My 2000 mustang gt with 120K miles completely blew out the clutch without any warning. My 5-speed shifted perfectly, no slip, it was very firm. I was doing about sixty five and went to downshift from fifth and it simply didn't go back into gear. It was in neutral and would go back into gear when engine was turned off. I got it to go back into gear and take off with a lot of grinding sounds - and i could smell the clutch burning. It takes off really slowly with very high rpm's - and I know its slipping like crazy. My question : is it the clutch or the clutch cable?
