Anything you pour into a tranny at best masks the problem, but it's still there. It never fixes it.

never said I would reccomend covering up a problem, love how people do that crap I simply said it helped quiet and smooth mine out when i replaced the diff in alabama then right after drove it to minnesota the next day. If I had to id do the exact same thing again. BTW since march when I drove to alabama to training then back to minnesota and now drove it to oklahoma for more training since march its had some hard highway miles. Still reccomend the lucas and will add a bottle with every fluid and filter change.
