Trans was originally tuned by PSI who built the harness and computers for the swap.

So I called GM Performance and they tell me 200 degrees is not anything to worry about with trans temp, and that most likely what I was experiencing was the trans learning my driving habits and that different things adjust at different temperatures. Being that it was just installed few days ago. Told me adding the cooler in front of the radiator was a good idea and would just help transmission live longer. I dont know how much is true but its under warranty and there now is a case# so I should be covered.
