Theory of Operation
The Torque Converter Clutch (TCC) solenoid is used to engage the TCC which improves fuel economy.
When Monitored:
Continuously with the ignition on.
Set Condition:
This DTC will set if the Torque Convertor Clutch (TCC) can not achieve the desired engine RPM drop when
the TCC Solenoid is near the maximum duty cycle after three consecutive test failures.
Possible Causes
TRANSMISSION FLUID LEVEL LOW OR CONTAMINATED
WORN OR DAMAGED REACTION SHAFT, INPUT SHAFT OR INPUT SHAFT SEALS
BLOCKED OR LEAK IN THE TCC HYDRAULIC CIRCUIT IN THE VALVE BODY
TORQUE CONVERTER CLUTCH SOLENOID
TORQUE CONVERTER
Always perform the Pre-Diagnostic Troubleshooting procedure before proceeding. (Refer to 21 - TRANSMIS-
SION/TRANSAXLE/AUTOMATIC - 48RE - STANDARD PROCEDURE)
1.CHECK IF THERE ANY ENGINE DTCS PRESENT
Ignition on, engine not running.
With the scan tool, read Engine DTCs.
Is the DTC P0743 also present?
Ye s>>
Refer to the Transmission category and perform the appropriate symptom(s). (Refer to 21 - TRANS-
MISSION/TRANSAXLE/AUTOMATIC - 48RE - DIAGNOSIS AND TESTING)
No>>
Go To 2
2.CHECK TRANSMISSION FLUID LEVEL
Check the transmission fluid level.
Is the Transmission fluid level low?
Ye s>>
Inspect the transmission, cooler, and lines for leakage and repair as necessary. With the scan tool read
and record the Freeze Frame data for the reported DTC. Erase DTCs and test drive the vehicle to the
conditions in which the DTC originally set. Recheck for DTCs. If the DTC resets, follow the “No” path in
this test procedure and proceed to the next step.
If the DTC does not reset, test is complete, perform RE TRANSMISSION VERIFICATION TEST VER -
1 (GAS). (Refer to 21 - TRANSMISSION/TRANSAXLE/AUTOMATIC - 48RE - STANDARD PROCE-
DURE)
No>>
Go To 3
3.CHECK TRANSMISSION FLUID
Check the transmission fluid for contamination or a burnt condition.
Is the Transmission fluidcontaminated or burnt?
Ye s>>
Remove the valve body and inspect the components related to the Torque Converter Clutch. (Refer to
21 - TRANSMISSION/TRANSAXLE/AUTOMATIC - 48RE/VALVE BODY - REMOVAL) Check the valves
for sticking or binding in its bore, internal valve body leakage, or the TCChydraulic circuits plugged with
debris. Repair as necessary. If no problems are found in the Valve Body, replace the Torque Convertor.
(Refer to 21 - TRANSMISSION/TRANSAXLE/AUTOMATIC - 48RE/TORQUE CONVERTER-
REMOVAL)
Perform RE TRANSMISSION VERIFICATION TEST VER - 1 (GAS). (Refer to 21 - TRANSMISSION/
