Aftermarket Tranny cooler vs. in Radiator cooler

[75stepside]

Just trying to decide what to do... i've got a Turbo 350 w/ a B&M 10.5" converter behind my Fresh 350. When i took the engine/tranny out of the truck originally, it had an aftermarket cooler in front of the radiator. Now, my truck has AC and i'm trying to avoid the sandwich of my AC condensor, radiator and tranny cooler.

Soooooooooooo, is it such a bad idea to just hook the tranny cooling lines up to the radiator, as it is already setup for this... what are the differences between this an an aftermarket cooler?

your opinion???

thanks much!
