INHIBITOR SWITCH ADJUSTMENTNZlFKAJ
INHIBITOR SWITCH1. Place selector lever in “N” (Neutral) position.
2. Place manual control lever in “N” (Neutral) position.
3.To adjust, rotate the switch body so that the manual controllever 5 mm
(2 in.) hole and the switch body 5 mm (.2 in.)
hole are aligned.
4.Tighten the mounting bolts of the inhibitor switch body to
the specified torque. At this time, take care to prevent
dropping the switch body.
Specified torque:
lo-12 Nm (7-9 ftlbs.)
5.Loosen the nut shown in the figure, and lightly pull the end
of the transaxle control cable in the “F” direction by hand.
6. Tighten the nut to the specified torque.
Specified torque:
IO-14 Nm (7-10 ftlbs.)7. Check that the selector lever is in “N” position.
8. Check that it securely operates and functions on the
transaxle side in the range which corresponds to each
position of the selector lever.

KICKOOWN SERVO ADJUSTMENTNZlFRAB1. Completely remove all dirt and other materials adhered
G+around the kickdown servo switch.
-i-s-2. Remove the snap ring.
3. Remove the kickdown servo switch.
4. To prevent rotation of the piston, engage the
pawl of the
special tool into the notch of the piston, and using the
adapter, fix the piston as shown in the left.
Caution1. Don’t press in the piston with the special tool.
2.When mounting the adapter on the transaxle case,
tighten it by hand. Don’t apply much torque.
5.Loosen the lock nut to before the V groove of the adjusting
rod, and tighten the special tool (inner) until it contacts the
lock nut.
6. Engage the special tool (outer) on the lock nut.
Rotating the outer cylinder counterclockwise and the inner
cylinder clockwise, lock the lock nut and special tool (inner).7. Attach the torque wrench to the special tool (inner), and
repeat “tightening” and “returning” at a torque of
IO Nm
(7.2
ft.lbs.) two times. Then, tighten it to a torque of 5 Nm
(3.6
ftlbs.). Then, back off the special tool (inner) 2 to 2%
turns.*

AUTOMATIC TRANSAXLE - Service Adjustment Procedures21-2138. Engage the special tool (outer) on the lock nut.
Rotating the outer cyliner clockwise and the inner cylinder
counterclockwise, unlock the lock nut and special tool
(inner).Caution
When unlocking the lock, apply equal force to bothtools.
9.Tighten the lock nut by hand until the lock nut contacts the
piston. Then, using the torque wrench, tighten to the
specified torque.
Lock nut: 25-32 Nm (18-23 ft.lbs.)
Caution
If it is rapidly tightened with the socket wrench or
torque wrench, the lock nut and adjusting rod may
rotate together.
10. Remove the special tool which fastens the piston.
Attach the plug to the outlet of the low reverse pressure.
LINE PRESSURE ADJUSTMENTN2lFSABl
1. Drain out the automatic transaxle fluid.
2. Remove the oil pan.
3. Remove the oil filter.
4. Remove the oil-temperature sensor.
5. Press the solenoid valve harness grommet and connector
into the transaxle case.
6. Remove the valve body assembly. The manual valve can
come out, so be careful not to drop it.

7.Turn the adjustment screw of the regulator valve and adjustso that the line pressure
(kickdown brake pressure) a,becomes the standard value.
When the adjustment screw is turned to the clockwise, the
Lline pressure becomes lower; when it is turned to
counter-clockwise, it becomes higher.
Standard value:
870-890 kPa (124-127 psi)
Oil pressure change for each turq of
adjustment screw: 38
kPa (54 psi)
8. Check to be sure that the O-ring is installed on the upper
surface of the valve body at the place shown in the figure.
9.Replace the O-ring of the solenoid valve harness grommet
with a new one.
10. Insert the solenoid valve harness grommet in the axle case.
11. Install the valve body and oil temperature sensor, and then

REDUCING PRESSURE ADJUSTMENTNZlFTAC(If the multi-use tester is not available)
1. Remove parts up to the oil filter in the same way as for
adjustment of the line pressure. The valve body need not
be removed.
+%2. Turn the adjustment screw of the lower valve body and_adjust so that the reducing pressure is the standard value.
When the adjustment screw is turned to the right, the
reducing pressure becomes lower; when it is turned to the
left, it becomes higher.

NOTEWhen adjusting the reducing pressure, aim for the center
value (425

2.Install the grommet so that, as shown in the illustration, thecable attachment is positioned upward.
Caution
1.The cable arrangement should be made so that the
radius of cable bends is 150 mm (5.9 in.) or more.
2.The arrangement of the speedometer cable should
be such that it does not interfere with other parts.
3. At the transaxle end of the speedometer cable, the key
joint should be inserted into the transaxle, and the nut
should be securely tightened.
Caution
“ccIf the cable is not correctly and securely connected, it
may cause incorrect indication by the speedometer, or
abnormal noise. Be sure to connect it correctly.
