I have a B16A(hydro) in a 93 hatch and a week ago it became very hard to shift. I push the clutch in and if feels like its not. I had someone else push the clutch so could see if the fork moved and seems to go all the way. I took the clutch out and looked at it and it was fine but still does the same thing. Could something broke in the tranny would cause it to do this or could it be the clutch master cylinder? Thanks
