Transmission Cooler Line Routing for Installing a Supplemental Transmission Cooler on a Vehicle

Updated 06/06/2014 | Published 06/05/2014

Question:

On your video, you mentioned that the transmission cooler install to the factory return line, and the other line I assumed is the line for the transmission oil to go into the transmission cooler. My question is what do you do with the factory line that you disconnect ? Do you cap it off or what ? Thanks,

Only the return line gets disconnected from the factory cooler when installing a transmission cooler like the Derale Transmission Cooler part # D13502.

Basically you remove the return line for the factory cooler, connect the inlet or the supplemental cooler to the outlet of the factory transmission cooler, and then connect the outlet of the supplemental cooler to the return line that you previously removed for the the factory cooler.

For further clarification check out the picture I attached.
