tranny cooler

so i've read through several tranny cooler threads and still don't know which way to go. the thing i need to know is whether to run the tranny lines into the cooler first than the rad. or to the radiator then to the cooler. any help would be great. thanks in advance guys.

It's split down the line between whether or not to run it through the stock cooler in the rad as well: some do it and some don't. I ran my lines through an aftermarket hayden on my last xj and that was it. Never a hiccup from my trans.

if you are going to keep your radiator in the loop, you want to run it through the radiator first, then through the tranny cooler.....
