SERVO ADJUSTMENT
1. Completely remove all dirt and other materials adhered
around the
servo switch.
2. Remove the snap ring.
3. Remove the
servo switch.
4. To prevent rotation of the piston, engage the
of
the special tool into the notch of the piston, and using
the adapter, secure the piston as shown to the left .
Caution
1Don’t press in the piston with the special tool.
2.When mounting the adapter on the transaxle case,
tighten it by hand. Do not overtighten.
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 t ool (in-
ner).
7. Attach a torque wrench to the special tool (inne r) and
tighten to a torque of 10 Nm (7.2
and repeating
“Tighten” and “Loosen” two times then torque to 5 N m
(3.6
After that, back off the special tool (inner)
2 to
turns.
8. Engage the tool (outer) on the lock nut.
Rotating the outer cylinder clockwise and the inner cylinder
counterclockwise, unlock the lock nut and special ‘tool
(inner).
Caution
When unlocking the nut and special tool, apply equa l
force to both parts.

9. Tighten the lock nut by hand until the lock nut contacts
the piston. Then using the torque wrench, tighten t o the
specified torque.
Lock nut: (21
Caution
If it is rapidly tightened with the socket wrench o r
torque wrench, the lock nut and adjusting rod may
rotate together.
10. Remove the special tool which fastens the pisto n.
Attach the plug to the outlet of the low-reverse pressure.

1. Drain out the automatic transmission 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 connec tor
into the transaxle case.
6.Press the catches of the solenoid valve harness grommets
and pass the connector through the case hole.
7.Remove the valve body assembly. The manual

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 clockwise, the line
pressure decreases; when it is turned to counterclockwise,
it increases.
Standard value: psi)
Oil pressure change for each turn of adjustment

9. Check 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 harnes s grommet
with a new one.
11. Pass the solenoid valve connector through the i nside
of the hole in the case.
