Adding a trans cooler is a known life extender for the trans. Just because it was designed to run through the radiator doesn't mean it can't be upgraded to a better cooling system. Towing packages from most manufacturers bypass the radiator and use an external cooler.
Personally, I would leave the engine oil alone.
