Think I finally figured out how to replicate it. In drive it doesn't do this. But I usually use the "sport" mode and sometimes will upshift when I feel like it. Which often means holding a gear a bit longer than the programming might care for, I'm guessing, as it doesn't always upshift right that second.
Moderate acceleration, at about 2,800rpm, going from 4th to 5th: I click "up", and I can hear the convertor unlock (rpm climbs to 3k also). Wait a second or more... finally it goes into 5th.
For mild acceleration below 2,500rpm, going from 4th to 5th, no problem. It sometimes sounds somewhat sloppy, like maybe things are shifting out of sync on this change; but I have to think I'm listening too hard. If I just put it into drive it really does its thing just fine. [I don't use drive because it has a tendancy to run unlocked on hills, so I will use S6 and drop to S5 when I think it will hunt.] If I just put it into S5 or S6, and let it do its thing, no issues detected.
5kmiles ago I dropped the pan and changed out about 7qt of WS, used Maxlife instead. That was around 78k or 80k on what I think was the original fluid. Changed filter, cleaned the pan--I thought it had little metal in the pan, fluid was a little brown but didn't seem bad compared to what I've seen online. Shifting seemed completely unchanged.
It is almost as if it's a programming problem. I swear, in S4, at times I can hear it act like it's trying to shift into 5th, only to have it... not. Something changed, and then changed back, as it's already in 4th locked.
Anyone else notice?
