Hey guys,
I currently own a C63 AMG and I'm really leaning towards a GT-R next, only thing that's holding me back is all the transmission/warranty horror stories I've been hearing about.
Since signing on to NAGTROC ive been seeing alot of threads about transmission malfunction, random CEL, car going into limp mode, etc......
So I ask you guys, are GT-R's and they're transmissions really that sensitive and problematic?

Also, If I do decide on a GT-R I'm only planing on lightly modding it with mids and cat back. (maybe suspension and wheels also) will this cause any issue with warranty?

-Thank you in advance.

You arent gonna get a straight for the questions above.

Mods do not necessarily void warranty. It's upto the dealer and Nissan HQ.

Yes the tranny is troublesome.

Many of us have had no problems, despite whipping on the vehicle HARD.  Those of us who have had problems, Nissan has dealt MOSTLY fairly.  The ones who they haven't have generally have more than one modification that COULD have been a contributing factor.  The mods you are considering will not cause a problem.  We hope you'll join us in our little community.

Anything past the cats are fine.

If you're planning on getting a catback system, no problem (or just a midpipe, either way)...

Wheels - no problem.  You should not worry about the trans warranty.

For what it's worth, I've got a 2009 with 22k+ miles with a handful of track days and probably 10 autocrosses.  No transmission issues at all.

I was a GT-R enthusiast until my super great transmission went kaput this Thursday.
Seriously, now I may want to tell you just pass a GT-R and get like a Porsche 991, a car that you don't have to worry about.
I know I can get my car fixed sooner or later anyway though the transmission issue is just BS big time.

The transmissions do appear to be the weak link with this car. My car had the transmission changed out at 7500 miles. It has almost 20K on it now and I have had no issues since, but then again it is used only as a DD. Since there have been a number of 2012 that have required a tranny swap, it appears that Nissan has done little if anything to address the GR6's weaknesses.

In my opinion, the transmission would not be that much of an issue if Nissan would train and allow the local dealerships to repair them.  However, they have elected not to do so. Doesn't seem to make a lot of economic sense to swap a $20K transmission out for a $5 seal failure. There are a number of shops that have developed the ability to repair them, and upgrade them with after market parts that address many of the GR6 weaknesses, but it is not cheap. It is however cheaper than paying out of pocket for a new tranny from Nissan after they void your warranty for any number of reasons.

The GR6 remains the Achilles heel of what is otherwise a great car. I sold my lightly modded 2009 with 18K miles to avoid this issue. If I jump back into a 2013 I plan to keep it stock. If you reflash you must assume that warranty coverage will be problematic.

I appreciate all the help guys.
Figured it would be best to get answers straight from GT-R owners.

That is good news, but I think I would rather spend the $11K for a rebuild/upgrade than another stock unit.

I was under the impression that the bugs were ridden from the tranny's for the most part. Many people don't get their warranty honored when they tune the ECU.

Transmission issues are still fairly rare, and the current state of matters allows us to repair, enhance to better than OEM shape for far less than many people thing. I don't consider this a major hurdle anymore.  Back in 2008, all it took was one trans code/issue to garbage bin the entire $20K transmission.  Those days are long gone, thankfully.

Thanks for the input.
Are the 2009 GT-R's more prone to transmission malfunction?

There may be a number of factors in play here.  One possibility is that the 2009s are in fact more prone to failure than more recent years. A second factor was the use of LC1. This created a fair amount of wheel hop and was a fairly brutal launch at 4,500 rpm. Finally the 2009s may seem to be more prone but it may just be that they have been around longer and the average 2009 car has accumulated more miles and stress than the newer models. Time will tell.

Sharif,

Do you mind going into a little more detail about repairing and enhancing the transmission (prices, ect)?   My plan was to begin my search for a 2011 or 2012 early next year and I'm really on the fence as well.  I live on the west coast and most all of the transmission guys are on the opposite side of me.

Thanks

I would not say that is the case.  09-11 GT-R's have experienced same types of issues.

Yes, I will have Ryan chime in with our preventative packag programs.  I was on the dyno the entire day, and it's almost midnight. :)
