Nissan GT-R tranmission failure

Samurai Speed, a tuning shop the specializes in the new Nissan GT-R, recently popped open a busted GT-R transmission to see exactly how it failed. Although this particular GT-R was creating much more power than stock, the photos do confirm the chink in the GT-R’s armor. As you would expect, the damages were isolated to the first gear and gear shaft.

For 2009, Nissan released an update to its Transmission Control Unit (TCU), limiting the car’s RPMs at launch to 3,000 when the Vehicle Dynamic Control (VDC) is switched off. Prior to this update, the GT-R would rev to about 4,500 RPM. Nissan implemented the changes after a controversy was started on online forums by owners reporting that Nissan would not be covering any damages caused by launching the GT-R with the VDC off. The void to the warranty is supposedly in print in the always-thoroughly-read owner’s manual.  

The updates to the TCU are not all bad. The changes also increase the RPMs from around 2,000 to around 3,000 when launching the car with VDC on.
