    I got a 700R4 tranny in my 86 k5 that needs a tranny cooler. Which line to the radiator is the return line to the tranny?

    It should be in at the bottom and out at the top. You can easily double check it when the engine is cold. Start the engine and touch the upper and lower lines. Within 15 seconds or so, one will start to feel warm. That's the one coming from the trans.

    That is better than my way of taking the lines loose and starting the truck and looking to see which one spits fluid out.

    "Within 15 seconds or so,"
