Hey all. Since the arrival of cold weather in Colorado it seems that one of my transmission cooler lines is leaking right at the spot the rubber hose is crimped to the metal line near the trans fluid cooler itself (the part that is attached to the radiator). Searching these threads I haven't been able to find one that goes through that procedure. My truck is a 2007 full size 4.4 with the Jag engine and 6 speed transmission. Who else has had to replace these lines? I noticed this first during a cold spell a couple of months ago and kept on eye on it, but then when it warmed up for a while it quit leaking, so I'm assuming it leaks once it gets below 30 degrees or so. I am going to do a transmission fluid service this spring so that will be a good time to replace this line or lines. How difficult is it to replace? Do I have to remove other parts to get to it? I'm not sure how the quick connections to the cooler work. It's the one that connects to the top of the cooler that is leaking. Can anyone give some tips or advice? Thanks in advance!
