There's a noticeably longer delay in catching the next gear and you can see the RPMs jump right before it goes to 5th. There aren't any clunks or anything of the sort. Aside from that, the tranny is smooth. Any idea what that could be or what I can do to fix it?

7AT??

Infiniti has a TSB to reprogram the TCU.
Nissan should be the same.
CHeck with your dealer.
