alright, I got it running, imported the GTP transmission files to my Alero PCM, and we're off and running.

All I have to say is.....when I was at 10psi with the stock 4t45, it felt like the trans was on the ragged edge.

With the stock 4t65 in there, at 12+ psi, the trans is acting like "Is that all ya got?"

Needless to say, I am VERY pleased with the outcome. I'm not too keen on the factory 4t65 settings for downshift at part throttle, but I still have some tweaking to do and all will be perfect.
