Operating the engine with the air cleaner off can cause you or
others
to be burned. The air cleaner not only cleans the air, it
stops flame if the engine backfires.
If it isn’t there, and the
engine backfires, you could be burned. Don’t drive
with it off,
and be careful working on the engine with the air cleaner off.

NOTICE:
If the air cleaner is off, a backflre can cause a damaging tngine
fire, And, dirt can easily get into your engine, which will drmagc
it, Always have the air cleaner io place when you’rt ddvlng.
AUTOMTIC 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 “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 a Cadillac 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.

3. Check both sides of the dipstick, and read the lower level. The fluid
level must be in the cross-hatched area.
4. If the fluid level is where it should be, push the dipstick back in all the

way.
Refer to the Maintenance Schedule to determine what kind
of transaxle
fluid to
use. See “Recommended Fluids and Lubricants” in the Index.
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. 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@-IIE is not covered
by your new vehicle warranty.
After adding fluid, recheck the fluid level as described under “How to
Check.”

Downloaded from www.Manualslib.com manuals search engine The Hydra-matic 4T60-E 4-speed overdrive, electronic transaxle consists
primarily of a five element torque converter;
two planetary gear sets,
various clutches, final drive assembly, differential assembly, an\
d a control
valve body.
The torque converter houses a pump, turbine, pressure plate which is
splined to the turbine, and a stator assembly, serving as a fluid coupling, it
smoothly transmits power
from the engine to the transaxle. It also
hydraulically provides additional torque
when required. When applied,
the pressure plate provides a mechanical direct drive coupling of the
engine to the transaxle.
The
two planetary gear sets provide the four forward gear ratios and
reverse. Changing of the gear ratios is
fully automatic and is
accomplished through the use
of various electronic and mechanical
requirements. Four multiple disc clutches,
two roller clutches, a sprag
clutch, and three bands provide the friction elements required to obtain
the various ratios with the planetary gear sets.
A hydraulic system (the control valve body), pressurized by a vane type
pump provides the working pressure needed to operate the friction
elements and automatic controls.

Downloaded from www.Manualslib.com manuals search engine Front Suspension
Your fully independent front suspension is a combination strut and sp~
design. The frame is isolated from the body with six rubber mounts. -ing
Rubber bushings are used at the lower control arm pivots. The upper
end
of the strut is isolated by a rubber mount which contains a bearing to
allow for wheel turning. The Road Sensing Suspension
on the STS and
the Speed Sensing Suspension on Seville
will automatically controls the
damping rate
of the struts.
The lower end
of the steering knuckle pivots on a ball joint riveted to the
control arm. The ball joint is connected to the steering knuckle with a
castellated nut and cotter pin.
