I am replacing your upper transmission line on my 2008 cadillac dts . I have it until bolted from the transmission but I can not get to the rear quick disconnect. Is there and special way I can take it off. Does anyone have a video . Thanks for ur help

 

once you move plastic collar away from nut you will need a pick type to to remove spring clip. The clip can jump far and quick so be prepared. Re-install clip in nut prior to installing line.
