return line

[funnnyfarm]

I want to put a transmission temperature gage in , and would like to put the sender in the return line from the cooler ( I have the factory toe package) . I was going to put it in by the cooler. But witch is the return line left or right side of cooler? thanks funnnyfarm

I beleive the lower line going into the trasmission is the return. Just trace it back to the cooler.
