Yes the transmission currently works that's the first rebuild done to it but the owner also done a lot of over load of hauling and burnouts on it, I don't know if it's needed for the added horses + making more reliable. It's the 4l80eYour truck should have the 9.5" rear end that is plenty strong enough.
And for the transmission, does it currently work?
4-5k for 300-350hp is pretty expensive horsepower.
Like L31MaxExpress said I want to just get everything replaced instead of fixing when broken
