Tranny cooler lines leak?

[lyndon9]

i have both of my tranny cooler lines leaking right where the rubber hose meets the metal hose. Is this a common issue with 4th gen’s?

Lines on my 12 leak there, but only when it get really cold out.
It won’t leak a drop all summer, but as soon as the temps get close to freezing in the winter, it will drop just enough to leave a damp spot on the frame.

I had it happen on mine.Replaced both lines as they come in a pair, pretty straight forward but it was a pain in the ass to route them. I had to seperate them and one went in from the top and the other from under the truck. I should have just went with my original plan of using braided hose and AN fittings as it would of been alot easier than trying to route the hardlines

Mine lesk worse with cold temps also. Rubber must shrink to the point they leak.
