Went to Estes 2 years ago with the same rig. Trans got hot soon as I left Lyons, Co. Turns out the Superchips tow mode increased torque as it should but the operator had not increased cooling. Turned the chip off and made it home in one piece. Got a new 4 core with intercooler and left the chip off. I've been told I should switch to a 26 row cooler and understand why, just not sure how much longer I will keep this beast. My brother has a 2017, same config except the engine and he is planning to sell it in a year or so. I've driven his truck and like mine better but driving a 20 year old truck does come at a price. Hubs, ball joints, water pump, sway bar bushings (which I have fought to no end). My truck has 265K on it but I've only had it for 65 of that.
