Transmission Flare between 3rd & 4th?

Have fun reading the thread:

G37 7speed transmission reprogram... - MyG37

There are actually 3 versions. The 1st one was released early 2009 and was not popular. Then came ITB10-075 in 2010, and recently ITB12-027. Not sure how what the code is for Nissan vehicles.

What's funny is that my '12 Z seems to have the same issues that the 2009-up G37's had. Severe engine braking during decel, severe 2>1 down shift, and flare during the 3>4 and the 4>5 upshift.

Do I have the same software as the 2009-up G37's? I would think my car has improved software. Can others that have a 7AT confirm this?

You would think that Nissan would have gotten this right after 3 years.
