If you have an in-tank transmission oil cooler (TOC) in your radiator, I would use it because it will help put heat into the transmission faster than without one.

As far as needing a TOC Auxiliary Cooler, I personally think one isn't needed because the transmission will not make enough heat in one pass to require a cooler. But, you also want to be prepared if you have to make multiple passes which will produce enough heat to hurt the trans.
We have used our in-tank radiator TOC for years with no problem.
