How to Identify Transmission Fluid Return Line for Installing Supplemental Cooler
Question:
I have a 2018 Toyota Tacoma with the 4cylinder 6 speed automatic transmission. It has the transmission lines running to the radiator from what I can tell. Is there a schematic that shows which is the feed and return? We bought a cooler to install enroute from etrailer and I would like confirmation on which line is which please

Expert Reply:
The surest way to find the return line in a transmission cooler system is simply to run the cold engine for about 15-seconds while it is in gear. Then immediately feel the two transmission lines. The cooler of the two is the return line that should be used for installation of a supplementary cooler such as the Derale # D13503.
