I broke mt T56 today it grinds realy bad when you let the clutch out in neutral or any gear. I pulled the tranny hoping the clutch was spent but it is fine so I sit the tranny on the floor and put in neutral and I can't turn the main shaft by hand so I assume something came apart inside? That shaft should spin easily when in neutral if I remember correct. My brother will be rebuilding it with some D&D parts
