I don't believe that you want a manual transmission similar to a 4T65e as that is only a 4 speed box. The one that fieroguru recommends is the one that I would use as its a 6 speed. Also know that he sells several LS4 swap parts that would make that difficult swap much easier but you would still need to remove the AFM that requires replacing the lifters, activators and cam. Good choice if you want a V8 with 303HP but IMO not an easy first time swap.
