Thread: adding a trans cooler

    adding a trans cooler

    So I am in the middle of the swap and i got a trans cooler out of a chevy pickup between 96 and 99. The problem is on my truck there are 2 5/16 lines to my cooler in the radiator and on the cooler i have some of the factory line to mate them to but are 3/8. Has anyone else run into this? I would really like to use this cooler it fits and bolts to the radiator support like it was meant to be there

    Use reducer fittings, they should be readily available from your local parts store. Or just run dash line and AN fitting's

    i was able to get the original fittings out of the cooler so i can find fittings with barbed ends to run hoses off the cooler

    i have a 95 4l60e that has 5/16 lines from trans to radiator. The cooler I think they started putting in in like 96 maybe but I know 97 definitely had then and newer. When I went to mount it the holes were already there for the bracket there was no drilling required.
