If that was true, why would it be OK if he shifts gear to gear relatively quickly, but not if he waits in neutral?
According to your theory, both shafts would continue spinning more or less as they were, since the clutch would not disengage (slave cyl theory).

I still want more facts - every gear ha this problem?
