the line to the cooler comes out at the top of the radiator, the return comes out at the bottom and back to the transmission

Looks really good! From your description the added trans cooler seems to be before the stock radiator cooler, maybe increasing temps at times. Like the B&M plate coolers myself. Always use the stock cooler to get trans up to operating temp quickly, but have always installed auxiliary cooler after the stock cooler to decrease temps. FWIU heat is the enemy on an automatic. Am I reading wrong, or is there a reason for this choice?
