I just got a new 2012 G37x last month. I've been driving it every day for a few weeks and I've not had any transmission problems at all. Do they start after a while or am I just lucky?

Before you make that move, check the BMW forums too....It seems that a number of cars with 6 or more speed Auto Trannies are griping about the hesitancy/lagging. Some more that others, but that's b/c of software develeopment as sick as that sounds. I'm NOT disagreeing with you on the G, it has been frustrating, aggravating & very disappointing. I don't want to sound like a Whiner....but I work hard all day, and when I jump into my car to commubnte home 40 miles, I want that to be invigorating NOT frustrating. Am I Right?? Still puzzling : is that one day it can very close to my 2007 G35X in it's ride and response & then change completely.

I just updated my 2009 G37 to latest engine and transmission software. It has improved the hard downshifting especially at 20 mph. Car doesn't seem to downshift at all and is really smooth. Acceleration side is fine with little smoothing on shifts.

Do you have any idea what date this latest update has? I am wondering if this is the one that has been around for a year and a half, or something that has just come out.

Just came from the dealership. They said this April Flash Update will not address the "shift hunting pause". They did however reset the idle and re-flashed the original TCU. Hoping this will give me the chance to re-teach the vehicle. (I baby'ed it for the first 2,500 miles. Maybe that was the cause.) Going to drive in DS mode ONLY for the next three months.
#185 of 231 THEY FIXED IT! New TSB: May 15 2012 ITB12-027.

I had my 2011 G37 flashed by the dealer with the
latest software just released 5/15/2012.
I am THRILLED to say they finally fixed the problems!
Two days of driving and I have tried to duplicate the problem that I've experienced frequently over the last 10 months and which I have lots of practice duplicating.
The lag/delay/hesitation is now GONE. Yeah, it's a miracle, I know!
Folks, there's a new TSB out, and it's a good one.
I recommend that everyone who experiences lag or hesitation head over to their Infiniti dealer, tell them they have shift lag and request that ITB-027 be applied. Problem FINALLY solved!

Great news about the new TSB. I've also been experiencing flaring going from 3rd to 4th and especially 4th to 5th. Anyone know if the TSB fixes this phenomenon? Thanks

Can you check the TSB number, it is missing some numbers.
May 27, 2012 (4:55 am)
Sorry, I got the number right in the subject but not in the message.
ITB12-027 is the TSB number.
