96 Dodge Ram 1500 5.2L transmission leak troubles

Does anybody know of a video on how to run molded metal transmission line. My Ram has a leak at the interior of the Quick disconnect on the upper line still after replacing the quick disconnect with a dorman part and and dealer part. Part of me thinks the end of the transmission line may be warped or I may be missing an o-ring or gasket at the end of the line. The quick disconnect does contain an o-ring inside it.

Thank You,
