Cooling question - airflow - design

I do get that.

The concerns i'm setting is the factory setup, the belt fan roared all the time while the thermostat was closed, so the transmission cooler wasn't getting hot air off the radiator, but was always getting alot of airflow from the belt driven non-clutch fan.

Now it'll never get fan air flow unless the fan is on, which won't happen unless the cooling circuit of the engine is near maxed out.

The thermostat is closed, the engine radiator is not hot, but there's no fan, and the poor transmission fluid is over heating. Bad scenario.

only band-aid I can easily think up is to unnecessarily call for both fans at once, and dump air over both coolers regardless which circuit needs the cool air.
