Trans cooler mounting question

Ok gents, here's the deal.:

I'm currently having the trans in my '97 Suburban rebuilt , and am installing a new, larger auxiliary trans cooler to help the poor 4L60E live a bit longer. I bought a B&M 70266, which with a few bracket modifications will bolt in place of the factory aux cooler. The issue is the B&M says not to mount their cooler with the ports pointing downward, which is exactly how GM mounted the factory cooler. Who is correct? They are both stacked plate coolers, just the B&M is 3" taller. Is GM's mounting scheme wrong, and if so, why?

B&M says that installing it fittings down could result in a trapped air bubble in the top of the cooler. I don't know if that's really a concern, or just them covering their butts. The only way I could see that happening would be if the flow through the cooler was very slow, otherwise the vertical tube would fill to the top then the plates would fill, pushing any air out the return tube.

That said, most of the stacked plate coolers I've seen have been mounted with the fittings up.

why because b&m doesn't want to pay for trans repair.. remember the b&m might be used alone..or as you plan as an aux..
g.m.'s is not..
