after my 2nd ride yesterday i heard a new noise from my tranny (4-speed manual) and she won't shift in 3rd and 4th gear. I openend the tranny and when the clutch is pressed and i move the input shaft left-right i heard a click-click (sounds like a loosed spring). if the clutch unpressed the noise isn't there. What's that? The clutch was OK therefore i don't change.
