I have had that same problem with my focus. This spring im planning on getting a clutch and flywheel kit for my car and was thinking about having the tranny rebuilt while i was at it. But it sounds like you guys are saying just the clutch and a minor adjustment or two will fix it?
The 3-4 syncro is weak in the mtx 75. I just replaced all the seals,bearings and the 3-4 syncro. I think all the parts were like 300 bucks or so. Replace the shifter cables while your there too, they were a pain to do.
