    Which would be best when hooking up an external tranny cooler along with the original intank radiator cooler.

    Should I go pressure side to radiator, then to external cooler, from external cooler back to radiator, or should I go pressure side to external cooler then from external cooler back to radiator?

    Run it through the in-rad cooler first, then out into the auxilliary cooler, then back to the trans.

    Thanks Paul, that was my best guess as well. Do you know off the top which cooler line in the radiator is the pressure side and which is return side. Once again my best guess is that the top is the pressure side. /forums/images/graemlins/thinking.gif

    Are you sure about that, I just got off the phone with my tranny man and he said the top fitting on the tranny is the pressure side and the lower is the return. I am just trying to avoid crawling under the truck in the rain to follow the lines to the radiator to see which goes where.

    I just looked in my B&M Supercooler box at the sheet that came with it and it say out line is the lower and return line is the upper.

    This is for the 700R4 right? And I'm talking the line as if you were starting from the tranny, not the rad.
