As some added info, now that I've got a car with an oil temperature gauge I can see how things work a little better.
I also noticed that since I had my cooling fans programmed to be on all the time when the car is at low speeds, not only does my coolant temp never go above 194, but my oil temp now is much more stable too. I saw the oil temp hit 221F when stuck in traffic before I got the fans redone, but now since getting them done, the oil doesn't go much above 205 when stuck in traffic. I took a highway trip yesterday and my coolant temp was 189-190 at 70mph (in 70F weather) and my oil was in the 205-207 range most of the time. Tranny temps were mostly in the 170-180F range by the way.
