Replaced the Tranny cooler lines yesterday using a kit I purchased from Advanced Auto Parts. This is a job I don't recommend doing in the cold - the old lines were tough to get off - I ended up cutting them off by shaving them (carefully) off the metal barbs. The new lines were so stiff I had to use a blowdryer to heat them up a bit to get them to push on - had to do a lot of twisting. Otherwise it wasn't too bad - I did remove the fan shroud (so I could see the lines from above) and the front bumper-cover/grill assembly to remove the front skid plate and have access to them from below. If I ever have to do this again I'm going to add a separate tranny cooler and wait until it's warmer.
