From the factory, a pressure bypass was fit so that fluid can still cycle properly should a problem occur in the lines or stock cooler. Running the higher pressures induced by the ATS accumulator and valve body modifications will allow this bypass to run all the time, which will keep some of the fluid from being cooled and filtered properly. For these reasons, the bypass needed to go.

ATS supplied us with an external thermostatically controlled, fan-forced transmission fluid cooler. Trans temps can get downright ugly while towing or off-road driving and the heat is a transmission killer. Utilizing the extra deep ATS diesel transmission pan, coupled with ATS's external transmission cooling system, will ensure we have a foolproof way of beating the heat.
