I'm going to install one of these when I get around to it. Ill probably install the temperature probe in a T fitting before my external cooler so it doesn't restrict the flow of fluid.Thanks for the info, Todd. I figured the trans could only run cooler than stock if I quit bathing the fluid in hot engine coolant, but everybody says if you bypass you need the aftermarket cooler. You're the first to tell me you just bypassed the warming loop in the radiator tank and did not add an additional external cooler. After warranty runs out on mine, I may consider doing the same bypass-only mod. Need to get some method to digitally read trans temp before and after so I know what temps its running. Wish someone with knowledge would figure out how to get trans temp on Torque like he BDGT gives. That would be super easy.
