Sounds Great, Fish.... I've seen your posts before, Where are you in NY? I'm in Westchester County. Who is your Dealer?

HappyG

I live in Queens, NY, bordering Long Island. The dealer I went to for this service is about 6 miles away from me in Long Island.

There are still lots of snow on the road, I don't have a chance to test if the transmission still lag on dry road. Based just on my driving so far, pretty good.

Which one? Manhasset or Massapequa? I'm also in Queens and I'll try to get the reflash during the 1000-mile check up.

I'd like to know where also. I bought mine at Legacy Infiniti in Lynbrook, NY, but I have it serviced at Salerno Duane Infiniti in Denville, NJ.

HappyG

We were having problem with rough shifts and lag, not rev matching.

Here's a TSB listing for G37's, but it doesn't list any updates since August 2010

Infiniti G37 Technical Support Bullitins

It does show a TSB for harsh shifts from 2009 though.
Maybe someone could contact the owner of the above website to see if they can track down and post the new ITB10-075.

After driving for 500 miles after the flash, my car is smooth with transmission but drives like a tank. So heavy. Any idea what's going on?

elaborate a bit more?

The car drives heavy. The acceleration is taking more effort to press down and for the car to take speed. Pretty much every car from the start at lights get ahead of me even if I'm pressing the accelerator down. Its just the ups and Downs with this car I guess

Are you driving in snow mode?

MaluG37

If I'm casually driving around town I get the same feeling without the flash. But if I press the accelerator any further then the car pushes hard. My guess is that the smoother transmission with the latest flash might hold gears a little longer (providing less gear hunting and fewer downshifts) which gives a sense of slower acceleration. I'd like the trans to be smooth and fuel efficient in D and fast and aggressive in DS. But I wouldn't want the car to be slow in D just smooth.

No snow mode. I have rwd

I have to agreed that TSB is not a recall and may not be suitable for every car, you should take the car back and see what the dealer say.
