I have a 2011 G37 Sedan Sport,

I notice the shifting is almost like its tries to overcompensate to keep the same rpm into the next gear, such as you feel the car start to shift and then it revs up a bit more then shifts?

Also, I get a almost beeping sounds coming from the wind on my right passenger side when I am going around 80+mph, it is definitely the wind just not sure where to pinpoint it, im thinking the wind is hitting the mirror at a certain angle to create sound, thoughts?

 

Are you talking about downshift rev matching? Then yes, it is a feature on every G.

 

No im talking like 2nd to 3rd or 3rd to 4th
