[Karl Bebout]

I've run TH400 transmissions for years and have always thought that the trannies last much better if they are well cooled. In addition to a large (12"x16") finned radiator-type cooler, I also run a Derale tranny pan that has cooling tubes incorporated in the bottom of the pan that drops the temps an additional 10*-15* (advertised) I've never heard that over-cooling an automatic is a bad thing. May be wrong, again, just have never heard that.
