P1740-TCC O/D SOL PERFORMANCE (GAS)
For a complete wiring diagramRefer to Section 8W
Theory of Operation
The Torque Converter Clutch (TCC) Solenoid is used to engage the TCC which improves fuel economy.
When Monitored:
The Torque Convertor Clutch (TCC) and Overdrive Clutch (OD) will be testedeach time the PCM requests
TCC engagement in 3rd gear and OD.
Set Condition:
The DTC will set if the expected RPM drop is not achieved while attempting toengage TCC or OD. This
indicates a malfunctioning torqueconvertor or overdrive clutch.
Possible Causes
ENGINE DTCS PRESENT
TRANSMISSION DTCS PRESENT
TRANSMISSION TEMPERATURE TOO COLD
OIL PAN CONTAINS EXCESSIVE DEBRIS
3-4 SHIFT SOLENOID
SHAFT OR SEAL DAMAGE
