Hey, AG! Sorry to bother you, but you seem to have some pretty detailed E-knowledge, and that makes you a target, of course. Question: I've been looking into transmission coolers for my E, because I'm buying a popup and will be towing about 1500-1600 lbs. When I started poking through my service manual for info, I got the impression that there are transmission fluid lines that ALREADY rout through the radiator. Am I wrong here? And if that is correct, would any additional bolt-on cooler be a waste of time(money)? Thanks for the help!
