im getting a trans cooler for my truck. 2012 6l80 with 3000 278mm circle d stall. should i go inline with the radiator or bypass it. i think im going inline for more fluid capacity. any thoughts or suggestions welcome.

 

I run mine just through the cooler, bypassing the radiator... Had the radiator fail and fluid mixed which equals BAD BAD BAD for clutches. Total rebuild of transmission with new clutches and cut/cleaned converter.
