You are correct in that the problem wasn't in any way resolved in any of those years. They got the leaking seal worked out early last year and it now appears that as of the middle of last year, Ford may have solved the clutch issue by finding a new supplier of the clutch material itself. If you can get your car to fail the clutch slippage test, you can get the new clutches and it should hopefully solve your problem. My second set of clutches (from a couple years back) is getting progressively worse with the shuddering. Unfortunately it's not bad enough to fail the test and I'm now out of the "extended 100k" warranty. So the cost will be all on me when I need to replace them.
