    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?

    Yes!



    The T-dub tranny is very strong and will take a LOT of abuse, including no clutch shifting, so it's very unlikely. Could have been something caught in the chain that got thrown off shortly after. Check chain tension, a loose chain will rattle and clink on a shift. Check all bolts, the muffler, etc. Lot's of possible sources for that kind of noise, the least likely is your transmission.

    Probably fuel too low in the octane department.

    Wopachop was the one who broke a tranny tooth while in the sand dunes. He also admitted to doing no clutch wheelies or some such kind of hooligan stuff I agree with the posters above that it is probably something else. I had a good bit of piston, wrist pin cirlips, and timing chain remnants in my bottom end and the gears looked perfect (see my thread). A loose drive chain or worn sprockets can cause a skip going uphill or under acceleration that feels like tranny related problems. If you are worried about it, you can do an oil change and check your screen and filter for steel fragments or shavings. Dollar to donuts it is something other than the tranny.
