Well, they pulled my trans under warranty a few times for different issues. You gotta be persistent and determined. If need be, try a few different Ford dealerships. If your car isn't right it's Ford's responsibility to make it right- even if it means pulling a trans for something that appears small. It might be small now but 6 months from now, or even 2 weeks past the warranty expiration your car could die because of a little issue they should have fixed in the beginning. Stick with it & make them get it right!
