Well I was denied. Was told my TCM and ECM were 'current' and there were no codes found in either as well. Last trans flash was over 6 months ago. Tech said he drove another new 12 g37 with 7a/t and it felt the same. Well NO DUH since it doesn't have the update EITHER.

So, how do you guys recommend I proceed? 2011 G37xS 7A/T

What is your source for this knowledge? I was just told it does not apply to my '11 G37 xS.

There is a HUGE other thread on this forum... And the dealership. ITB12-027A it says on my receipt. Apparently the "A" extended it to the 09's.

Try calling another dealer but don't mention the first dealer. Be nice :-)

I saw that one, isn't this the newer one though?

Well, I called and spoke with the service manager and casually mentioned I had been digging around and tossed this TSB 12-027 at him. He called me back later and told me I did indeed have the most current update for my year, model type. He said if there was a newer update than I have they would be happy to try to solve my lag problems by applying it. Said they simply cannot since the system shows nothing newer.

Well damnit.

Quoted from post 1246 in the other massive thread...

Maybe the dealer is not using Consult 3+ so it's not showing any available updates for your car?

i got the same answer but they also told me my car was low on trans fluid so they added some, still shifts like poo.

Just got this done yesterday at the Englewood dealership in Englewood, NJ. The car drives much better. Its as smooth as can be, I am very satisfied, and the customer service at the dealership was top notch. I made the appointment the same day via the computer and they took care of me on the spot when I arrived. Within 30 mins I was out. I have a 2011 X. I recommend this to everyone who has the lag/hesitation problem.

Quick question for those that have had this latest TSB for the tranny done.... did you already have the 10-075a TSB from 4/15/11 performed on your vehicle and, if so, are you noticing a big improvement? Although the reports posted so far seem to be extremely positive, it's not clear how many of those getting this latest update had either only gotten the very first update performed or had never had any of the prior AT TSBs performed.

I am wondering the same thing - Has anyone had the new TSB applied who had 075 applied?
I have a 2010 G37s I purchased new in August of 2010. After purchase, I noticed the same transmission problems that everyone is describing (and noted in TSB 075 & 027).
On 3/6/2011, I had my local Infiniti dealer perform TSB10-075. This really didn't help at all.
Today I went to the same dealership for new tires (I went with the Bridgestone Potenza RE970as Pole Positions - great tires) and to have TSB12-027 performed. I took a copy of the TSB for reference.
The service adviser sold me that their computer detected the latest programming version on my ECU/TCU and that this TSB did not apply to my car.
I asked the adviser if there were any outstanding TSBs for my car and he said no.
I don't know if I need to try a different dealership or call Infiniti corporate.
TSB12-027 describes EXACTLY what is going on with my car and I want it fixed. This is frustrating.

I had both updates, and this latest one is a major improvement over the last update. The first update didn't do much at all. It smoothed out the tranny a bit, but didn't really fix the lag. The new update eliminated 90% of the lag and shifts are much faster and smoother.

ATL-G37s

I have a couple of questions:
How much time passed between the two TSBs being applied?
Did they tell you that TSB12-027 did not apply, but you convinced them to update?
How did you get them to do both TSBs?

Thanks!
