What is the exact size, and type, fitting that screws into the trans cooler in the radiator?

It's difficult to know just how much you don't know until you know it.
In other words... if people learn by making mistakes, by now I should know just about everything!!!

The reason why i was asking is because i want to do a transmission flush.  But my radiator does not have fittings from the trans cooler that protrude out---so there's no place to put a hose on to.  So i thought i needed some sort of barb fitting.  But i think i will just buy some 5/16" brake line from Autozone and slip a hose over it.

This also leads me to my next question in the external trans filter thread........
