Transmission ???\'s I have a TH350 in my Jimmy. There are two cooler lines running to the radaitor. Which one is the intake and which one is the out flow. When I bought my truck a tranny cooler had been installed and I think it is in wrong. Follow me here. Shouldn't the fluid coming from the transmission go to the radiator (top) and then out (bottom) to the tranny cooler than back to the tranny. To me this makes sense, keeping the transmission fluid cooler than running it though the tranny cooler and then through the radaitor cooler. Basically I just need to know which line is which so I can make sure they are plumbed right. Any help would be appreciated.
