Question:

when you identify the return line for the transmission cooler are you referring to return to the transmission or return to the radiator

When the lines on a transmission cooler like part # D13503 are referred to the inlet line is from the radiator output. The output line is then connected to the transmission.

This is because the factory transmission cooler is surrounded by coolant and will be a little cooler when going into the aftermarket cooler like part # D13503.

I have attached a drawing that shows how the coolant lines are run when using an aftermarket cooler.
