what to do to use the turbo400

[turboTURBO]

i put a 87 GN motor in a 96 camaro, im building the hell out of it...but i dont want to put a 2004r trans in it.. what would i have to do exactly to get the turbo 400 in?? i want a push button trans brake with it, and i cant find anybody that sells the push button for the 200 4r... what about wiring and all that when i switch trans, ? what all am i going to have to do if anything?

thanks and any help please...
