auto tranny cooler lines? help
 

There are two lines going to the radiator from the tranny. Does anyone know which is the exit line and which is the return? Someone said feel which one gets hot first, but that didn't work. Thanks.

Nobody knows?

my experience with auto trannies, the one on the driver side when looking at the windshield is the return line...just my 2 cents...what are you putting in?

I already did it, but thanks. I believe I used the right side line, so that's cool. It's for a B&M tranny cooler, and you're supposed to hook it after the radiator, but before the oil return to tranny.
