Bolt A
= Length 18 mm (.709 in.)
Bolt B
= Length 25 mm (.984 in.)
Bolt C
= Length 40 mm (1.575 in.)
CautionSecure solenoid valve and oil temperature sensor
harness at locations shown.
(1O)lnstall oil filter.(1l)lnstall new oil pan gasket and oil pan.
(12)Add the specified amount of ATF.
(13)Carry out hydraulic test.
Readjust as necessary.
REDUCING PRESSURE ADJUSTMENTh323FfADWhen multi-use tester is not used
(1) Following the same steps as those in line pressure
adjustment, remove parts up to oil filter.
There is no need to remove valve body.
(2) Turn adjusting screw of lower valve body to obtain the
specified reducing pressure. Turn it counterclockwise to
increase the pressure.
Standard value:425 f 10 kPa (60 f 1 psi)
Oil pressure change for
each turn of adjusting screw:45 kPa (6 psi)(3) In the same way as in line pressure adjustment,
/nstall oil
filter and oil pan.
(4) Perform hydraulic test.
Adjust as necessary.
When multi-use tester is used
(1) Adjust to obtain the specified K/D brake pressure when PC
solenoid is energized at duty 50% with the multi-use tester.
Standard value:275 kPa (39 psi)
Oil pressure change for
each turn of adjusting screw:50 kPa (7 psi)(2) After adjustment has been made, check that the recuding
pressure is in the range 360
- 480 kPa (51 - 68 psi).
Caution
This adjustment should be made with oil temperature70
- 80°C (160 - 180°F).
The adjustment made with high oil temperature couldresult in improper adjustment due to a line pressure
drop at idle.

SELECTOR LEVER OPERATION CHECKM23FIAG
1.. Shift selector lever to each range and check that lever
moves smoothly and is controlled. Check that position
indicator is correct.
2.Check to be sure the selector lever can be shifted to each
position (by button operation as shown in the illustration).
3. Start the engine and check if the vehicle moves forward
dwhen the selector lever is shifted from N to
D, and moves
backward when shifted to R.
4.When the shift lever malfunctions, adjust control cable and
selector lever sleeve. Check for worn shift lever assembly
sliding parts.

NOTETo move the selector lever from the “P” position to any
other position, first turn the ignition key to any position
other than “LOCK” and depress the brake pedal.
KEY INTERLOCK MECHANISM CHECKM23FlJACCompletely stop the vehicle and switch OFF the engine before
making the check
1.Check to be sure that, under the following conditions, the
selector lever cannot be moved from the “P” position to
any other position.
Also check, at the same time, that the button cannot be
pressed.

other position.
Press the button a few times and check to be sure that the
selector lever moves smoothly.

3.Check to be sure that, at all positions of the selector lever
(other than “P”), the ignition key cannot be turned to the
“LOCK” position.
Check to be sure that the ignition key smoothly turns to the
“LOCK” position when the selector lever is then set to the
“P” position and the button is released.
4. If above are not checked okay, adjust key interlock cable
mechanism as follows.
(1) Remove front console assembly.
(2) Place selector lever into “P” position.
(3) Turn ignition key to the “LOCK” position.
(4) Loosen nut that secures key interlock cable.
(5) Lightly pressing lock cam A in the direction of arrow,
lightly push key interlock cable to take up slack and
tighten nut to secure key interlock cable.
