Question about 2004 Chevrolet TrailBlazer
Code 0742. Says that the torque converter clutch circuit stuck on. Does this mean I should change the solenoid valve harness or connectors? Or that I should replace the solenoid valve? Or both? Where is this solenoid located on a 2004 trailblazer

This code refers to the electrical side of the torque converter not the inside workings of the converter itself. Check the electrical connector and harness for opens breaks or chaffing. Most of the times the tcc solenoid replacement will fix this issue.
