    On a 2014 Silverado with the optional KNP transmission cooler option ... does the fluid go into the cooler in front of the radiator first, and then back through the radiator? Or the other way around. Does it matter?

    I'd guess into the radiator then into the front cooler.

    Normally, auxiliary coolers are plumbed to flow through the radiator cooler first and then into the aux cooler to then go back to the tranny, as per the image posted above.
