I have the trans cooler mounted just in front of the radiator far left as it will go and the heat exchanger for the IC mounted in front of that but as far right as it will go.
I have the ATR aux. I haven't purchase a tranny coole yet, but will probably with one from B&M. The ATR is centered. WES, with the B&M infront of the ATR unit, have you notice any effects to either engine radiator or the ATR aux?
