EXTENSION HOUSING SEAL
REMOVAL & INSTALLATION
This seal controls transmission oil leakage around the driveshaft. Continued
failure of this seal usually indicates a worn output shaft bushing. If so, there will
be signs of the same wear on the driveshaft where it contacts the seal and
bushing. The seal is available and is fairly simple to install, with the proper tool.
1. Raise and safely support the rear of the vehicle to minimize transmission
oil loss when the driveshaft is removed.
2. Unbolt the driveshaft fr om the differential and center support bearing, if
equipped. Wrap tape around the bearing cu ps to keep them in place on
the universal joint and slide the sh aft out of the transmission.
3. Use an small pry tool to carefully pry out the old seal. Be careful not to
insert the tool too far into the hous ing or the bushing will be damaged.

CLUTCH

UNDERSTANDING THE CLUTCH
The purpose of the clutch is to disconnect and connect engine power at the
transmission. A vehicle at rest requires a lot of engine torque to get all that
weight moving. An internal combustion engine does not develop a high starting
torque (unlike steam engines) so it must be allowed to operate without any load
until it builds up enough torque to move the vehicle. To a point, torque
increases with engine rpm. The clutch a llows the engine to build up torque by
physically disconnecting t he engine from the transmission, relieving the engine
of any load or resistance.
The transfer of engine power to the tr ansmission (the load) must be smooth and
gradual; if it weren't, driv e line components would wear out or break quickly.
This gradual power transfer is made possi ble by gradually releasing the clutch
pedal. The clutch disc and pressure plat e are the connecting link between the
engine and transmission. When the clutch pedal is released, the disc and plate
contact each other (the clutch is engag ed) physically joining the engine and
transmission. When the pedal is pushed in, the disc and plate separate (the
clutch is disengaged) disconnecting the engine from the transmission.
Most clutch assemblies consists of t he flywheel, the clutch disc, the clutch
pressure plate, the throw out bearing and fork, the actuating linkage and the
pedal. The flywheel and clutch pressure plate (driving members) are connected
to the engine crankshaft and rotate with it. The clutch disc is located between
the flywheel and pressure plate, and is splined to the transmission shaft. A
driving member is one that is attached to the engine and transfers engine power
to a driven member (clutch disc) on t he transmission shaft. A driving member
(pressure plate) rotates (drives) a driv en member (clutch disc) on contact and,
in so doing, turns the transmission shaft.
There is a circular di aphragm spring within th e pressure plate cover
(transmission side). In a relaxed state (w hen the clutch pedal is fully released)
this spring is convex; that is, it is dished outward toward the transmission.
Pushing in the clutch peda l actuates the attached linkage. Connected to the
other end of this is the throw out fork, which hold the throw out bearing. When
the clutch pedal is depre ssed, the clutch linkage pushes the fork and bearing
forward to contact the diaphragm spring of the pressure plate. The outer edges
of the spring are secured to the pressure plate and are pivoted on rings so that
when the center of the spring is compre ssed by the throw out bearing, the outer
edges bow outward and, by so doing, pu ll the pressure plate in the same
direction - away from the clutch disc. This action se parates the disc from the
plate, disengaging the clutch and allowing the transmission to be shifted into
another gear. A coil type clutch return sp ring attached to the clutch pedal arm
permits full release of the pedal. Releasing the pedal pulls the throw out bearing
away from the diaphragm spring resulting in a reversal of spring position. As
bearing pressure is gradually released from the spring center, the outer edges

either hold the ring gear or allow it to rotate
The accumulators are used to cushi on the engagement of the servos. The
transmission fluid must pass through the ac cumulator on the way to the servo.
The accumulator housing contains a thin piston which is sprung away from the
discharge passage of the accumulato r. When fluid passes through the
accumulator on the way to the servo, it must move the piston against spring
pressure, and this action smooths out the action of the servo.
HYDRAULIC CONTROL SYSTEM
The hydraulic pressure used to operat e the servos comes from the main
transmission oil pump. This fluid is channel ed to the various servos through the
shift valves. There is generally a manual shift valve which is operated by the
transmission selector lever and an automat ic shift valve for each automatic
upshift the transmission provides.
Many new transmissions are electroni cally controlled. On these models,
electrical solenoids are used to better control the hydraulic fluid. Usually, the
solenoids are regulated by an electronic control module.
There are two pressures which affect t he operation of these valves. One is the
governor pressure which is effected by vehicle speed. The other is the
modulator pressure which is effected by intake manifold vacuum or throttle
position. Governor pressure rises wit h an increase in vehicle speed, and

