I get that in my 2IS too, its super annoying.

I think its mainly because the software for the auto box suck *****. When I give it gas in slow speeds for example, it is in neutral, then pops into 2nd, then suddenly thinks maybe I want more acceleration so it drops into 1st, CLUNK, realize I am barely inching along and upshifts into 2nd, CHUG
