Again All - these failures are a very small number we have no idea how far reaching the failures are on all GT-R's so far. One year from now we'll have a far better idea of how much of a problem this is for the entire GT-R fleet.

The internals of the actual transmission are the SAME AS A CONVENTIONAL MANUAL. It is electronically controlled internally, it has the clutchs integrated into it and the rear diff, that's why it's so expensive.
There are three different physical types of transmissions installed in passenger cars these days.
1. Manual
2. Automatic
3. CVT
The trans in the GT-R doesn't have clutch packs and it's not a CVT...so there's only one option left.
If you don't believe me...I don't know what to tell you...but the trans in the GT-R is NOT an automatic.

Looks nothing like an auto/manual...no planatary gear sets. Re-build of this trans shouldn't technically be more expensive since the gears that are failing are just simple gears like a manual. There's no valve body to clean out, or anything to really adjust. That's assuming the electronic parts are easily removable an don't need to be replaced if removed...

I'm not sure
The local guy that ran a 11.69 started a thread on how he ran his time and asked others to try it out to get some consistency. I think he's going back Wednesday to try it out, he's trying to get another local GT-R owner to go with him.

The same reason it costs over $300 for an oil change and new air filter on a Mercedes-Benz at a dealer.... 
I think the $20K quoted is for complete replacement of the transaxle + labor. Since the transaxle includes the clutch system, hydraulically actuated shift computers, rear diff and front torque controller, I could see how it can get expensive very quickly.

It amazing how the internet makes this issue look much bigger than it really is.
I have a friend that is the parts manager at one of the biggest Nissan dealers in TX and I guess he knows of one of the failures specifically. He said when they went through the ECU data the car had used LC with VDC off over 20 times in a little over a month that the owner had the car.
I consider myself an chronic abuser of my vehicles...but even I don't see a reason to need that kind of a launch over 20 times in a month. Even with a trip to the drag strip....

Martin Donnon (sp?) also has another thread regarding their new transmission fluid. You should check that one out too. Between those two threads there's a whole ton of speculation and (hopefully) accurate impressions on what's going on with these gear failures.
they needa jack the price up 5 g's and beef things up
http://en.wikipedia.org/wiki/Automatic_transmission
Main components of an AUTOMATIC transmission
1. torque converter - GR6 doesn't have one
2. planetary gearset - GR6 doesn't have it
3. Clutchpacks and bands - GR6 doesn't have them
4. Valvebody - GR doesn't have one
The main difference between an AUTOMATIC and a MANUAL is there is no physical connection between the engine and the drive wheels in a auto, it's a fluid transfer. A manual transmission has a physical connection between the engine and the drive wheels.

I've read over the posts about trans fluid in the GT-R and these are my conclusions.
The failure rate of the GR6 trans is VERY VERY low so far. That said it does seem that upgrading to a better trans fluid can significantly protect the GR6 from wear and stress. Although based on the VOIDING of the factory warranty with a fluid change, I would say only owners who really drive their cars hard or race them should worry about it.
The fact is, if you don't beat the crap out of your GT-R and the trans fails...Nissan is going to cover it for you. So for most everyday Joe GT-R owners this shouldn't even be of concern.

What do you call a transmission that has the ability to shift on its own?
A. Automatic
B. Manual
Circle the correct answer please.

oh yeah.. you also lose less boost during shifts with the seq trannies, which makes it superior to an MT
calling the sequential tranny an "automatic" is wrong. it's what the ignorant general public would call it. GTR's tranny composition is nothing that resembles an AT. It's like calling a turbo a supercharger. they're both FI but different.

For one, I'm not debating the superiority of one type of transmission vs the next, however, the GT-R's transmission has the ability to shift on its own, without any driver's input. It is an automatic transmission, as it can shift on its own, without any driver's input. It is not a manual transmission, even though it shares many of the same components.
SMG or sequential tranny of the gtr shouldn't really be called AT, but that's just me. even yahoo auto refers the gtr tranny as a manual..
