(c) Replace the ATF.
(1) Remove the drain plug and drain the fluid.
(2) Reinstall the drain plug securely.
(3) With the engine OFF add new fluid through the oil
filler pipe.
Fluid type: ATF D±II or DEXRON®III (DEXRON®II)
Capacity: 2.5 liters (2.6 US qts, 2.1 Imp. qts)
(4) Start the engine and shift the shift lever into all posi-
tions from P to L position and then shift into P posi-
tion.
(5) With the engine idling, check the fluid level. Add
fluid up to the COOL level on the dipstick.
(6) Check the fluid level is at the normal operating tem-
perature, 70 ± 80 °C (158 ± 176 °F), and add as
necessary.
NOTICE:
Do not overfill.
(d) Check the fluid leaks.
Check for leaks in the transaxle.
If there are leaks, it is necessary to repair or replace O±rings,
gasket, oil seals, plugs or other parts.
(e) Inspect and adjust the throttle cable.
(1) Check that the accelerator pedal is fully released.
(2) Check that the inner cable is not slack.
(3) Measure the distance between the outer cable end
and stopper on the cable.
Standard distance: 0 ± 1 mm (0 ± 0.04 in.)
If the distance is not standard, adjust the cable by the adjusting
nuts.

(f) Inspect and adjust the shift lever position.
When shifting the shift lever from the N position to other
positions, check that the lever can be shifted smoothly
and accurately to each position and that the position indi-
cator is aligned with the correct position.
If the indicator is not aligned with the correct position, carry out
the following adjustment procedures.
(1) Loosen the nut on the shift lever.
(2) Push the control shaft fully rearward.
(3) Return the control shaft lever 2 notches to N posi-
tion.
(4) Set the shift lever to N position.
(5) While holding the shift lever lightly toward the R
position side, tighten the shift lever nut.
Torque: 13 N´m (130 kgf´cm, 9 ft´lbf)
(6) Start the engine and make sure that the vehicle
moves forward when shifting the lever from the N to
D position and reverses when shifting it to the R
position.
(g) Inspect and adjust the park/neutral position.
Check that the engine can be started with the shift lever
only in the N or P position, but not in other positions.
If it is not as stated above, carry out the following adjustment
procedures.
(1) Loosen the park/neutral position switch bolt and set
the shift lever to the N position.
(2) Align the groove and neutral basic line.
(3) Hold the switch in position and tighten the bolt.
Torque: 5.4 N´m (55 kgf´cm, 48 in´lbf)
For continuity inspection of the park/neutral position
switch, see page DI±165.
(h) Check the idle speed.
Idle speed : 700 ± 50 rpm
(In N position and air conditioning OFF)

6. MECHANICAL SYSTEM TESTS
(a) Measure the stall speed.
The object of this test is to check the overall performance of the transaxle and engine by measuring
the stall speeds in the D and R positions.
NOTICE:

Do the test at normal operating fluid temperature 50 ± 80 °C (122 ± 176 °F).

Do not continuously run this test for longer than 5 seconds.

To ensure safety, conduct this test in a wide, clear level area which provides good traction.

The stall test should always be carried out in pairs. One technician should observe the condi-
tions of wheels or wheel stoppers outside the vehicle while the other is doing the test.
(1) Chock the 4 wheels.
(2) Connect an OBD II scan tool or hand±held tester to DLC3.
(3) Fully apply the parking brake.
(4) Keep your left foot depressing firmly on the brake pedal.
(5) Start the engine.
(6) Shift into the D position. Press all the way down on the accelerator pedal with your right foot.
Quickly read the stall speed at this time.
Stall speed: 2,450 ± 150 rpm
(7) Do the same test in R position.
Stall speed: 2,450 ± 150 rpm
Evaluation:
ProblemPossible cause
(a) Stall speed low in D and R positions

Engine output may be insufficient

Stator one±way clutch is operating properly

HINT: If more than 600 rpm below the specified value, the torque
converter clutch could be faulty.
(b) Stall speed high in D position

Line pressure too low

Forward clutch slipping

No.2 one±way clutch not operating properly

O/D clutch slipping
(c) Stall speed high in R position

Line pressure too low

Direct clutch slipping

1st & reverse brake slipping

O/D clutch slipping
(d) Stall speed high in D and R positions

Line pressure too low

Improper fluid level

O/D one±way clutch not operating properly

DI±142
± DIAGNOSTICSAUTOMATIC TRANSAXLE
(b) Measure the time lag.
When the shift lever is shifted while the engine is idling, there will be a certain time lapse or lag before
the shock can be felt. This is used for checking the condition of the O/D direct clutch, forward clutch,
and 1st & reverse brake.
NOTICE:

Do the test at normal operating fluid temperature 50 ± 80 °C (122 ± 176 °F).

