I'd get a used tranny from a wrecked 03/04 GT. Others are looking into beefing those gearboxes even further but so far no one has done it that we know of. Current members here are making inquiries from high-performance tranny builders and it probably can be done...just bring lots of cash
Also on your current engine you need to keep the boost under 6-7 lbs. boost or it will go Kaboom also. They will not handle the kind of power the GT is making unless highly modified.
