Default Random Shifting

I got a used Twin Hammers here recently and I’m having a problem where it is running along and it will suddenly clunk, grind, and then shift gears on its own. Any idea of what could be causing it or how to fix it?

Thanks!

It sounds like the shift servo might be on the fritz. A bad servo can move on its own without any input.
