No problem, I was just making sure you wanted to continue with service P0740 sets when the PCM detected the engine speed was not within 60 rpm of ISS speed with the TP angle less than 30 degrees. This can be caused by many things such as dirty transmission fluid, worn clutches inside transmission, torque converter, or torque converter clutch solenoid. If vehicle seems to run fine I would just drive it as is otherwise repair could get expensive. The solenoid assembly is on the outside of transmission and is about a hour labor and $250 for part so round $350 total to have replaced at a shop. Here is info from manual related to code so you can see what a shop would do to diagnose and what possible problems could be. I'm sure answer isn't quite as simple as you were hoping, please do not leave me a negative ratings due to the news. Let me know if you have more questions, thanks.
