I've got a 140,000 mile 2002 GT that is about to have the trans rebuilt and a new clutch installed next week, but it's just now starting to have some real problems, and I'm wondering if the clutch is actually going out. I had it test driven by the transmission guy almost a year ago and he said the transmission had a bad bearing and the clutch was not feeling that great. But as far as I could tell, it still drove fine, just made some noise I didn't like. Now it's starting to feel funny at low RPM's, like the engine is losing power or not able to rev good (or even like the tires are out of round or flat or something on acceleration, but when you coast in neutral there's no problem), but the issue seems to disappear as I get close to 2000 RPM, and the engine revs fine when it's in neutral. Is that a clutch issue?
