Also, no do not run the cooler before the rad. There are many threads on this. Your best bet is to run it in series with the rad, because our rad has a bit in trans cooler, as well as the ability to quickly warm it to a minimum operating temp.
trans -> rad -> aux trans cooler -> trans
Yup ^^^ And, I almost always source my various oil coolers from the salvage yard. Factory offerings are typically better quality than aftermarket (unless you get real spendy) and they are very reasonably priced at places like Pull-A-Part ($5 -$10).
Check some of the Dodge trucks and vans. They had really nice plate coolers. Doesn't have to be a Chevy part unless you are a purist and can only see one brand.
If you start doing a bunch of off-roadig, you may also wish to add a power steering cooler to the system. They can really help if you get to the point where you are twisting and turning hard while working steps.
