Since I’m only running 1 radiator fan can fan 2 output be set up to control a remote trans cooler relay on a 0411/ 4l80E ?
 
Yes, You'll have to modify fan On/Off temps in the calibration. I'm sure you know both outputs are controlled off ECT not trans temp.

Originally there are 3 relays that run both fans at half speed (In series) for Low Speed & then full speed (In parallel) for High Speed. But that won't stop you from doing what you want.
 
Thanks for the reply! 👍
So which way would you cool an 80 ?
Via pcm or inline temp switch/ relay?
