MANUAL TRANSMISSION

UNDERSTANDING THE MANUAL TRANSMISSION
Because of the way an internal combus tion engine breathes, it can produce
torque (or twisting force) only withi n a narrow speed range. Most overhead
valve pushrod engines must turn at about 2500 rpm to produce their peak
torque. Often by 4500 rpm, they are prod ucing so little torque that continued
increases in engine speed produce no power increases.
The torque peak on overhead camshaft engines is, generally, much higher, but
much narrower.
The manual transmission and clutch are employed to vary the relationship
between engine RPM and the speed of the w heels so that adequate power can
be produced under all circumst ances. The clutch allows engine torque to be
applied to the transmission input shaft gradually, due to mechanical slippage.
The vehicle can, consequently, be star ted smoothly from a full stop.
The transmission changes the ratio between the rotating speeds of the engine
and the wheels by the use of gears. 4-speed or 5-speed transmissions are most
common. The lower gears al low full engine power to be applied to the rear
wheels during acceleration at low speeds.
The clutch driveplate is a thin disc, the center of which is splined to the
transmission input shaft. Both sides of the disc are covered with a layer of
material which is similar to brake li ning and which is capable of allowing
slippage without roughness or excessive noise.
The clutch cover is bolted to the engine flywheel and incorporates a diaphragm
spring which provides the pressure to engage the clutch. The cover also houses
the pressure plate. When the clutch pe dal is released, the driven disc is
sandwiched between the pressu re plate and the smooth surface of the flywheel,
thus forcing the disc to turn at th e same speed as the engine crankshaft.
The transmission contains a mainshaft which passes all the way through the
transmission, from the clutch to the dr iveshaft. This shaft is separated at one
point, so that front and rear portions can turn at different speeds.
Power is transmitted by a countershaft in the lower gears and reverse. The
gears of the countershaft mesh with gear s on the mainshaft, allowing power to
be carried from one to the other. Countershaft gears are often integral with that
shaft, while several of the mainshaft gea rs can either rotate independently of
the shaft or be locked to it. Shifting from one gear to the next causes one of the
gears to be freed from rotating with the shaft and locks another to it. Gears are
locked and unlocked by internal dog clutc hes which slide between the center of
the gear and the shaft. The forward gears us ually employ synchronizers; friction

members which smoothly bring gear and
shaft to the same speed before the
toothed dog clutches are engaged.

4. Remove the switch attaching bo
lt and remove the clutch switch.
5. Installation is the reverse of t he removal procedure. The switch will
automatically adjust when depres sed for the first time.
SPEED SENSOR
REMOVAL & INSTALLATION
5-SPEED TRANSMISSION 1. Disconnect the negative battery cable.
2. Disconnect the electrical connector.
3. Remove the attaching bolt and remove the sensor.
4. Installation is the reverse of the removal procedure. The bolt torque is 89
inch lbs. (10 Nm).
SHIFT HANDLE
REMOVAL & INSTALLATION 1. Disconnect the negative battery cable.
2. Raise and safely support the vehicle.
3. Disconnect the shift rods from the control lever.
4. Lower the vehicle. Remove the shifter knob.
5. Remove the parking lever grip.

6. Remove the console cover.
7. Remove the shifter boot.
8. Remove the shifter mounting bolt
s and remove the shifter assembly.
9. Installation is the reverse of the removal procedure. Adjust the linkage as
detailed earlier.
BACK-UP LIGHT SWITCH
REMOVAL & INSTALLATION 1. Disconnect the negative battery terminal from the battery.
2. At the left-rear of the transmission, the back-up light switch is threaded
into the transmission case. The speed sensor is held in with a separate
bracket. Disconnect the electrical co nnector from the back-up light
switch.
3. Remove the back-up light swit ch from the transmission.
4. To install, reverse the remova l procedures. Coat the threads with
Teflon® tape. Please refer to the to rque chart for specifications. Place
the gear shift lever in the revers e position and check that the back-up
lights work.
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.

4. Use an oil seal installation tool to evenly drive the new seal into the
housing. Make sure the tool only cont acts the outer metal portion of the
seal.
5. Install the driveshaft. Torque the uni versal bearing cup retainer bolts to
15 ft. lbs. (20 Nm).
TRANSMISSION
REMOVAL & INSTALLATION
On 5-speed transmissions remove the shif t lever boot and the shift lever prior to
transmission removal.
1. Disconnect the negative batte ry cable at the battery.
2. Raise the vehicle and support it safely with jackstands.

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
