Need pics of transmission line routing or a very detailed description please.

Can anyone confirm which is which? I need to know what line is return and which is feed so I can install my tranny cooler tomorrow. I want to put it downstream of the radiator IE fluid follows this path:

Transmission -> Radiator -> AUX Cooler -> Transmission

Think I found my answer in the bottom post of this link, if anyone finds this. The top line is the return line, bottom is feed. Kinda weird.

Wish I had a definitive answer for you. I just took mine off to do the transmission install, but really didn't look that the external cooler much. I think what you said is correct though. Bottom would be feed.
