LINE PRESSURE ADJUSTMENT

1.

Discharge the automatic transmission fluid, and then
remove the valve body cover.

2.

Turn the adjusting screw shown in the illustration at left
to adjust the underdrive pressure to the standard value.
The pressure increases when the screw is turned to the
left.

NOTE
Adjusting to the middle of the standard value range when
the transmission is at the 1st or 2nd gear.

Standard value: 1,010 – 1,050 kPa

Change in pressure for each turn of the adjusting screw:
35 kPa

3.

Install the valve body cover, and pour in the standard
volume of automatic transmission fluid.

4.

Carry out a hydraulic pressure test. (Refer to P.23-51.)
Readjust the line pressure if necessary.

SELECTOR LEVER OPERATION CHECK

1.

Apply the parking brake, and check that the selector lever
moves smoothly and accurately to each range position.

2.

Check that the engine starts when the selector lever is
at the “N” or “P” position, and that it does not start when
the selector lever is in any other position.

3.

Start the engine, release the parking brake, and check
that the vehicle moves forward when the selector lever
is moved from “N” range to “1st” or “2nd” gear, and that
the vehicle reverses when the selector lever is moved
to  “R” range.

4.

Stop the engine.

5.

Turn the ignition switch to the “ON” position, and check
that the backup lamp illuminates and the buzzer sounds
when the selector lever is shifted from “P” to “R” range.

NOTE
The A/T key interlock and shift lock mechanism is provided
so that the selector lever cannot be moved from the “P”
position if the ignition switch is at a position other than
the  “LOCK (OFF)” position and the brake pedal is not
depressed.

KEY INTERLOCK MECHANISM CHECK

1.

Carry out the following check.

Inspection
procedure

Inspection conditions

Check details (Normal condition)

1

Brake pedal:
Depressed

Ignition switch position:
“LOCK (OFF)” or pulled
out

The selector lever cannot be moved from the “P” position
to any other position when the pushbutton on the
selector lever is not being pressed.

2

Ignition switch position:
Other than “LOCK (OFF)”
or pulled out

The selector lever can easily be moved from the “P”
position to some other position when the pushbutton on
the selector lever is being pressed.

3

Brake pedal:
Released

Selector lever position:
Other than “P”

The ignition switch will not turn to the “LOCK” position.

4

Selector lever position:
“P”

The ignition switch can turn smoothly to the “LOCK
(OFF)” position.

2.

When the above operations are defective, adjust the shift
lock cable as follows:
(1) Remove the front floor console, and then provisionally

install the selector lever knob.

(2) Move the selector lever to the “P” position.
(3) Turn the ignition key to “LOCK (OFF)” position.
(4) Loosen the locking nut of the key interlock cable.
(5) Push the cable joint on the lock cam gently toward

the arrow until the cable stops. Tighten the locking
nut.

Tightening torque: 12 Nm

(6) Install the floor console.

3.

After adjusting, check the operation once more. If the
operation is still incorrect, replace the key interlock cable.
(Refer to P.23-66.)
