Just curious but how stiffly/notchy/hard shifting are your cars? Mine has only 4120 miles on it so I'm wondering how much it will break in and smooth out over time. I can't remember if my 89 5L LX shifted this hard through every gear when I first bought it. My 04 GT feels like a truck shifting in every gear. Would changing the trans fluid to something else smooth it out any or do I just have to suck it up and put the miles on it?
