When/if the $10 overdrive band starts slipping, the temps will also start climbing quickly. Just keep it out of the od detent and use it as a 3 speed until you get time to change the band. It is basically a c4 anyway. A late 80s aod should have most of the bulletins incorporated. The band usually lasts about 80,000 miles in a 4000 lb car driven by the average non-mech, so the one that is in it now will probably last a long time if the tv cable is set properly for adequate pressure and the fluid was changed as it should be. A deeper numerically higher gear helps it last longer too.
Sorry, I must beg to differ. I once owned the same vehicle as this donor car - an '88 TBird (one of the few that I've owned that I wish I still had) - and the AOD transmission never, ever gave me a lick of trouble. It had 82,000 miles on it when I bought it, and almost 17 years old with 169,000 when I had to sell it. And I took full advantage of what was in actuality a roller cam 1986 speed density Mustang engine (down rated about 10 HP because it lacked true dual exhaust)
Also had a 1981 Cougar with the same transmission, same reliability, but it had the anemic 200-whatever CI Windsor V8, so that doesn't really count
