What is currently running hot? Your transmission or the engine coolant temperature?

The # D13504 is designed to cool the transmission, and wouldn't have anything to do with the vehicle's engine running hot, only the transmission. Changing the thermostat, the water pump and the radiator wouldn't have much effect on the transmission temperature. If it's the transmission running hot, is the factory transmission cooler (or the circuit through the radiator) still connected? Is the Derale cooler tapped into the return line from the factory cooler back to the transmission?

If you could elaborate a bit more on what you've got going on there, I'd be happy to assist further.
