B&M super cooler mounting questions

I've got 2 questions about mounting my B&M Super cooler plate style trans cooler. First I have a Dodge A100. So I can place the cooler about 2ft in front of the radiator ..right behind the grill , this would give me the beat air flow (while moving)
Also I DO NOT have a cooler in the radiator !!
Back to the Super cooler plate type cooler. Will mounting the cooler with the hose ports pointed down be a problem ??? Will it cooler trap air inside , and reduce the coolers effect ? I've read this else were I'm unsure.. Tell me what you think
