G37 7speed transmission reprogram

Someone correct me if I'm wrong, but I believe the up/down shift points are adaptive, meaning the computer saves parameters as you drive, and tries to optimize shift points to your "driving style" (which is, I'm guessing, a bunch of saved parameters for each gear transition).
So my question is, what about just clearing the "driving style" memory and letting the computer re-acquire the driving style parameters, to see if that fixes it, before changing the program itself via the TSB? On some cars, the driver can clear the memory without going into the dealer.
If, after clearing the memory and letting the computer re-acquire your driving style parameters you still have the same problem, that would be a more solid argument for changing the program itself.
Any thoughts?

Hopefully we can get some feedback on this TSB soon as I can't get to the dealer for a couple months, but it would be reassuring knowing it is indeed a positive step forward for our 7ATs.

My only other annoyance is the flare from 3->4. I'm bringing my car in for them to look at the huge bubble I have in my driver seat in a couple weeks, but don't know whether or not to bring up the tranny issue.

I just got the program installed in my car as well as few weeks ago another update but this one seems to fix the issue of gear changing from 1 to 2 smoothly but still have that scare down shift if you are going to a stop in DS mode the RPM goes buzurk and revs to 5000. Minor fixes but still issues

I had mine reflashed last week when I had my first oil change done. I didn't get it just because the update existed, but because it was pissing me off. Since the reflash it seems better but far from perfect. There are still quite a lot of clumsy gear changes but they aren't as violent or as frequent as before.

Took my G to Infiniti dealership- they test drove it and found no unusual problems. They also said that there were no TSBs for the 2010 model, but just for the 2009 model.
Does this 2010 TSB really exist or was that a TEASER?

That's the same response I got from my dealership earlier. Please post any reviews of the 7AT after the reflash and a copy of the TSB.

I brought mine in this morning, their internet service was down and as a result they couldn't do any updates, but they told me that they charge $130 to do an evaluation for any TSBs. Is this standard practice? I was expecting no charge for a TSB related service.

If the car is under warranty, it should be FREE. Take it to another dealer and/or contact Infiniti directly to report them.

i've encountered the "internet service is down" excuse from service departments. Not only from Infiniti, but from Audi, VW, and MB. It seems that's a good excuse to them when they don't feel like doing something. Although I've never heard that excuse when you go in to buy a car from the dealer. Just sayin...

I don't think there is a TSB out there for 2010s, we are already on the most recent tranny updates. I could be wrong...but that is what I think.

dirtymaf: Did "corporate" give you the TSB issue No? There seems to be a Mystery about this TSB "fix" for the 7 AT.......
On another thread, a member DaMayor from Massapequa Infiniti in Long Island, NY, posted that the TSB about the 7 AT performance just came out 2 weeks ago? DaMayor, can you help?

Those of you how have hard time getting the TSB, just go to the service department and complain about the transmission lag and hasitant and the rest should be followed by the service advisor. Two times I took my car in and all I had to say was that my transmission is lagging and revs up/down crazily. The service advisor without any questions reflashed my transmission ans ecm twice now with no charge whatsoever.
