The GTR is apparently blowing out all of its transmissions when people do a launch in "Launch Mode" with the traction control off for maximum acceleration. The problem is that the Black box in the car records the fact that you used "Launch Mode" and Nissan voids your warranty. They make you pay $20K for a new transmission. The car is advertised to run 0 - 60 in 3.5 with the Launch mode on, except by using it, you void your warranty. With Launch mode off, the car runs 0 - 60 in the mid 4s and adds a full second to its quarter mile time.
