Frank, its not the syncro. In a tremec, on the underside of the first to second slider gear and the third to fourth slider gear, there are 3 little detents held in by springs/ c-clips. These detents are about 1/2 inch by 1/4 inch rectangles with 1/8 inch sides. When you pull it apart, I will bet you anything the detents have broken ends in the first to second gear slider. I had the exact same problem on my first tremec. I would try adjusting the clutch out to see if that helps, but I would bet money that those detents are broken. It will still shift, just a lot slower as the syncros have to slow the gear all the way down before it shifts. It should still shift without the clutch onse the gear slows. Hope I am wrong, though, good luck. scott
