I re-read my wording in my question and I should have been more clear.

Alright- at the risk of sounding stupid- I assume the top on the trans stays on the top at the radiator and the bottom on the bottom?

I was always taught to enter an oil cooler at the bottom and exit at the top.

Don't know if it really matters.
