Hello, I would like to know on my Early99 F350 7.3L with the automatic transmission, does transmission fluid flow through the transmission oil cooler constantly? Or does the fluid only go to the cooler at a certain temperature? I have a transmission temperature gauge and I am in the process of adding a transmission fluid cooler. I was driving today the transmission temperature was at about 180*, I felt the transmission lines running to the radiator and neither of them was warm. I am wondering if I don't have any fluid flowing through the cooler or if it is normal until the transmission reaches a specific temperature.
Thanks to all who reply.
