automatic trans cooler flow direction

str12-340 said
I'm installing an A500, but I think the answer for this would apply to all Torqueflites - which port in the side of the transmission pumps trans fluid to the cooler and which is the return line. I'm installing an aftermarket trans cooler and want the pressure line to go to the fitting on top and the return line to leave the bottom of the cooler.

Thanks!

I have mine in tandem with the one on the radiator and hooked it up like this. The red is hot, red and white radiator cool, and blue is the cool return in my colorized version.
