2.CHECK LINE PRESSURE
Check line pressure at idle with selector lever in “D” position. Refer
to AT-268, "
Line Pressure Test" .
OK or NG
OK >> GO TO 3.
NG >>1.Remove control valve assembly. Refer to AT- 4 1 3 ,
"Installation" .
2. Check the following items:
–Valves to control line pressure (Pressure regulator
valve, pressure modifier valve, pilot valve and pilot fil-
ter)
–Line pressure solenoid valve
3.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.
