I have a 2004 Nissan Xterra with the non-supercharged 3.3L V6. Am wondering which transmission cooler line to the radiator is the inlet and which is the return relative to the driver/passenger side. Thank you.
In my experience, the one on the drivers side of the rad on the bottom is the inlet.
Are you looking to add an in line filter?

Thank you for your responce! I am in the process of installing a tranny cooler. It has been too hot outside for the fluids to cool for me to feel by hand which is the cooler line/return line. My guess is the same as what your saying, but don't want to take any un-needed risks.
