Based on all of the information so far. On our local Z club 3 people have already had there tranny's replaced under warranty(350z's). They all had under 20,000 miles and there transmission's where grinding already. I have seen 2 people local with added supercharger's go through there tranny's within 6-8k miles after adding the supercharger's. If it can't handle stock power or even 400rwhp safely, how is it anywhere as strong as the Z32's?
