Transmission return line

Im confused .

I need to know which one is the cool or return line for the transmission ?
I've read that the return line is the top one , but the top one is hotter then the bottom line.


By the way my radiator is aluminum and my car is a T-bird 4.6 made in Aug 97

Thanks

take both lines off and start the car. Whichever one is spewing fluid out is the hot line. The other will be the cold line.

The top line from the transmission is the bottom line of the radiator.

how come on some mustangs, the trans return line in opposite (comming from TOP of rad)?

I got to thinking and thought that if you forced the atf UP against gravity, it would purge air from it all the time....but that is the only real thing I could think of as to why they did that in the SN95's.
