I also think that the engine coolant should only cool the engine. But the reason that auto trans coolers are integrated into the radiator, is to bring the transmission fluid to proper operating temperature.

So if I were you, I would make a 200°F thermostat control the fans on your tranny coolers.

Sweet truck, though. It's cool that you stuck with the 5 cylinder.
