Tranny cooler line leak

[screamindriver]

Stainless brake lines will sometimes give you the same issues with the sealing...It's recommended to use new brass fittings with the new SS lines... If you have any imperfections on the flared,sealing portion of a used fitting the stainless is quite unforgiving...And you'll need to use much more seating pressure{as in crank it down hard} to mate the parts for the first time...
