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.
