I own a 2011 G37 Vert which I purchased in August 2011. I took my car in for service 2 weeks ago (7500 mi. service/actual mi. 3,100) with Service Bulletins for AT and phone sound quality in hand. I was experiencing the SB stated issues with both. When I picked up my car, the dealer fixed the phone problem but swore that my car did not need the AT update. Although I have been very happy with this dealer, I still question their assessment. Any tips on how to confirm my car needs/does not need the update? Thanks

I guess no one reads here. We are talking about foot clutches, not manual versus automatic. And yes, that article proves my point:

BMWs innovation creates shift gates that are surrounded by a magnetorheologic or electrorheologic fluid. That is a complicated way of saying that the fluid would prevent any improper shift when a voltage is applied to change viscosity of the fluid, therefore physically blocking any gear but the correct gear for downshift. The technology could be used on manual transmissions with a clutch pedal or without.

BMW sees an interesting potential by creating a shift-by-wire transmission where you can shift gears with a lever without having use a clutch pedal. This would be sort of a combination of an automated SMG and a traditional manual transmission. There is no indication of when this technology might come to market at this time, but it sounds like a very good idea.

Thank goodness more cars are adding this feature all the time. If Infiniti has learned anything from the 7AT fiasco it should be to make sure a dial/switch just like that is on the next gen G.

The old foot clutch will probably never go away. If I were to again buy a manual; which is not an SMG, I would get a foot clutch. To me the added expense of an SMG or whatever is called is simply not worth it.

Maybe the 7at from Infiniti made people long for a manual, however auto trannys have gotten so good that a clutch, whether computer or person controlled provides little benefit to the average person. (Except maybe in high-end exotic vehicles)

The person who wants to row their own, as opposed to the computer, will always have a market for true manual. The reason? Correct manual shifting is an art form. Something a computer does not give you the satisfaction of. Please don't use NASCAR as an example we're not talking race cars; they are irrelavent to street driving.

LOL!!! NASCAR is the ONLY major motor sport that still uses a foot clutch. To go along with the rest of the 1950's pickup truck technology that they use (it has been updated a bit very recently).

Non-NASCAR motor sport leads the way. Every innovation starts there and makes it way into road cars 1 to 10 years later. Disc brakes; multi-valve engines; higher number of gear transmissions; DSG transmissions; aerodynamics; stability and traction control; ABS; etc., etc. Often the new technology gets banned from the sport because it takes away the skill of the driver (traction control for example), but remains in road cars.

Trickle down technology is good. I would like to see every car with hid for example. However a foot clutch is different, people seem to want this as an option. The manufacturers will never get rid of what sells, period.

Got the update done today and it's definitely worth getting it done. I have only driven about 50km so far. The car feels more responsive overall and there's almost no lag. The rubberband effect is gone.

Also what I like about this update is that DS mode is aggressive compared to the last update (ITB10075), which dumbed it down completely from the original 09 programming. When I switch to DS it downshifts right away to get the rpm in the correct range. Break hard when cornering it downshifts and puts the rpm in the powerband.

So far so good.

Okay, I'll bite! Is there really a G37 Service Bulletin for phone sound quality? If so, can anyone fill me in on the details?

The 12-027a trans reprogram does not cover convertibles which is why the dealer did not do it.

I believe it covers G, FX and QX models. The M has a separate bulletin. First and foremost the phone must be on the recommended list on he Infiniti website.
The update adjustes the noise canceling/feedback so it doesn't sound garbled as much. It is however, only for vehicles w/ Nav.
In my experience, Bluetooth isn't perfect and can be temperamental, especially when it involves and iPhone or Blackberry.

I agree about iphone, I don't agree about Blackberry. At least in my case, my Blackberry interfaces perfectly with the Nav. Callers tell me voice quality is good, streaming works perfectly. There are only a few times I can remember where I had to shut the bluetooth off to get the phone to connect to the nav.

My house has a Panasonic phone system with bluetooth. My BB is synched to that, when I go to the car it syncs to the Nav as soon as the car is started.

Your phone should be on the supported list. But iphones tend to be spotty along with Android.

2011 G Sedan Re-program(12-027a)

Just a quick thanks to all those who have been contributing their experiences to this thread. It goes a long way in giving the consumer a little bit of power to excercise over the corporations that feed the mumbo jumbo to the masses (and the masses swallow it all up before thinking for themselves). On to the initial impressions.....

...My build date: 12/10
before the reprogram, I didn't have too much of an issue with some of the symptoms of the 7at, except for the lag. But once I got a 2012 loaner for 3.5 days, I knew my 2011 wasn't right.
-NOW, no lag instant accelaration which means it kicks down w/out "thinking"
-right and left turns that would make the car bog down and hesitate, no longer there. still get the normal AT type of lag, but that's just being an AT
-smoother upshifts/downshifts, feels "lighter" (like the 2012)
-tap of the gas and it's gone! feel every bit of the 269/328 power curve, more torquey (in fact, almost got away from me on a curve last night. still have to get used to the power that was missing before)
-coasts smoothly
....CONS
-no rev matching in D..good and bad, seems to coast in stop and go too much and have to use the breaks more.
-DS seems less aggressive, rev matching seems less aggressive.
-some on this thread have mentioned their cars sounding louder after the reprogram, but I am the opposite. Seems to have quieted mine down a bit.

All in all, I like it. we had to have a tradeoff of the aggression for refinement, but it is a luxury performance sedan, not just an all out sports car. But it is very much capable and fast and I'll take this update as way better than before (now very close to the 2012 AT performance). Not perfect, but damn good....

**we'll see how it feels/changes after 1000 miles or so...

Mine is definitely not performing the same as it did initially after the flash. Im regularly having to give it more pedal input to get it to "kick down" to a lower gear, especially around 40-50 mph. Once it does get enough pedal input it downshifts correctly (before it would skip down 2 or 3 gears, now it only goes down 1 and then 2 if necessary) but it still takes more throttle than it did when I initially got the flash.

Im going to try an ECU reset just to see if it goes back to the way it was. Im also wondering if I having the flash applied again would fix anything (not sure I could get the dealer to even do that anyway)
