as far as i know all of the GM alum. trans. the top line coming out of the trans is the pressure line which goes into the top of the radiator and the bottom line is the return line coming out of the bottom of the rad. going back to the lower fitting in the trans. the external cooler would go into the bottom line. i have put them in the upper line and didnt see a dif. that i could tell. but i guess if they say put it there then you should.
