The clutch packs and hubs are much smaller then say a turbo400 tranny.There isnt much you can do about it and even though you can add a couple more clutches and frictions,you just cant get it to hold a ton of power.So dont expect to see any 7 sec. Z's or G's running on a "built" stock auto trans

Not sure if this has happened to anybody else?? Or if its just coincedence.

My tranny went right after I did tranny flush. The Infiniti tech told me same exact thing happened to another G35s with SC right after this tranny flush.
