TROUBLE DIAGNOSES FOR SYMPTOMS
Vehicle Does Not Creep Backward In “R” Position
ECS004V7
SYMPTOM:
Vehicle does not creep backward when selecting “R” position.
1. CHECK A/T FLUID LEVEL
Check A/T fluid level again.
OK or NG
OK >> GO TO 2.
NG >> Refill ATF.
2. CHECK LINE PRESSURE
Check line pressure at idle with selector lever in “R” position. Refer
to AT- 2 6 8 , "
Line Pressure Test" .
OK or NG
OK >> GO TO 3.
NG >> 1. Remove control valve assembly. Refer to AT- 4 1 4 ,
"Control Valve Assembly and Accumulators" .
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 (AT- 3 9 6 , "LINE PRES-
SURE SOLENOID VALVE" : Except for Euro-OBD)
3. Disassemble A/T.
4. Check the following item:
–Oil pump assembly

3. Disassemble A/T.
4. Check the following items:
–Reverse clutch assembly
–High clutch assembly
–Low & reverse brake assembly
NG in both “1” and “R” positions>>GO TO 6.
4.CHECK A/T FLUID CONDITION
1. Remove oil pan.
2. Check A/T fluid condition.
OK or NG
OK >> GO TO 5.
NG >> GO TO 6.
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.
