23-92AUTOMATIC TRANSAXLE - Service Adjustment Procedures
NOTE
When adjusting the reducing pressure, aim for the center
value (425 kPa, 60 psi) of the standard value allowance.
Standard value: 415-435
kPa (59-62 psi)
Oil pressure change for each turn of adjustment screw: 22
kPa (3.1 psi) . . . FWD (Up to MODEL 1990)
45
kPa (6.4 psi) . . . FWD (From MODEL 1990.5, AWD)
3. Install the oil filter and oil pan in the same way as for adjustment of the line pressure.
4. Make the oil pressure test. Readjust if necessary.
(If the scan tool is used)
1. Using the scan tool, forcibly drive the pressure control
solenoid valve at 50% duty, and measure the kick-down
brake apply pressure.
If the kick-down brake apply pressure does not exist within
the standard value width, adjust the pressure with the
reducing pressure adjustment screw.
Standard value: 275 + 10 kPa (39 + 1 psi)
Oil pressure change for each turn of adjustment screw:
25 kPa (3.6 psi) FWD (Up to MODEL 1990)
22
kPa (3.1 psi) FWD (From MODEL 1990.5), AWD
2. Check to be sure that the reducing pressure (after the
adjustment is completed) is within the range of 360-480
kPa (51 -68 psi.).
Caution
This adjustment should be made at an oil
temperature
of 70- 80°C
(160- 180°F).
If the adjustment is made at a temperature that is too
high, the line pressure will drop during idling, with the
result that it might not be possible to make the correct
adjustment.

REMOVAL OF DRIVE SHAFT NUTLoosen the drive shaft nut while the vehicle is on the floor
with the brakes applied.
DISCONNECTION OF FRONT SPEED SENSOR
Remove the mounting bolts which hold the speed sensor
bracket to the knuckle, and then remove the speed
sensor.
Caution
Be careful when handling the pole piece at the tip of the
speed sensor and the toothed edge of the rotor so as
not to damage them by striking against other parts.
REMOVAL OF CALIPER ASSEMBLY
Remove the caliper assembly and suspend it with wires.
9. DISCONNECTION OF LOWER ARM BALL JOINT Using the special tool, disconnect the lower arm ball joint
from the knuckle.
Caution
1. Be sure to tie the cord of the special tool to the
nearby part.
2. Loosen the nut but do not remove it.
11. DISCONNECTION OF TIE ROD END
Using the special tool, disconnect the tie rod end from the
knuckle.
Caution
1. Be sure to tie the cord of the special tool to the
