I've found some info on the new Nissan GTR
the first link explains how you can't use launch control without voiding your warranty: Launch control on the GT-R voids your warranty! - FQuick.com
the second is about a guy who had the GTR for two weeks before the $20000 transmission took a crap and died
Trannies already taking craps in Nissan GTR - FQuick.com
The third shows that it has seven places for transmission replacements in the manual: transmission replacement log - GTR Forums - Nissan Skyline GT-R Community
Thats why in my opinion ill always keep to my domestics...
