Transmission cooler mounting vertical

Hi All

Has anyone mouted a Moroso Filtered Transmission cooler vertical?

I see it has inlet & return & the filter is not a floating one, my cocern is it not filling or cooling the trans.

My trans is a 727 reverse full manual with 4000 stall, i'm using -6 fittings with braided line & mounting it on the radiator support panel.

Also can someone tell me with is the outlet & return on the 727 box & if the pump will have enough pressure to do this.
