When I changed my diff fluid I looked inside the housing and there appears to be a heat exchanger where the coolant lines enter. What I mean by closed loop is a cooling system where the coolant is circulated through a heat exchanger that is completely separate from the fluid that it is cooling. I don't know a better way to describe it and you can google "closed loop heat exchanger design." for a description and diagram.Not sure what you are saying. The coolers are external to the diff and the transmission. Would be pointless to have them inside the component you are trying to cool. Unless I am misunderstanding what you are saying.
If you look at the capacities section, you will see two listed. One for the diff and one for the diff+cooler. Same for the transmission.
