there is no physical way a Z auto tranny will handle 800 hp. No matter how you build it. Alo the tranny is not the biggest problem, the torque converter is. There is not enough surface are on a z to actually mount a large enough oil cooler that will handle 800 hp or a 4000 rpm stall. I think you need to get more facts from the guys building your tranny. And if you do find someone to build a auto tranny for a z that handles 800 whp please let us know. Last time i checked sound performance was not interested in working on a Z.
