I've been noticing over the past couple of months that there is sometimes a slight hesitation when I manually shift gears. Mostly it occurs in the lower gears, probably going from second to third, and under light acceleration. But it has also occurred once at a higher gear, I believe fourth. I am aware of the GT-R's idiosyncrasies, particularly how it lugs along at parking lot speeds. And I'm on the second GT-R, so I think I know a thing or two about the vehicle. But the hesitation has become noticeable albeit slightly, and it doesn't occur constantly. I also just had my 24-month POS, and nothing was noted regarding this.
