Well, from high, to low. Sounds like a failed throw out bearing. Just a casual drive into work this morning, all was well, just went to shift into 5th and it grinded, this tranny has never grinded before. When I got to the off ramp, pedal was hard and made a grinding noise when trying to push it. This happened about 2 km from work so I shut it off, put it in 1st and started it, yup rolled even with the pedal pushed in. So I finished the journey in 1st gear. Popped out the clutch fork boot at work, can't see anything abnormal, slave is working properly but the pedal still feels wrong. Looks like I know what I'm doing tonight.
