So the transmission on my tuck as of recently has been getting hot. Got that bad boy up to 260 F up Cajon pass and had to shut her down. So me and the boys whipped up this cooler setup to help mend the issue. So the setup follows; removed the factory front cooler, bypassed the heat exchanger, removed the metal lines, mounted one 8"x 11" cooler and another 11"X11" with an electric fan back to the pan on the underside of the driver cab while utilizing -8AN lines throughout the system. Trans is still in the 190-200 range on my in cabin ISSPRO gauge (temp probe mounted in MAGtech deep pan). Still really want to get the temps lower so I'm probably going to to ditch the 8"X11" and install another 11"X11" with another fan as well. Thanks to zdub45 at #gandjaircraft for getting me a killer deal on the cores and lines. Thanks to chadclowdus & t.j.t.battles for giving me a hand. #cummins #48re #racetowtruck
