It sounds like you are planning to install a supplementary transmission cooler in your 2001 Dodge Ram pickup. I have linked a couple of helpful articles to assist you. These include installation help. An install video is provided also.

The correct fluid line to use for installing a cooler like # D13503 is the return line. This is the line that routes fluid that has been cooled in the radiator back to the transmission. The supplementary cooler such as the Derale model mentioned above installs on that return line before the fluid re-enters the transmission so that it can be cooled a second time.
