Hi Heart Rod, if you don't mind I have some questions for you as I am doing almost the exact same project but mine is not as pretty! I have my 2011 5.3 engine, with original 6L80 trans, and driveshaft in. I had my computer for the engine re-flashed but not the transmission yet. I had my wiring harness done by 150tunes.com and everything is put together but it still won’t run right!

Have you started yours yet and if so, can you tell me what you had done to your PCM so I can compare? Also, do you know if you have to have the transmission computer re-flashed as well for it to talk right? I tried to drive mine on Saturday but it takes a while for the transmission to spool up (that's what it feels like) and then go. If the RPM's are not up, the trans doesn't work. Then it felt like it went into limp mode. Any help you can give would be much appreciated as I am very frustrated at this point!
