Okay. More then likely the P0740 is causing the main issue. It is basically creating heat in the transmission which is causing the fluid to get hot.
I would suggest diagnosing that code first and then retest the transmission. If the other remains we can chase that but I suspect the Torque Converter clutch is the main issue.
Let me know if you have questions. Thanks