Be sure to allow 1 minute interval between tests.

Take 3 measurements and take the average value.
(1) Connect an OBD II scan tool or hand±held tester to DLC3.
(2) Fully apply the parking brake.
(3) Start the engine and check idle speed.
Idle speed: 700 ± 50 rpm (In N position and air conditioning OFF)
(4) Shift the shift lever from N to D position. Using a stop watch, measure the time from when the
lever is shifted until the shock is felt.
Time lag: N " D Less than 1.2 seconds
(5) In the same manner, measure the time lag for N " R.
Time lag: N " R Less than 1.5 seconds
Evaluation (If N " D time or N " R time lag is longer than the specified):
ProblemPossible cause
N " D time lag is longer

Line pressure too low

Forward clutch worn

O/D one±way clutch not operating
N " R time lag is longer

Line pressure too low

Direct clutch worn

1st & reverse brake worn

O/D one±way clutch not operating properly

7. HYDRAULIC TEST
Measure the line pressure.
NOTICE:

Do the test at normal operation fluid temperature 50 ± 80 °C (122 ± 176 °F).

The line pressure test should always be carried out in pairs. One technician should observe
the conditions of wheels or wheel stoppers outside the vehicle while the other is doing the test.

Be careful to prevent SST's hose from interfering with the exhaust pipe.
(1) Warm up the ATF.
(2) Remove the test plug on the transaxle case front left side and connect SST.
(See Pub. No. RM654U on page AX±17 for the location to connect SST)
SST 09992±00095 (09992±00231, 09992±00271)
(3) Fully apply the parking brake and chock the 4 wheels.
(4) Connect an OBD II scan tool or hand±held tester to DLC3.
(5) Start the engine and check idling speed.
(6) Keep your left foot pressing firmly on the brake pedal and shift into D position.
(7) Measure the line pressure when the engine is idling.
(8) Depress the accelerator pedal all the way down. Quickly read the highest line pressure when
engine speed reaches stall speed.
(9) In the same manner, do the test in R position.
Specified line pressure:
ConditionD position kPa (kgf/cm2, psi)R position kPa (kgf/cm2, psi)
Idling362 ± 422 (3.7 ± 4.3, 53 ± 61)618 ± 794 (6.3 ± 8.1, 90 ± 115)
Stall735 ± 862 (7.5 ± 8.8, 107 ± 125)1,373 ± 1,608 (14.0 ± 16.4, 199 ± 233)
If the measured pressure is not up to the specified value, recheck the throttle cable adjustment and retest.
Evaluation:
ProblemPossible cause
If the measured values at all positions are higher

Throttle cable out of adjustment

Throttle valve defective

Regulator valve defective
If the measured values at all positions are lower

Throttle cable out of adjustment

Throttle valve defective

Regulator valve defective

Oil pump defective

O/D direct clutch defective
If pressure is low in the D position only
D position circuit fluid leakage

Forward clutch defective
If pressure is low in the R position only

R position circuit fluid leakage

Direct clutch defective

1st & reverse brake defective

8. MANUAL SHIFTING TEST
HINT:
By 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 to the
table below.
While driving, shift through the L, 2 and D positions.
Check that the gear change corresponds to the shift posi-
tion.
Shift PositionGear Position
DO/D
23rd
L1st
RReverse
PPawl Lock
HINT:
If the L, 2 and D gear positions are difficult to distinguish, do the
above test.
If any abnormality is found in the above test, the problem is in
the transaxle itself.
(c) Connect the solenoid wire.
(d) Clear out the DTC (See page DI±133).
