How do you guys do it?

I ran mine thru the radiator first and then the cooler. My logic was that the radiator would be hot. Cool down from there. Seems like once apon a time I read the the transmission fluid has to have some heat in it to work right. But don't quote me on that.
Junk yard 1988 Chrysler min-vans are a good place to get coolers. Don't want to put any non Mopar parts on my car.:nike:
