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

*If the vehicle is going to be roiled while the
halfshafts are out of the vehicle, obtain 2 outer
CV-joints or proper equivalent tools and install
to the hubs. If the vehicle is rolled without the
proper torque applied to the front wheel bear-
ings, the bearings will no longer be usable.
*The suspension components should not be
tightened until the vehicles weight is resting
on the ground.

14 Disconnect the clutch cable, if equipped with
cable controlled clutch system.
15. Remove the halfshafts by inserting a prybar
between the transaxle case and the driveshaft and
prying the shaft from the transaxle. Do not pull on the
driveshaft Doing so damages the inboard joint. Do
not insert the prybar so far the oil seal in the case is
damaged.
*It is not necessary to disconnect the half-
shafts from the steering knuckle. Remove the
shaft with the hub and knuckle as an assem-
bly. Tie the shafts aside. Note the circle clip
on the end of the inboard shafts should not
be reused.

3. Place a suitable drain pan under the vehicle to
catch the fluid once the line IS drsconnected, or place
a rag or shop towel under the fluid line of the master
cylinder.
4. Loosen the line at the cylinder and allow the
fluid to drain.
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 oainted surface; it will damage the paint.
5. Remove the clevis pin retainer at the clutch
pedal and remove the washer and clevis pm.
6. Remove the 2 nuts and pull the cylinder from
the firewall. A seal should be between the mounting
flange and firewall. This seal should be replaced.
7. The installation is the reverse of the removal
procedure.
8. Lubricate all pivot points with grease.
9. Bleed the system at the slave cylinder using
DOT 3 brake fluid and check the adjustment of the
clutch pedal.

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
