When I went on my first test drive, after about a mile, I made two full throttle rolling starts from 2nd or 3rd gear in auto mode and it seemed to hesitate between shifts, almost like driving a manual shift car with a clutch. It didn't drop into the next gear harshly but it was firm. The RPMs seemed to only dip slightly so I don't think it was slipping because I'd expect them to increase.
On a more positive note, my morning commute to work seemed flawless but I kept a very light foot all the way here. I'd like to think that maybe the trans was relearning my driving style after being disconnected. If I'm still experiencing this issue by week's end, I'm going to reinspect the fluid level.
