Automatic Transaxle Fluid
When to Check and Change:
A good time to check your automatic
transaxle fluid level is when the engine
oil is changed. Refer to the Maintenance
Schedule to determine when to change
your fluid. See the
Index under
Scheduled Maintenance Services.
How to Check:
Because this operation can be a little
difficult, you may choose to have this
done at an Oldsmobile 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.

3800 V6: Checking Automatic
Transaxle Fluid
Refer to the Maintenance Schedule to
determine what kind
of transaxle fluid to
use. See the Index under Fluids &
Lubricants.
If the fluid level is low, add only enough
of the proper fluid to bring the level into
the cross-hatched area on the dipstick.
It doesn’t take much fluid, generally less
than a pint (0.5 L). Don’t overfill. We
recommend you use
only fluid labeled
DEXRON@-IIE, because fluids with that
label are made especially for your
automatic transaxle. Damage caused
by
fluid other than DEXRON -DE 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.

/njector 3365 Fuse
(3800 V6 ENGINE ONLY)
This 20-amp fuse is located underhood,
on a bracket just behind the passenger
side headlight.
It is mounted on the face
of the bracket in the position closest to
the passenger side of the vehicle. The
fuse services the injectors, fuel pump,
oil pressure sender and fuel pump
switch.
To access the fuse, pry back the latch
with a screwdriver,
then pull down on
the base of the unit. If you need to
replace the fuse, be sure to use a
20-amp fuse.
Push the base of the unit
firmly up into
the cover until
the latch snaps into the
locked position.
Head/ight Wiring
The headlight wiring is protected by a
circuit breaker in the light switch. An
electrical overload will cause the lights
to go on and off, or in some cases to
remain off.
If this happens, have your
headlight system checked right away.
Windshield Wipers
The windshield wiper motor is protected
by a circuit breaker and
a fuse. If the
motor overheats due to heavy snow, etc.
,
the wiper will stop until the motor
cools. If the overload is caused by some
electrical problem, have it fixed.
Power Windows and Other
Power Options
Circuit breakers in the circuit
breakerhelay panel protect the power
windows and other power accessories.
When the current load is too heavy, the
circuit breaker opens and closes,
protecting the circuit until the problem
is fixed.
