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.

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
(IO pieces) to
tighten valve body assembly mounting bolts

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.

AUTOMATIC TRANSAXLE - Service Adjustment Piocedures21-215
NOTEWhen adjusting the reducing pressure, aim for the center
value (425
kPa, 60 psi) of the standard value allowance.
Standard value:
