It's obvious that the transmission is the weakest link in the almighty GT-R. With this in mind, we're already seeing <3yr old 2009's go for under $100k, and I expect them to drop down to sub $80k very early next year unless Nissan start issuing extended warranties to cover the higher frequency faults like this.
I wouldn't go so far as to say Nissan have been proactive in fixing the known transmission issues, but they have attempted "creative" intermediate fixes along the way, some of which have introduced new issues. For example, the very original 2007 models had the worst tranny issues with a shortened output shaft which resulted in stripping pinion gears.. The shaft was then lengthened and secured with cir-clips. Further down the line, the cir-clips have been found prone to fail as we have seen in the US, even in the latest 2012 models. The gear select solenoid/pistons and pressure sensor failures have been known to fail in all models across the board. In the 2012, Nissan have applied a strengthened shift fork. Some have said this is a great idea, but GT-R tranny builders in the US have commented that the fork will be more susceptable to shear forces as its more rigid and the flexibility is heavily reduced. Only time will tell...
What concerns me is that these failures are just as likely to happen in modded GT-R's as they are in stock.
There's some interesting reading here (http://www.nagtroc.o...ion-drivetrain/) as well as a Transmission Failure Registry.
In my honest oppinion, I think you would have to be mighty unlucky to have a transmission failure in a stock GT-R unless you launched it 10 times every day. However all things aside, with all the negative press covered in a multitude of forums around the world, the crappy little 3yr non-extendable Nissan warranty has to be questioned in terms of "resale", especially when the US gets 5yrs.
