Hey Everyone. I got an used mustang a couple months back. I was driving up the road and went to shift to second. Halfway through shifting all my gears locked up and I got stuck into neutral. the clutch lost most got stiff and it wont let me go into any gear while started. When I turn her off the clutch moves fine and I can put her into gear. The clutch was supposedly replaced not too long ago and gave no indication of going out, it just popped and wont go into gear. Any tips? Im a new owner and Im not sure where to start.
