I had a frightening experience this morning. As I was getting ready to pull into my work parking lot this morning, I noticed my clutch pedal was softer than normal, and it was difficult getting it to go into 1st gear from a stop. When I went to back into my parking spot, the clutch pedal became very soft, and it would not go into reverse. Major grind, not good. Had to slam it into reverse to get the truck out of the middle of the lot, and back into my spot. (I know, not a good thing to do, but, had to move it quick.) Then, when stopped, with the now very soft clutch all the way to the floor, even after several seconds, it doesn't want to go into any gear, and will grind if you try. This is the 1st stick shift I've ever owned (should have bought another automatic). Any opinions or thoughts on what part or parts might be going bad, or already broke? If it's any help, it's a '79 with the SM465, and the clutch is all manual with linkages (no hydrulic assist). Thanks much.
