A vehicle used for towing may sometimes benefit from an additional transmission cooler. 1 member had to put a external cooler on … I removed the bypass and the maximum transmission temperatures was 180 pulling steep hills in hot weather. I've tried two different bypass valves with this cooler and both times the transmission temperatures shot up over 200 degree rather quickly when towing with the bypass installed. If you were to put a separate bypass "air" cooler, you may be inhibiting the quick warm up provided by the coolant on cold starts. The main reason I want to install the trans cooler is so i can bypass the trans cooler inside the radiator so I can keep the heat from the trans out of the radiator so it can more efficiently cool the engine.
