Hello

Welcome to JA!

 

Code P1740-Torque converter clutch did not lock up when the PCM sent the command. Enabling conditions: No engine or transmissions codes are present, vehicle speed was under 70 MPH, TPS was under 33% open. When the PCM commanded the torque converter to lock, no change was detected in engine speed. Blocking action: This code can block the following monitors: none.

Testing: Check torque converter solenoid for proper operation.

P1740 TCC O/D SOL PERFORMANCE

Theory of Operation
The Torque Converter Clutch (TCC) Solenoid is used to engage the TCC which improves fuel economy.

When Monitored
The Torque Convector Clutch (TCC) and Overdrive Clutch (OD) will be tested each 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 to engage
TCC or OD. This indicates a malfunctioning torque convector 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
* TCC SOLENOID
* TORQUE CONVERTER
