 miles (8 to 16 km).
This is particularly important when outside
temperatures are below freezing.
Most trips include extensive idling (such as frequent
driving in stop-and-go traffic).
You frequently tow a trailer or use a carrier on top of
your vehicle.
If the vehicle is used for delivery service, police, taxi
or other commercial application.
One of the reasons you should follow this schedule if
you operate your vehicle under any of these conditions
is that these conditions
cause engine oil to breuk
down sooneE
