In the process of swapping out my tranny (turned into a much bigger ordeal than anticipated) I lost track of which like goes where on the tranny. Need to know which outlet is in and which is out on the tranny itself. TIA!

why does it say 1/8" ?
they are 5/16"
so top one is not feed
hum al;ways was told that top was feed
and bottom was return
interesting

I think you might be right, I felt the lines and the one that is suppose to be return according to TCI is hot, and the other one is cool(cooler than the other one).

was the transmission warm, not just the motor? if not, the coolant was heating the tranny fluid up, not cooling it.TrcksR4ME said:
the bottom is feed and the top is return on the th400, th350 and the 700r4, they also all use the same 5/16" line.

The line coming out of the radiator was cooler than the one from the external cooler. IIRC it should be the other way around right?

1/8 refers to thread size and the line itself is 5/16.
