I just bought (another) 65 bus. One of the reasons it was going cheap was that it has a strange trans problem that I can't figure out. It starts just fine and runs in neutral with no strange noises or anything. When i shift it in to gear and start releasing the clutch it makes a terrible grinding noise, like a gear not fully engaged or something. I tried it in 1st, 2nd, and 3rd gears with the same result, except that the higher the gear, the faster the grinding noise, so I'm thinking it has to be on the output end of things. Broken spider gears maybe??!! Ideas? Thanks.
