7-2 'DRIVETRAIN
Because of the way an internal combustron engine
breathes, it can produce torque, or twisting force,
only within a narrow speed range. Most modern,
overhead valve pushrod engines must turn at about
2500 rpm to produce their peak torque By 4500 rpm
they are producrng so lrttle torque that contrnued in-
creases in engine speed produce no power increases.
The torque peak on overhead camshaft engines IS
generally much higher, but much narrower.
The manual transaxle and clutch are employed to
vary the relationship between engine speed and the
speed of the wheels so that adequate engine power can
be produced under all crrcumstances. The clutch al-
lows engine torque to be applied to the transaxle input
shaft gradually, due to mechanical slippage. Conse-
quently, the vehicle may be started smoothly from a
full stop The transaxle changes the ratio between the
rotating speeds of the engine and the wheels by the
use of gears. The gear ratios allow full engine power to
be applied to the wheels during acceleration at low
speeds and at highway/passing speeds.
In a front wheel drive transaxle, power is usually
transmitted from the input shaft to a mainshaft or out-
put shaft located slightly beneath and to the side of
the input shaft. The gears of the mainshaft mesh with
gears on the input shaft, allowing power to be carried
from one to the other. All forward gears are in con-
stant mesh and are free from rotating with the shaft
unless the synchronizer and clutch IS engaged. Shaft-
ing from one gear to the next causes one of the gears
to be freed from rotating with the shaft and locks an-
other to it. Gears are locked and unlocked by internal
dog clutches which slide between the center of the
gear and the shaft. The forward gears employ syn-
chronizers; friction members which smoothly bring
gear and shaft to the same speed before the toothed
dog clutches are engaged.
SHIFT LINKAGE
1. Disconnect the shift linkage from the transaxle.
2. On the transaxle, put select lever in N and
move the shift lever in
4th gear. Depress the clutch,
if necessary, to shift.
3. Move the shift lever in the vehicle to the
4th gear position until it contacts the stop.
4. Turn the adjuster turnbuckle so the shift cable
eye aligns with the eye in the gear shift lever. When
installing the cable eye, make sure the flange side of
the plastic bushing at the shift cable end is on the
cotter pin side.
5 The cables should be adjusted so the clear-
ance between the shift lever and the 2 stoppers are
equal when the shift lever IS moved to 3rd and 4th
gear. Move the shift lever to each positron and check i
that the shifting is smooth

the transaxle housing. On some 1.5L engines, in-
stead of a pushrod bearing against the clutch arm, a
clevis pin and yoke is used. Simply remove the cir-
clip, pull out the clevis pin and remove the cylinder.
5. The installation IS the reverse of the removal
procedure.
6. Lubricate all pivot points with grease.
7. Bleed the system using DOT 3 brake fluid.

) See Figure 43
With Hydraulic Clutch
1, Fill the reservoir with clean brake fluid meeting
DOT 3 specificatrons.
Clean, high quality brake fluid is essential to
the safe and proper operation of the brake
system. You should always buy the highest
quality brake fluid that is available. If the
brake fluid becomes contaminated, drain and
flush the system, then refill the master cylin-
der with new fluid. Never reuse any brake
fluid. Any brake fluid that is removed from
the system should be discarded. Also, do not
allow any brake fluid to come in contact with
a painted surface; it will damage the paint.
2. Press the clutch pedal to the floor, then open
the bleeder screw on the slave cvlinder.
3. Tighten the bleed screw and release the clutch
pedal.
4. Repeat the procedure until the fluid is free of
air bubbles.

The automatic transaxle allows engine torque and
power to be transmitted to the front wheels within a
narrow range of engine operating speeds. It will allow
the engine to turn fast enough to produce plenty of
power and torque at very low speeds, while keeping it
at a sensible rpm at high vehicle speeds (and it does
this job without driver assistance). The transaxle uses
a light fluid as the medium for the transmission of
power. This fluid also works in ths operation of vari-
ous hydraulic control circuits and as a lubricant. Be-
cause the transaxle fluid performs all of these func-
tions, trouble within the unit can easily travel from one
part to another For this reason, and because of the
complexity and unusual operating principles of the
transaxle, a very sound understanding of the basic
principles of operation will simplify troubleshooting
