Turn ignition siwtch ON.
Check ªMANUº mode indicator light when pat-
tern select switch is pushed in to ON.
Check if A/T fluid is too hot.
Pattern select switch
Connect the Check Harness A to the ECM
(See page EG±404).
Turn igntion switcn ON.
Check voltage between terminal M of ECM connector and body ground.
Proceed to next circuit inspection shown on
matrix chart. (See page AT1±58)
Voltage
MANU7.5 ± 14 V
NORMBelow 1.5 V
Wait until the A/T fluid temp. is reduced.
The ECM uses the Normal pattern signal if the
Manual signal is not input.
Measure voltage between the terminal M of ECM
connector and body ground when the pattern se-
lect switch is set to the MANU (MANUAL) position
and NORM (NORMAL) position.
ºMANUº mode indicator light comes on and stays
on.
If the A/T fluid temp. becomes too hot, the
ªMANUº mode indicator light flashes for several
seconds and goes off. The driving mode then
automatically changes from MANU mode to the
NORM mode. AT1±86

PROBLEM SYMPTOM CONFIRMATION
Taking into consideration the results of the customer problem analysis, try to reproduce the symptoms of
the trouble. If the problem is that the transmission does not up±shift, does not down±shift, or the shift point
is too high or too low, conduct the following road test to confirm the automatic shift schedule and simulate
the problem symptoms.
ROAD TEST
NOTICE: Do the test at normal A/T fluid operating temp.
50±805C (122±1765F).
1. D POSITION TEST (NORM PATTERN)
Shift into the D position and keep the accelerator pedal
constant at the full throttle valve opening position, and check
the following points:
(a) Check up±shift operation.
Check that 1±2, 2±3 and 3±O/D up±shift takes place, at the
shift point shown in the automatic shift schedule.
(See page AT2±116)
HINT:
(1) O/D Gear Up±shift Prohibition Control.
wCoolant temp. is 605C (1405F) or less.
wIf there is a 10 km/h (6 mph) difference between the set
cruise control speed and vehicle speed.
wO/D main switch is pushed ON.
`(During O/D OFF, indicator light lights up.)
(2) O/D Gear Lock±up Prohibition Control.
wBrake pedal is depressed.
wCoolant temp. is 605C (1405F) or less.
(b) Check for shift shock and slip.
Check for shock and slip at the 1±2, 2±3, and 3±O/ D up±
shifts.
(c) Check for abnormal noise and vibration.
Run at the D position lock±up or O/D gear and check for ab-
normal noise and vibration.
HINT: The check for the cause of abnormal noise and vibra-
tion must be performed very thoroughly as it could also be
due to loss of balance in the, torque converter clutch, etc.

PRELIMINARY CHECK
1. CHECK FLUID LEVEL
HINT:
wDrive the vehicle so that the engine and transmission
are at normal operating temperature.
Fluid temp.: 70±805C (158±1765F)
wOnly use the COOL position on the dipstick as a rough
reference when the fluid is replaced or the engine does
not run.
(a) Park the vehicle on a level surface and set the parking brake.
(b) With the engine idling and the brake pedal depressed, shift
the shift lever into all positions from P to L position and return
to P position.
(c) Pull out the oil level gauge and wipe it clean.
(d) Push it back fully into the pipe.
(e) Pull it out and check that the fluid level is in the HOT position.
If the level is at the low side, add fluid.
Fluid type:
ATF TYPE T±II or Equivalent
NOTICE: Do not overfill
2. CHECK FLUID CONDITION
If the fluid smells burnt or is black, replace it.
3. REPLACE TRANSMISSION FLUID
(a) Remove the drain plug and drain the fluid.
(b) Reinstall the drain plug securely.
(c) With the engine OFF, add new fluid through the oil filler pipe.
Fluid type:
ATF TYPE T±II or Equivalent
Capacity:
Dry fill: 8.2 liters (8.7 US qts, 7.2 Imp. qts)
Drain and refill: 1.9 liters (2.0 US qts, 1.6 Imp. qts)
(d) Start the engine and shift the shift lever into all positions from
P to L position and then shift into P position.
(e) With the engine idling, check the fluid level. Add fluid up to the
COOL level on the dipstick.
(f) Check the fluid level at the normal operating temperature
70±805C (158±1765F) and add as necessary.
NOTICE: Do not overfill.
4. CHECK FLUID LEAKS
Check for leaks in the transmission.
If there are leaks, it is necessary to repair or replace O ±rings,
seal packings, oil seals, plugs or other parts. AT2±42

MECHANICAL SYSTEM TESTS
STALL TEST
The object of this test is to check the overall performance of the transmission and engine by measuring
the stall speeds in the D and R positions.
NOTICE:
wDo the test at normal operating fluid temp. 50±805C (122±1765F).
wDo not continuously run this test longer than 5 seconds.
wTo ensure safety, conduct this test in a wide, clear, level area which provides good traction.
wThe stall 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.
MEASURE STALL SPEED
(a) Chock the 4 wheels.
(b) Fully apply the parking brake.
(c) Connect a tachometer to the engine.
(d) Start the engine and check idle.
(e) Keep you foot pressed firmly on the brake pedal.
(f) Shift into the D position. Fully depress the accelerator pedal.
Quickly read the stall speed.
Stall speed:
2,600+150 rpm
(g) Do the same test in R position.
Quickly read the stall speed.
Stall speed:
2,600+150 rpm
