I have an 04 SEL Duratec that is shuddering mildly between gears -especially going into OD. Also, when sitting on a slight uphill grade with car in Drive and my foot off of the brake (car holding still), I can feel a split second sputter and the car will actually roll back during the very short sputter. Does this sound like a VSS issue, or do you think I'm experiencing the often read about 04 TC issue? I have drained the pan (lots of metal shavings on the magnet) and replaced the filter (made sure to refill with Mercon V), but it didn't help anything. Any advice would be much appreciated.
