I have a 2001 f150 5.4 7700 with the 4r100 transmission. I just replaced all the tranny lines on the truck due to rot, but I need help with the quick disconnect setup at the auxillary cooler itself. I thought I had them attached good but just blew a line off on my way home from work. so if any can please explain how the quick disconnects are suppose to go back together? Is there a special tool? or did I make a big mistake by not replacing them are they a one time use type deal? hopefully I didnt scrap the tranny that is yet to be determined. thanks for any help
