I'm actually using Amsoil ATF right now, although I should have thought it through more, since it's pretty expensive for running in the transmission for just a few weeks. Mobil-1 ATF is available here lots of places, so I'll probably switch to that in all my cars. I'm a bit surprised, but in a good way, that the problem could be resolved with a simple fluid/filter change. But that's OK by me!

And I have a new appreciation for all of my cars with maintaining more regular transmission service. The last time my wife took the minivan in, they did a transmission "flush". I'm going to be dropping the pan on that one and replacing the filter/fluid as well.
