1998 PONTIAC FIREBIRD automatic transmission

When you open the hood of the 5.7L V8 engine you’ll see:
A. Engine Coolant Reservoir
B. Battery
C. Engine Oil Dipstick
D. Engine Oil Fill Cap
E. Windshield Washer Reservoir F.
Engine Cooling Fan
G. Automatic Transmission
Dipstick
(If Equipped)
H. Air Filter
I. Power Steering Reservoir
J. Brake Fluid Reservoir
K. Clutch Fluid Reservoir
(If Equipped)

If you have the 5.7L V8 engine (with the WS6 option),
your air cleaner will be located over the radiator near the
front of the engine.
To remove the filter, remove the screws (located on the
rear edge of the air cleaner), lift the
air cleaner and
remove the filter.
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
15,000 miles
(25 000 km) if the vehicle is mainly driven under one
or more
of these conditions:
0 In heavy city traffic where the outside temperature
regularly reaches
90°F (32°C) or higher.
In hilly or mountainous terrain.
Uses such as high performance operation.
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, change the fluid and filter every
50,000 miles (83 000 km).
See “Scheduled Maintenance Services” in the Index.
6-20

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
while it is 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’t ove@ZZ.
I 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.
After adding fluid, recheck the fluid level as
described under “How to Check.”
When the correct fluid level is obtained, push the
dipstick back in all the
way.
Manual Transmission Fluid
When to Check
A good time to have it checked is when the engine
oil is changed. However, the fluid in your manual
transmission doesn’t require changing.

you’re not sure, ask your Pontiac dealer.

Maintenance Schedule
Short Trip/City Definition
Follow the Short TripKity 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.
0 Most trips include extensive idling (such as frequent
driving in stop-and-go traffic).
0 Most trips are through dusty areas.
0 You frequently tow a trailer or use a carrier on top of
0 If the vehicle is used for delivery service, police, taxi
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 break
down soonez
your vehicle.
