(d) Replace the ATF.
NOTICE:
Do not overfill.
(1) Using a 10 mm hexagon wrench, remove the drain
plug, gasket and drain the fluid.
(2) Install a new gasket and the drain plug securely.
(3) Add new fluid through the filler pipe.
Fluid type: ATF type T or equivalent
Drain and refill: 3.3 liters (3.5 US qts, 2.9 lmp. qts)
(4) Start the engine and shift the selector into all the
positions from P through L and then shift into the P
position.
(5) With the engine idling, check the fluid level. Add
fluid up to the COOL level on the dipstick.
(6) Check the fluid level with the normal fluid tempera-
ture 70 − 80°C (158 − 176°F) and add as neces-
sary.
NOTICE:
Do not overfill.
(e) Replace the transfer oil.
(1) Using a 10 mm hexagon wrench, remove the drain
plug and drain the oil.
(2) Install the drain plug.
(3) Add new oil through the filler pipe.
Recommended oil:
Oil grade API GL−5
Viscosity SAE 75W−90
Capacity: 0.7 liters (0.7 US qts, 0.6 lmp. qts)
(4) Check the oil level and add as necessary.

(f) Check the fluid leaks.
Check for leaks in the transmission and transfer.
If there are leaks, it is necessary to repair or replace O − rings,
FIPG’s, oil seals or other parts.
(g) Inspect and adjust the throttle cable.
(1) Check that the throttle valve is fully closed.
(2) Check that the inner cable is not slack.
(3) Loosen the adjustment nuts.
(4) Adjust the outer cable so that the distance between
the end of the boot and stopper on the cable is as
standard.
Standard boot and cable stopper distance:
0 − 1 mm (0 − 0.04 in.)
(5) Tighten the adjusting nuts.
(6) Recheck the adjustments.
(h) Adjust the shift control cable.
(1) Loosen the nut on the lever.
(2) Push the manual lever fully toward the right side of
the vehicle.

CAUTION:
Perform the test at normal operating ATF temperature 50 − 80°C (122 − 176°F).
The line pressure test should always be carried out in parts. One should observe the conditions
of wheels or wheel stopper outside the vehicle while the other is performing the test.
(b) Measure the line pressure.
(1) Fully apply the parking brake and chock the 4 wheels.
(2) Start the engine and check idling speed.
(3) Step down strongly on the brake pedal with your left foot and shift into the D position.
(4) Measure the line pressure when the engine is idling speed.
(5) Press the accelerator pedal all the way down. Quickly read the highest line pressure when engine
speed reaches stall speed.
(6) Only when the shift solenoid valve ST is opened:
Apply battery positive voltage between terminal of the solenoid connector and body ground.
(7) In the same way, perform the test in the R position.

*: When battery voltage is supplied to terminal 4 of the solenoid connector and body ground, the shift sole-
noid valve ST valve is open.
If the measured pressures are not with in the specification, recheck the throttle cable adjustment and perform
a retest.

11. MANUAL SHIFTING TEST
HINT:
With this test, it can be determined whether the trouble is within
the electrical circuit or is a mechanical problem in the transaxle.
(a) Disconnect the solenoid wire.
(b) Inspect the manual driving operation.
Check that the shift and gear positions correspond with
the table below.

PROBLEM SYMPTOMS TABLE
If a normal code is displayed during the diagnostic trouble code check but the trouble still occurs, check the
circuits for each symptom in the order given in the charts on the following pages and proceed to the page
given for troubleshooting.
The Matrix Chart is divided into 3 chapters.
Chapter 1: Electronic Circuit Matrix Chart
Chapter 2: On−Vehicle Repair Matrix Chart
Chapter 3: Off−Vehicle Repair Matrix Chart
When troubleshooting, check Chapter 1 first. If instructions are given in Chapter 1 to proceed to chapter 2
or 3, proceed as instructed.
(1) If the instruction ”Proceed to next circuit inspection shown on matrix chart” is given in the flow
chart for each circuit, proceed to the circuit with the next highest number in the table to continue
the check.
(2) If the trouble still occurs even though there are no abnormalities in any of the other circuits, then
check and replace the ECM.
