    So how is this set up working for you now?

    I got the same kit, trying to find a way to mount it near the radiator but it seems like such a pain, you way of doing it looks much easier. After all this time is it working well being mounted there?

    Care to give some more details. I’m looking to do that. I’ve purcHased an countershaft external pump for Eaton, but no one ever did something like this. They all recommend just to cut the line.

    The problem is, you don’t have a pump in these transmissions. All they have it’s a cooler filled with coolant.

    I always use the Eaton cooler kit with bracket that bolts to bottom of aux section. Good air flow there, and not running lines all the way to the front.

    I don’t have a pump. I already know that. I’m just looking to see if anyone have the same problem, and have a fix.

    I dont think you need pump to run external air cooler. Most of truck comes from the factory with external antifreeze cooler so its almost same setup as air coller. Only thing is different air cooler uses longer hoses since its mounted somewhere else on the frame vs antifreeze cooler setup its mountetd somewhere outside on the tranny itself

    I have no idea how your going to have any type tranny cooler without a pump…the oil isn’t going to circulate by itself and most trannys without pumps done have any kind of convenient fittings to get oil in and out. Guess you can use the drain and fill plugs and hope it churns enough from driving to move it though the cooler
