Just because u have efi live don't mean you need a transmission. Obviously depending on what your doing. I have efi stock-120hp mainly stock transmission internals besides PPE triple lok billet tq converter, transgo shift kit, PPE trans cooler and I run a ppe deep vented trans pan for extra cooling and fluids. And it handles my 120 hp tune no problem And then if you wanted the stage 5 ppe build kit is about 14-1500. You could do that with any company I just like ppe.
