After lots of searching and coming up with nothing i figured i'd make this post....
Does anyone know which trans fluid line coming from the radiator is the return line???

Have a friend turn on the engine and hold it at 2000 RPM for a while. Then grap both lines and mark the cooler one as the return line.

im bypassing the cooler in the radiator completely , so i dont have to worry about that
i want the trans to be as cool as possible , our 110+ temp days are part of why
im going to be using the b&m trans cooler with the electric fan on it , and ill be using the BIG 1
Well, i've had probably 10 people answer this question for me today on AIM or on another site i posted this question on.
The problem is that half the people claim the top is the return and the other half claim the bottom line is the return...........
Is there one person who knows for sure????????????????

the best way is to pull 1 line off and have someone start the car , and 1 to watch the fluid come out
i know the cooler with the fan from b&m has a temp sending unit to turn the fan on and off , so you can keep the temp in certian range
and the added bonus of not running the trans cooler inside the radiator is your not putting added heat in your cooling system , plus you can use the manual radiator with no trans cooler , and have a little more fluid , and better coolant flow
I installed one of these on my Cav for when I towed with it, but I don't remember which line is which.. damn

best way to find out is do it
the best way to run the cooler is what i suggested
with out taking the line of on mine i couldnt tell you
I just put it inline with the bottom.

UPDATE: As suggested i started up the car and felt on the trans lines to see which one would stay the coolest. It was pretty difficult to detirmine which line was hotter / colder but it seemed as if the bottom line was the feed (hotter) and the top line was the return (colder). I'm still not really sure which is which.
I've also heard that pulling the lines then having someone start the car to see which line pumps out fluid will not work because both lines will actually be under pressure so it will be pretty hard to see which line is pumping out more.

no 1 line is pressure , and the other is return
fluid will squirt from 1 really well , the other end will just dribble out
i got this out of a service manual. the bottom line on the tranny in return.
Yeah, i probably should have posted this a couple days ago. Bottom line is the return line, thanks to Protomec for the info.

If you were to pull both lines off fluid is going to come out one (coming from the tranny), the other the fluid is going to come from the radiator. That should not be hard.
Good info here.

Actually he didn't know. He had to spent some time reading trans maps to figure it out.
