Nasty_01T/A

I have a built 4l60e with a yank SS 4k stall in my Trans Am right now but I am selling it and buying a 4l80. What all do I need to change to the 4l80 before putting it in the car? My car is making 580hp right now but I am also doing more work with it soon and it'll put down more.
Thanks in advance for the help.
