Circuit/System Verification
1. Ignition ON, observe the DTC information with a
scan tool.
2. Record Freeze Frame and Failure Records.
3. Clear DTC's.
4. Operate the vehicle under the conditions observed in
the Failure Records.
5. Observe the DTC information with the scan tool.
Verify that the DTC does not set.
Circuit/System Testing
1. Using a scan tool, command shift solenoid 3 ON and
OFF. The solenoid should click when commanded.
➢ If the solenoid does not click, replace the 1-2, 2-3,
reverse shift solenoid valve assembly. Refer to
"Control Valve Body Assembly Disassemble".
2. Perform a line pressure test. Refer to "Line Pressure
Check" procedure.
3. Remove the Control valve body cover. Refer to
"Control Valve Body Cover Removal" procedure.
4. Inspect the inside of the control valve body cover for
excessive sediment. There should not be excessive
sediment.
➢ If excessive sediment is found inspect and replace
as necessary the 4-5 clutch, and the second clutch.
Refer to "4-5 Clutch Drum Assembly Assemble"
and "Second Clutch Assemble" procedures. If all
conditions test normal, test or replace the
transmission.
5. Inspect the control valve body assembly for the
following conditions. The conditions should not be
found.
– Torn or missing 1-2, 2-3, reverse shift solenoid
valve assembly O-ring seal
– Stuck U2 shift valve
Refer to "Control Valve Rear Body Disassemble".
➢ If any of the above conditions are found, repair or
replace the valve body assembly. Refer to "Control
Valve Body Replacement" procedure. If all circuits
and components test normal, replace the
transmission.
6. Verify that the control valve body has been serviced
within the past 3 months.
➢ If the control valve body has not been serviced, test
or replace the control valve body assembly. Refer
to "Control Valve Body Replacement" procedure
➢ If all circuits and components test normal, replace
the transmission.
