1993 CADILLAC ELDORADO torque

Downloaded from www.Manualslib.com manuals search engine GARAGE DOOR OPENER (OPTION)
This option allows you
to open up to three
garage doors. The transmitter unit fits the
overhead panel.
Your Cadillac dealer can tell you about the hand held power pack unit
and the installation you’ll need at home to make this work.
If your
CadilIac
is equipped with an Electriclear” heated windshield, you’ll have
to be closer to the garage door for the transmitter unit
to work.
FLOOR MATS
If your Cadillac is equipped with rubber-backed front and rear floor mats,
keep them clean by vacuuming and using a spot cleaner,
if necessary. Do
not machine wash.
TRACTION CONTROL SYSTEM (4.4L
NORTHSTAR)
Your traction control system operates only when the system senses that
one or both of the front wheels
is spinning or beginning to lose traction
while driving. This is especially useful
in slippery road conditions. The
traction control system works at all speeds.
It limits wheel spin by using
the antilock and brake systems to apply the front brakes and by shutting
off
fuel injectors to reduce engine torque.
You may be able to spin the tires when accelerating from a standstill on
dry pavement. This is normal. The “TRACTION ACTIVE” message will

when you’re parking
uphill, turn the wheels

If there
is no curb when you’re parking uphill on the left side of a
one-way street, your wheels should be turned to the left.
Torque Lock (Automatic Transaxle)
If you are parking on a hill and you don’t shift your transaxle into “P”
(Park) properly, the weight of the vehicle may put too much force on the
parking pawl
in the transaxle. You may find it difficult to pull the shift
lever out
of “P” (Park). This is called “torque lock.” To prevent torque
lock, always be sure
to shift into “P” (Park) properly before you leave the
driver’s seat.
To find out how, see “ Shifting Into ’P’ (Park)” in the Index.

Downloaded from www.Manualslib.com manuals search engine If “torque lock” does occur, you may need to have another vehicle push
yours a little uphill to take some
of the pressure from the transaxle, so
you can pull the shift lever out of “P” (Park).
WINTER DRZVTNG
Here are some tips for winter driving:
0 Have your Cadillac in good shape for winter. Be sure your engine
0 Snow tires can help in loose snow, but they may give you less traction
on ice than regular tires.
If you do not expect to be driving in deep
snow, but may have to travel over ice, you may not want
to switch to
snow tires at all.
coolant
mix is correct.
0 You may want to put winter emergency supplies in your trunk.

Tighten the wheel
nuts firmly in a
criss-cross sequence
as shown.
A CAUTION:
Incorrect wheel nuts or improperly tightened wheel nuts can
cause the wheel to become loose and even come
off. This could
lead to an accident. Be sure to use the correct wheel nuts.
If you
have to replace them, be sure to get the right kind.
Stop somewhere as soon as you can and have the nuts tightened
with a torque wrench to

Downloaded from www.Manualslib.com manuals search engine This transaxle is the first of a new generation of “SMART” transmissions.
The computer which controls the electronic shift solenoids adapts to
changing environments while you drive. This provides consistent high
quality shifts under all conditions. Communication between the engine
and transaxle through this computer controls engine output durin\
g
activation
of torque management or traction control. Smooth shifting is
ensured by design. Hydraulic accumulators control shift pressures and all
shifts are made to free wheeling elements.
The 4T80E uses a dry sump lubrication system with a scavenger pump.
This unique feature enables the transaxle to maintain adequate
pressurized oil supply during
all maneuvers.
Spirited performance with
very efficient cruising operation are provided
by the combination
of 4 speed overdrive gearing, a torque converter
clutch, and a
3.71:l or 3.11:l final drive ratio.
4T60-E Transaxle (4.9 L Eldoradu)

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, and 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 vein type
pump provides the working pressure needed to operate the friction
elements and automatic controls.

The power rack and pinion steering system,has a rotary spool valve which
directs hydraulic fluid coming from the power steering pump
to one side
or the other side
of the rack piston. The integral rack piston is attached to
the rack. The rack piston converts hydraulic pressure
to a linear force
which moves the rack left or right. The force
is then transmitted through
the inner and outer tie rods to the steering knuckles, which turn the
wheels
If hydraulic assist is not available, manual control is maintained. However
under these conditions more steering effort
is required.
