KICKDOWN SERVO ADJUSTMENTr&?3~6
1. Completely remove all dirt and other materials adhered around the
kickdown servo switch.
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.
Caution

5. Loosen the locking nut to before the V groove of the
adjusting rod, and tighten ‘the special tool (inner) until it
contacts the locking nut.
6. Engage the special tool (outer) on the lock nut.
Rotating the outer cylinder counterclockwise and the inner
cylinder clockwise, lock the locking nut and special tool
(inner).
7. Attach the torque wrench to the special tool (inner), and repeat “tightening” and “returning” at a torque of 10 Nm
(7.2 ft.lbs.) two times. Then, tighten it to a torque of 5 Nm
(3.6
ft.Ibs.). Then, back off the special tool (inner) 2 to 2%
turns.

8. Engage the special tool (outer) on the locking nut.
Rotating the outer cyliner clockwise and the inner cylinder
counterclockwise, unlock the locking nut and special tool
(inner).
Caution
When unlocking the lock, apply equal force to both
tools.

9. Tighten the locking nut by hand until the locking nut
contacts the piston. Then, using the torque wrench, tighten
to the specified torque.
Locking 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.

7. Remove the valve body assembly. The manual valve can
come out, so be careful not to drop it.
8.Turn the adjustment screw of the regulator valve and adjust
so that the line pressure (kickdown brake pressure)
becomes the standard value.
When the adjustment screw is turned to the clockwise, the
line 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 turn of adjustment screw: 38
kPa (94 psi)
9. 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.
10. Replace the O-ring of the solenoid valve connector with a new one.
11. Install the valve body assembly to the case and then insert
the solenoid valve connector into the case. Be sure, at this
time, that the notched part of the connector faces as
shown in the figure.
Also be careful that the lead wiring isn’t caught.

12. Replace the O-ring of the solenoid valve harness with a new one.
13. Tilt the solenoid valve harness over from the inner side of
the transaxle case to the harness grommet installation hole’
and install the harness grommet securely.
14. Install the harness grommet so that the lead wiring of the solenoid valve harness faces in the direction indicated by
the arrow in the illustration. (FWD . . . From MODEL
1990.5)

15. Tighten valve body assembly mounting.
Valve body assembly mounting bolts:11 Nm (8.0 ftlbs.)
A: 18 mm (.709
in.) long
B: 25 mm (.984
in.) long
C: 40 mm (1.575 in.) long
Caution (AWD)
Fix the solenoid valve and oil temperature sensor harness
securely in the position shown. Since the harness of the
pressure control solenoid valve (PCSV) is separately
provided from the other harness, route the former
harness as illustrated and clamp it. If clamping is
forgotten, it will come into contact with the detent plate and parking rod.
16. Install the oil filter.
17. Install a new oil pan gasket and oil pan.
18. Pour in the specified amount of Automatic transaxle fluid.
19. Make the oil pressure test. Readjust if necessary.
REDUCING PRESSURE ADJUSTMENTMZ3FTAb
(If the scan tool 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.
