I tried to look up which line is which but wasn't able to find anything helpful but I do have an easy way to figure it out. The most reliable method for determining the return line from a factory transmission cooler to install a supplemental cooler is to start your truck when cold and put it in drive for 10 seconds, put the vehicle back in park and then shut the engine off. Now feel both transmission lines, the one that is cooler is the return line and the one to use.