DRIVELINE

DRIVESHAFT AND U-JOINTS
The U-joint is secured to the yoke in one of two ways. Dana and Cleveland
shafts use a conventional snapring to ho ld each bearing cup in the yoke. The
snapring fits into a groove located in eac h yoke end just on top of each bearing
cup. The Saginaw design shaft secures its U-joints in another way. Nylon
material is injected through a small hole in the yoke and flows along a circular
groove between the U-joint and the yoke , creating a synthetic snapring.
Disassembly of the Saginaw U-joint requi res the joint to be pressed from the
yoke. This results in damage to the be aring cups and destruction of the nylon
rings.

GM – CAMARO 1982-1992 – Repair Guide (Checked by WxMax) 323
Replacement kits include new bearing
cups and conventional snaprings to
replace the original nylon rings. These replacement rings must go inboard of the
yoke in contrast to outboard mounting of the Dana and Cleveland designs.
Previous service to the Saginaw U-joints can be recognized by the presence of
snaprings inboard of the yoke.
Bad U-joints, requiring replacement, will produce a clunking sound when the car
is put into gear. This is due to worn needle bearings or a scored trunnion end
possibly caused by improper lubricati on during assembly. Camaro U-joints
require no periodic maintenance and theref ore have no lubrication fittings.
DRIVESHAFT
REMOVAL & INSTALLATION 1. Raise the vehicle and safely su pport it on jackstands. Paint a reference
line from the rear end of the drives haft to the companion flange so that
they can be reassembled in the same position.
2. Disconnect the rear universal join t by removing the U-bolts, retaining
straps, or the flange bolts.
3. To prevent loss of the needle bear ings, tape the bearing caps to the
trunnion.

4. Remove the driveshaft from the tr ansmission by sliding it rearward.
Do not be alarmed by oil l eakage at the transmission output shaft. This oil is
there to lubricate the sp lines of the front yoke.
To install: 5. Check the yoke seal in the transmi ssion case extension and replace it if
necessary. See the transmission sect ion for replacement procedures.
6. Position the driveshaft and insert t he front yoke into the transmission so
the splines mesh with the transmission shaft splines.
7. Using reference marks made during re moval, align the driveshaft with the
companion flange and secure it with U-bolts or, retaining straps.
U-JOINT REPLACEMENT 1. Support the driveshaft horizontally in line with the base plate of a press.

ENGINE

MECHANICAL ENGINE
REMOVAL & INSTALLATION
In the process of removing the engine, you will come across a number of steps
which call for the removal of a separ ate component or system, such as
"disconnect the exhaust system " or "remove the radiator." In most instances, a
detailed removal procedure can be found elsewhere in this repair guide.
It is virtually impossible to list each individual wire and hose which must be
disconnected, simply because so many different model and engine
combinations have been manufactured. Careful observation and common
sense are the best possible approaches to any repair procedure.
Removal and installation of the engine ca n be made easier if you follow these
basic points:
• If you have to drain any of the fl uids, use a suitable container.
• Always tag any wires or hoses and, if possible, the components they
came from before disconnecting them.
• Because there are so many bolts and fasteners involved, store and label
the retainers from com ponents separately in muffin pans, jars or coffee
cans. This will prevent conf usion during installation.
• After unbolting the transmission or trans axle, always make sure it is
properly supported.
• If it is necessary to disconnect t he air conditioning system, have this
service performed by a qualified tec hnician using a recovery/recycling
station. If the system does not have to be disconnected, unbolt the
compressor and set it aside.
• When unbolting the engine mounts, a lways make sure the engine is
properly supported. When removing t he engine, make sure that any
lifting devices are properly attached to the engine. It is recommended
that if your engine is supplied with lifting hooks, your lifting apparatus be
attached to them.
• Lift the engine from its compartment sl owly, checking that no hoses,
wires or other component s are still connected.
• After the engine is clear of the compar tment, place it on an engine stand
or workbench.
• After the engine has been removed, y ou can perform a partial or full
teardown of the engine using the procedur es outlined in this repair guide.
