TROUBLE DIAGNOSES FOR SYMPTOMS
4. CHECK A/T FLUID CONDITION
1. Remove oil pan, refer to AT- 4 0 6 , "
REMOVAL" .
2. Check A/T fluid condition.
OK or NG
OK >> GO TO 5
NG >> 1. Disassemble A/T.
2. Check the following items:
–Forward clutch assembly
–Overrun clutch assembly
–Reverse clutch assembly
5. CHECK SYMPTOM
Check again.
OK or NG
OK >>INSPECTION END
NG >> 1. Perform TCM input/output signal inspection.
2. If NG, recheck TCM pin terminals for damage or loose connection with harness connector.
5. Large Shock. “N” → “R” PositionECS007R4
SYMPTOM:
There is large shock when changing from “N” to “R” position.
1. CHECK SELF-DIAGNOSTIC RESULTS
Does self-diagnosis show damage to A/T fluid temperature sensor,
line pressure solenoid valve or throttle position sensor circuit?
Ye s o r N o
Ye s > >●Check damaged circuit. Refer to the following items.
