We have about 1700 miles on ours now and the tranny has been smooth and idiosyncrency free since we drove it off the lot.
The only change we have noted is that the car is shifting at a higher rpm than when new, around 3000 rpm with modest throttle and in sport mode it's got very firm and decisive upshifting as well as down shifting. I am assuming that this the adaptive programming learning how we drive.
The mileage increased from around 29 mpg to 34ish mpg and is hanging there. This is in suburban around town driving.
