I was sure I saw something similar to this on an earlier thread, now I can't find it. Yesterday as I was going uphill, gearing from 3rd to 4th, I heard a clinking noise coming from below. It sounded like two jangling keys or some light pocket change. I'm thinking I chipped a tooth on the transmission, probably 4th gear. But I took it on a test run today and she seems to shift and run fine on all 5 gears. Is that any indicator that it's not the transmission that made the noise?
