proper line cooler routing for my 4l80 want to make sure im running my lines the right way. Ive got an older style 4l80 where both fittings are right next to each other. im also using the radiator and a cooler. whats the proper routing to the radiator (high or low fitting) then to the cooler and then which fitting back to the trans?

The bottom line on the trans is the pressure line. With that being said your cooler flow should be as follows. From bottom line on the trans to the radiator. Out of the radiator to cooler. Out of cooler to top fitting on the trans. Hope this helps. Vince
