I'm no tranny expert, but I did just R&R my tranny on my 95 and did a bunch of test to try to see if it was sensors or the tranny itself. I believe that the sensors tell the tranny when to shift. If your tranny shifts fine when cold, unless the sensors are malfunctioning when they get hot, (which I doubt) I'd have to believe that you need a new (used junkyard) transaxle. You should be able to find a good one for between $300 - $600 depending on the mileage. It's a lot of work but I did mine by myself in a couple of days. Pay extra to get the lowest mileage one. It will be worth it to not do it again in the near future. I am running my new used transaxle with 50% new fluid right now and in about 3 months I'll drain it and put in some transX and new fluid. When you drain a tranny you only get about half of the fluid out. Whatever you do, do not get your new tranny flushed at a shop. You are better off just replacing 1/2 of the fluid per change.
