TROUBLE DIAGNOSIS FOR SYMPTOMS
Revision: June 20062007 Versa
3. DETECT MALFUNCTIONING ITEM
1. Remove control valve assembly. Refer to AT-242, "
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
3. Disassemble A/T. Refer to AT-268, "
Disassembly" .
4. Check the following item:
–Oil pump assembly. Refer to AT-289, "Oil Pump" .
OK or NG
OK >> GO TO 4.
NG >> Repair or replace damaged parts.
4. CHECK STALL REVOLUTION
Check stall revolution with selector lever in “1” and “R” positions. Refer to AT-53, "
STALL TEST" .
OK or NG
OK >> GO TO 6.
OK in “1” position, NG in “R” position>> GO TO 5.
NG in both “1” and “R” positions>> GO TO 7.
5. DETECT MALFUNCTIONING ITEM
1. Disassemble A/T. Refer to AT-268, "
Disassembly" .
2. Check the following items:
–Low & reverse brake assembly. Refer to AT-327, "Low & Reverse Brake" .
–Reverse clutch assembly. Refer to AT-309, "Reverse Clutch" .
