so u removed 1 tranny cooler and now it shifts fine, i knew u were overcooling the tranny. since it takes a while to warm it, u may still be overcooling it, how long is "a while"? as for your current problem, u say its the exact same setup u used to run and u didnt over heat. what have u changed since then? your tstat may be your problem but i'm not sure. maybe your stock temp gauge is wrong, or your temp sensor could be reading incorrectly, stock gauges are crap. but the temp gauge fails at the same time u do cooling work? what are the chances? i wish u luck and post results
