Thanks for the replies guys! (Hey it rhymes!) Took the tranny the rest of the way apart and the only thing I found was the 1st gear syncro had been slipping on the three notches on the back side where it locks onto the gear that is moved by the shifter fork.  I'm not sure why the 1st gear syncro would cause the jerking in second and reverse or why the noise in neutral. That's the only thing that's got me stumped. The noise in neutral was only with the clutch ?engaged? (not pushing it) so I don't think it could be the pilot bearing as the shaft and flywheel would be turning together then. The input bearing looks and feels fine/smooth. I would like to order a new syncro and put it back together but am afraid the problem may not be entirely gone.
