Who has a good transmission pan that has cooling fins in it??

 

Derale does, I believe. An external cooler would probably be a whole lot more effective though.

 

Other than looking different, the finned/tubed pan won't do very
much for you.

 

i really liked the derale pan i just on her car, more capacity, and large cooling fins

a tranny cooler is definately better without a doubt, but it's nice to have some added capacity and an easy drain plug

plus it's supposed to do a good job cooling too, but doubt it will aid that much when stuck in traffic, since it wont get air flow.

downside to an external tranny cooler is chances for the lines to leak or get holes in them, had that happen a few times.
