FWIW, I just got rid of a tube&fin cooler and replaced it with a stacked plate cooler (B&M Supercooler). I'm running a 3000 stall TC, which heats up pretty good, but the difference was being scared of stopping at a red light vs. wondering if the Tranny Temp gauge was still working because the needle wasnt moving above 140. They cost a little bit more, but the performance of a stacked plate cooler is significantly better.
