Will monitor it for 2 weeks to see if it comes back again.
I had that exact same issue several weeks ago, but it's still kinda surgy in the 30-40mph range and has a rough idle. Resetting the adaptive transmission helped a bit, for awhile, but eh. I may just have to learn to live with it since no one has a tried and true solution that I've heard (and which actually completely works).
