i second that it looks cleaner than a brand new one
the heat exchanger does nothing for cooling. it is to warm the trans faster in cold weather. hard to cool a 150* trans with a 190* coolant!
So what happens when you tow a heavy load and your transmission becomes hotter than your engine? I have seen quite a few trucks run 25* hotter without the heat exchanger on them. It has a dual function and they do help with the cooling.
