HOW TO PERFORM TROUBLE DIAGNOSES FOR QUICK AND ACCURATE REPAIR
A good understanding of the malfunction conditions can make troubleshooting faster and more accurate.
In general, each customer feels differently about a malfunction. It is important to fully understand the symp-
toms or conditions for a customer complaint.
Make good use of the two sheets provided, “INFORMATION FROM CUSTOMER” and “DIAGNOSTIC
WORKSHEET”, to perform the best troubleshooting possible.
CHECK IN
LISTEN TO CUSTOMER COMPLAINTS AND FILL OUT
“INFORMATION FROM CUSTOMER”, AT-23.
Check for any Service Bulletins.
F
Refer to FAIL-SAFE Service Notice or Precautions, AT-5.
CHECK A/T FLUID LEVEL AND CONDITION. IF NG, PLACE
CHECK ON THE DIAGNOSTIC WORKSHEET, AT-24.
F
Refer to A/T Fluid Check, AT-27.
PERFORM STALL TEST AND LINE PRESSURE TEST.
F
Refer to Stall Test and Line Pressure Test, AT-27, AT-30.
PERFORM ROAD TEST WITH SELF-DIAGNOSIS AND
PLACE CHECKS FOR NG ITEMS ON THE DIAGNOSTIC
WORKSHEET.
NG items including
self-diagnostic item
F
Follow ROAD TEST procedure, AT-32.

TROUBLE DIAGNOSIS — Introduction
AT-26
A/T Fluid Check
FLUID LEAKAGE CHECK
1. Clean area suspected of leaking. — for example, mating sur-
face of converter housing and transmission case.
2. Start engine, apply foot brake, place selector lever in “D” posi-
tion and wait a few minutes.
3. Stop engine.
4. Check for fresh leakage.
FLUID CONDITION CHECK
Fluid color
Suspected cause
Dark or black with burned odor
Wear of frictional material
Milky pink
Water contamination — Road water enter-
ing through filler tube or breather
Varnished fluid, light to dark
brown and tacky
Oxidation — Over or under filling, — Over-
heating
FLUID LEVEL CHECK
Refer to MA section (“Checking A/T Fluid”, “CHASSIS AND BODY
MAINTENANCE”).
Stall Test
STALL TEST PROCEDURE
1. Check A/T and engine fluid levels. If necessary, add.
2. Drive vehicle for approx. 10 minutes or until engine oil and ATF
reach operating temperature.
ATF operating temperature:
50 - 80°C (122 - 176°F)
3. Set parking brake and block wheels.
4. Install a tachometer where it can be seen by driver during test.
I
It is good practice to put a mark on point of specified
engine rpm on indicator.
5. Start engine, apply foot brake, and place selector lever in “D”
position.
6. Accelerate to wide open throttle gradually while applying foot
brake.
7. Quickly note the engine stall revolution and immediately
release throttle.
I
During test, never hold throttle wide open for more than 5
seconds.
Stall revolution:
2,450 - 2,700 rpm
