    Tommorow I'm planning on installing a tranny cooler on my '88. Of the 2 tranny lines going into the radiator which one should I take off and run through the cooler?

    i would plumb it on the return line. less pressure, it will get cooler in the radiator (which obviously also has the water, so it stays pretty hot) then to the exteranl line to cool it off much more.

    Forgive me! How can I tell which one is the return line? Is it the bottom or top line going into my radiator or something I can check coming out the tranny?

    The info you need can be found at this page on TCI Automotive's Website. They have cooler line info on most transmissions there.

    Since this seems to be a common question, I just posted the link so others can look for their trans setup, too. /forums/images/icons/smile.gif
