MATRIX CHART (a) Check the tire inflation.
Measure the line pressure and make a basic check of fluid circuit.
Check if trouble lies within automatic transaxle. If noise or vibration occurs, the possible cause could
be with the compressor, engine, drive shaft and tires, etc. Check the automatic transaxle (each clutch, brake and gear) for wear.

TROUBLESHOOTING
1. GENERAL INFORMATION
(a) Troubles occurring with the automatic transaxle can be caused by either the engine or the transaxle
itself. These two areas should be checked before proceeding with troubleshooting.
(b) Troubleshooting should begin with the simplest operation, working up in order of difficulty, but first de-
termine whether the trouble lies within the engine or transaxle.
(c) Proceed with the inspection as follows:

2. PRELIMINARY CHECK
(a) Check the fluid level.
HINT:
The vehicle mjst have been driven so that the engine and trans-
saxle are at normaloperating temperature.
ATF temperature: 70 - 80 °C (158 - 176 °F)
(1) Park the vehicle on the level surface and set the
parking brake.
(2) With the engine idling, shift the selector into each
gear from the P to L position and return to the P
position.
(3) Pull out the transaxle 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 at the low side of the hot range,
add new fluid.
Fluid type: ATF DEXRON®ll
NOTICE:
Do not overfill.
(b) Check the fluid condition.
If the fluid smells burnt or is black, replace it.
(c) Replace the ATF.
NOTICE:
Do not overfill.
(1) Using a hexagon wrench, remove the drain plug
and drain the fluid.
(2) Using a hexagon wrench, install the drain plug se-
curely.
(3) Add new fluid through the filler pipe.
Fluid type: ATF DEXRON®ll
Dry fill: 5.5 liters (5.8 US qts, 4.8 lmp.qts)
Drain and refill: 2.5 liters (2.6 US qts, 2.2 lmp.qts)

(2) Using an ohmmeter, check continuity between each
terminal shown below when the shift lever is put in
each position.
(h) Adjust the shift control cable.
(1) Remove the engine under cover.
(2) Loosen the nut on the control shaft lever.
(3) Push the control shaft lever fully toward the right
side of the vehicle.
(4) Return the lever 2 notches to the NEUTRAL posi-
tion.
(5) Set the shift lever to the N position.
(6) While holding the lever lightly toward the ºRº posi-
tion side, tighten the swivel nut.
(i) Adjust the park/neutral position switch.
If the engine will start with the shift selector in any position other
than the N or P position, adjustment is required.
(1) Loosen the park/neutral position switch bolts and
set the shift selector to the N position.
(2) Align the groove with neutral basic line.
(3) Hold the switch in the position and tighten the bolts.
Torque: 5.4 N´m (55 kgf´cm, 48 in.´lbf)
(j) Inspect the idle speed.
Idle speed:
750 ± 50 rpm (In the N position and A/C OFF)
3. MEASURE STALL TEST
The object of this test is to check the overall performance of the transaxle and the engine by measuring the
maximum engine 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 longer than 5 seconds.
(1) Check the front and rear wheels.
(2) Connect the tachometer to the engine.
(3) Fully apply the parking brake.

(4) Keep your left foot pressing firmly on the brake pedal.
(5) Start the engine.
(6) Shift it 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: 2,300 ± 200 rpm
(7) Do the same test in the R position.
Stall speed: 2,300 ± 200 rpm
EVALUATION
ProblemPossible cause
(a) Stall speed low in D and R positions. Engine output may be insufficient
Stator one-way clutch is not operating properly
(b) Stall speed high in D position.
Line pressure too low
Forward clutch slipping
No.2 one-way clutch not operating properly
(c) Stall speed high in R position.
Line pressure too low
Direct clutch slipping
1st and reverse brake slipping
(d) Stall speed high in D and R positions. Line pressure too low
Improper fluid level
4. MEASURE TIME LAG TEST
When the shift lever is shifted while the engine is idling, there will be a certain time elapse or lag before the
shock can be felt. This is used for checking the condition of the forward clutch, direct clutch and 1st and re-
verse brake.
NOTICE:
Do the test at normal operating fluid temperature 50 - 80 °C (122 - 176°F).
Make sure to allow 1 minute interval tests.
Make 3 measurements and take the average value.
(1) Fully apply the parking brake.
(2) Start the engine and check the idle speed.
Idling speed: 750 ± 50 rpm (In N position and A/C OFF)
(3) Shift the shift lever from the N to D position. Using a stop watch, measure the time it takes from
shifting the lever to the shock is felt.
Time lag: Less than 1.2 seconds
(4) In the same way, measure the time lag for N " R.
Time lag: Less than 1.5 seconds
EVALUATION (If N " D time lag are longer than than specified):
ProblemPossible cause

fect.
