Well I have a problem and hopefully I can get a correct diagnosis. I have a 2000 Zts manual and about a week ago I was driving home from work. I was coasting down the hill in neutral and without pressing down the clutch I bumped the shifter towards 3rd grinded the gears. I thought there was a safety to prevent that. Anyways now every time I shift to 3rd there is a grinding noise. Its not hard to shift or anything, its just annoying. And seems to be some rattling coming from the clutch area. Seems to shift into 3rd without grinding around 2k rpm. Any suggestions?
