Trans Tune for an intermittent sticking solenoid code [SOLVED]

Thanks for the question, Gary. For a P0744 code, I’d recommend taking it to a reputable mechanic in your area. Here’s a quick rundown on code P0744: This malfunction is detected when the torque converter clutch does not lock-up as instructed by the Transmission Control Module (TCM). This is not only caused by electrical malfunction (circuits open or shorted), but also by mechanical malfunction such as control valve operation, improper solenoid valve operation, etc.

Unfortunately, Trans Tune would not help with this.
