As of late, when shifting to second high in the rpm's, its been a real *****. Most of the time, not engaging, but grinding. It happens almost every time now. If I pull real hard down when shifting, and hold it, it engages, but still grinds a tad. its just started doing this recently. Could it have something to do with my 2nd gear synchos? I was thinking about changing to GM synchomesh, and see if that helps. What do you guys think?
