If a filter can stop crud from getting back into the transmission, why wouldn't it prevent crud from getting into the cooler also?

It could, but if there's already crud in the cooler, the idea is to keep it from getting back to the tranny. If your tranny and cooler are new, it definitely wouldn't hurt to add a filter either before or after the cooler.

Okay I see your point now. When I installed my new 6.0 cooler I added the transmission filter...but it was installed after the cooler per instructions. I have always wondered why they said to install it there instead before the radiator/cooler. I thought maybe they were concerned the fluid would be too hot at that location for the filter.
