Correct. That hard gritty stuff is burned clutch disc friction material.They're shouldn't really be none unless one of the clutches is starting to go right?
I think you're probably on the right track.Machine has still been working. 1st gear seems as if it's getting worse with the sporadic stops. Been using it in 2nd gear and working fine just pushing garbage off a slope with no real hard pushing. I think I might have to pull the transmission.
