Determining Return Line for Installing Transmission Cooler
Question:
Hello, I am looking at transmission coolers for a 2013 Ford F-150. My question is do I hook it up to the factory transmission cooler line going into the top or bottom of my radiator? I am talking about the cooler inside the radiator, I do not have a factory external transmission cooler. Thanks

We have to determine which transmission line is the one that returns back to the transmission and that is the line a supplemental cooler would need to be installed on.
In order to tell which transmission fluid line is the return line leaving the factory cooler of a vehicle like your 2013 Ford F-150 you want to start with your vehicle cold. Start it up and put it in drive and brake torque it (apply brakes and rev the engine), for about 10 seconds or so, put vehicle back in park, and turn engine off.
Now quickly go out and feel both transmission lines. The cooler of the two is the return line and the one to use for installing the # D13503.
