transmission cooler

[expter]

I'm putting in a trans cooler inline withe the radiator and need to know which line is the feed line on the radiator. The instructions say to start the car and hold it in gear for 10 seconds and then feel the lines (hotter being feed line) but I can't tell the difference. any thoughts on running a cooler this way or should it be a stand alone unit. Thanks a lot..

all coolers should be run in front of the radiator and be stand alone. a cooler will cool 7x cooler then the radiator.

Best way to describe it without a diagram. And depending on transmission, you'll have to figure out which is out and return line. If you don't have a separate transmission cooler, get one. Hook up is simple.
Hot oil outline of transmission into bottom of radiator inlet. Top radiator outlet out into separate transmission cooler bottom inlet. Cooler top outlet back into transmission with cooler oil.
Having extra oil capacity helps keep the transmission running cooler also. Just make sure to properly fill the transmission.
