When you disengage the clutch, two bearings begin turning that don't turn
the rest of the time: the Pilot bearing and the throwout bearing. If you
push the clutch in when sitting stopped with the transmission in
neutral, the transmission should stop. You can test whether it's stopped
by attempting to put it in reverse because reverse has no synchronizer. If
it grinds, ether the clutch is dragging due to maladjustment or the pilot
bearing is seized or about to seize. IF the noise stops when the
transmission stops there's a problem in the transmission. If the
transmission stops when you depress the clutch, and the noise gets worse,
then it's not in the transmission. This could also be the thrust bearing in
the engine. That takes more stress when the clutch is disengaged.
