NOTICE:
Perform the test at normal operating ATF temperature 50 ± 80 °C (122 ± 176 °F).
(a) D position test
Shift into the D position and fully depress the accelerator pedal and and check the following points:
(1) Check up±shift operation.
1 " 2, 2 " 3 and 3 " O/D up±shifts take place, at the shift point shown in the automatic shift
schedule (See Pub. No. RM654U on page SS±54).
HINT:

O/D Gear Up±shift Prohibition Control (1. Coolant temp. is 50 °C (122 °F) or less. 2. If there is a 10
km/h (6 mph) difference between the set cruise control speed and vehicle speed.)

O/D Gear Lock±up Prohibition Control (1. Brake pedal is depressed. 2. Coolant temp. is 50 °C
(122 °F) or less.)
(2) Check for shift shock and slip.
Check for shock and slip at the 1 " 2, 2 " 3 and 3 " O/D up±shifts.
(3) Check for abnormal noises and vibration.
Run at the D position lock±up or O/D gear and check for abnormal noises and vibration.
HINT:
The check for the cause of abnormal noises and vibration must be done very thoroughly as it could also be
due to loss of balance in the differential or torque converter clutch, etc.
(4) Check kick±down operation.
While running in the D position, 2nd, 3rd and O/D gears, check to see that the possible kick±down
vehicle speed limits for 2 " 1, 3 " 2 and O/D " 3 kick±downs conform to those indicated on
the automatic shift schedule (See Pub. No. RM654U on page SS±54).
(5) Check abnormal shock and slip at kick±down.
(6) Check the lock±up mechanism.

Drive in D position, O/D gear, at a steady speed (lock±up ON) of about 75 km/h (47 mph).

Lightly depress the accelerator pedal and check that the engine speed does not change
abruptly.
If there is a big jump in engine speed, there is no lock±up.
(b) 2 position test
Shift into the 2 position and fully depress the accelerator pedal and check the following points:
(1) Check up±shift operation.
Check to see that the 1 " 2 up±shift takes place and that the shift point conforms to the automatic
shift schedule (See Pub. No. RM654U on page SS±54).
HINT:
There is no O/D up±shift and lock±up in the 2 position.
(2) Check engine braking.
While running in the 2 position and 2nd gear, release the accelerator pedal and check the engine
braking effect.

down±shift.
(c) L position test
Shift into the 2 position and fully depress the accelerator pedal and check the following points:
(1) Check no up±shift.
While running in the L position, check that there is no up±shift to 2nd gear.
(2) Check engine braking.
While running in the L position, release the accelerator pedal and check the engine braking ef-
fect.
(3) Check for abnormal noises during acceleration and deceleration.
(d) R position test
Shift into the R position and fully depress the accelerator pedal and check for slipping.
CAUTION:
Before conducting this test ensure that the test area is free from people and obstruction.
(e) P position test
Stop the vehicle on a grade (more than 5°) and after shifting into the P position, release the parking
brake. Then, check to see that the parking lock pawl holds the vehicle in place.
5. BASIC INSPECTION
(a) Check the fluid level.
HINT:

Drive the vehicle so that the engine and transaxle are at
normal operating temperature.
Fluid temp.: 70 ± 80 °C (158 ± 176 °F)

Only use the COOL range on the dipstick as a rough refer-
ence when the fluid is replaced or the engine does not
run.
(1) Park the vehicle on a level surface and set the park-
ing brake.
(2) With the engine idling and the brake pedal de-
pressed, shift the shift lever into all positions from P
to L position and return to P position.
(3) Pull out the dipstick and wipe it clean.
(4) Push it back fully into the pipe.
(5) Pull it out and check that the fluid level is in the HOT
range.
If the level is not within the range, add new fluid.
Fluid type: ATF D±II or DEXRON®III (DEXRON®II)
NOTICE:
Do not overfill.
(b) Check the fluid condition.
If the level is not within the hot range.

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

(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

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:
