Fluid leakage in governor pressure circuit
Governor valve operation defect
Vehicle speed (Reference)Governor pressure
30 km/h (19 mph)59 - 137 kPa (0.6 - 1.4 kgf/cm2, 9 - 20 psi)
60 km/h (37 mph)186 - 365 kPa (1.9 - 2.7 kgf/cm2, 27 - 38 psi)

6. ROAD TEST
NOTICE:
Do this test at normal fluid temperature 50 - 80 °C (122 - 176 °F).
(a) D position test.
Shift into the D position and while driving with the accelerator pedal held constant at the throttle valve
fully open, check on the following points:
(1) Check to seethat the 1"2 and 2"3 up-shifts take placeand also that the shift points conform
to those shown in the automatic shift schedule (See page SS-28).
EVALUATION
ProblemPossible cause
If there is no 1 - 2 up-shift. Governor valve is defective
1 - 2 shift valve is stuck
If there is no 2 - 3 up-shift. 1 - 2 shift valve is stuck
If the shift point is defective. Throttle cable out of adjustment
Throttle valve, 1 - 2 shift valve, 2 - 3 shift valve, etc. are defective
(2) In the same way, check the shock and slip at 1 " 2 and 2 " 3 up-shifts.
EVALUATION
ProblemPossible cause
If the shock is severe.
Line pressure is too high
Accumulator is defective
Check ball is defective
(3) Run in the 3rd gear of the D position, check the abnormal noise and vibration.
HINT:
Check for the cause of abnormal noise and vibration must be made with extreme care as they could also
be due to imbalance in the drive shaft, differential, tires and torque converter clutch, etc.
(4) While running in the 3rd gear of the D position, check that the possible kick-down vehicle speed
limits for the 3 " 1 and 3 " 2 kick-down conform to those indicated in the automatic shift sched-
ule (See page SS-28).
EVALUATION
ProblemPossible cause
If the possible kick-down vehicle speed limit is defective. Throttle cable out of adjustment
Throttle valve, 1 - 2 shift valve, 2 - 3 shift valve, etc. are defective
(5) Check the abnormal shock and slip at kick-down.
(6) While running at about 60 km/h (37 mph) in the 3rd gear of the D position, release your foot from
the accelerator pedal and shift into the L position. Then check if the 2 "1 down-shift point con-
forms to that indicated in the automatic shift schedule (See page SS-28).
(b) Inspect the lock-up mechanism.
(1) Drive in the D position at a steady speed (Lock-up ON) of about 65 km/h (40 mph).
(2) Lightly depress the accelerator pedal and check that the engine speed does not change abruptly.

TORQUE CONVERTER CLUTCH
AND DRIVE PLATE
INSPECTION
1. INSPECT ONE-WAY CLUTCH
(a) Install SST in the inner race of the one-way clutch.
SST 09350-32014 (09351-32010)
(b) Install SST so that it fits in the notch of the converter clutch
hub and outer race of the one-way clutch.
SST 09350-32014 (09351-32020)
(c) With the torque converter clutch held upright, inspect the
clutch locks when turned counterclockwise, and rotates
freely and smoothly clockwise.
If necessary, clean the converter and retest the clutch. Replace
the converter clutch if the clutch still fails the test.
2. MEASURE DRIVE PLATE RUNOUT AND INSPECT
RING GEAR
Set up a dial indicator, measure the drive plate runout.
Maximum runout: 0.20 mm (0.0079 in.)
If the runout is not within the specification, replace the drive
plate. If installing a new drive plate, note the orientation of
spacers and tighten the bolts.
Torque: 88 N´m (900 kgf´cm, 65 ft´lbf)
3. MEASURE TORQUE CONVERTER CLUTCH SLEEVE
RUNOUT
Temporarily mount the torque converter clutch to the drive
plate. Set up a dial indicator, measure the torque converter
clutch sleeve runout.
Maximum runout: 0.30 mm (0.0018 in.)
If the runout is not within the specification, try to correct by reori-
enting the installation of the converter.
HINT:
Mark the position of the converter clutch to ensure the correct
installation.

(b) Check the idle speed.
(e) Check the shift linkage. (d) Check the throttle cable mark.
(f) Check the park/neutral position switch.
Check the engine and the torque converter clutch. (c) Check the fluid level and fluid condition.
STALL TEST

ROAD TEST HYDRAULIC TEST
MATRIC 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, and drive shaft 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 2 areas should be checked before proceeding with troubleshooting.
(b) Troubleshooting should begin with the simplest operation, working up in order of difficulty degree but
first determine whether the trouble lies within the engine or the transaxle.
(c) Proceed with the inspection as follows:
