1994 CADILLAC ELDORADO torque

Downloaded from www.Manualslib.com manuals search engine Torque Lock
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, set the parking brake and then shift into
“P” (Park) properly before
you leave the driver’s seat.
To find out how, see “Shifting Into ‘P’ (Park)”
in the Index.
If ‘?.orque 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).

men It’s Time for New Tires
One way to tell when
it’s time for new tires is
to check
the treadwear
indicators, which
will
appear when your tires
have
only,2/32 inch
(1.6 mm) or less of
tread remaining.
Youneed a new
tire if:.
You can see the indicators at three or more -places around the tire.
You can .see cord or fabric showing through the tire’s rubber.;
The tread-or sidewall is cracked, cut or snagged deep enough to show
cord or fabric.

4T80-E Transaxle
r
The 4T80-E transaxle has been designed to complement the output
characteristics
of the Northstar engine. The innovative design
incorporates several features which enhance its overall operation.
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 during
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 clutch, with a -
3.71:l final drive on the ETC and a viscous torque converter clutch with a a
3.1 1:l final drive ratio on the Eldorado.
Front Suspension
..
Your fully independent front suspension is a combination strut and spring
design. The frame is isolated from the body with
six rubber mounts.
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 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.

The power rack and pinion..stee&g .gstem--h,w, a ,rotaq- 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 rack4eft 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 conirol, is ‘maintained. However
under these, conditions. more steering effort is required.
