My car was shifting hard yesterday, I thought nothing of it. Today I get in and try to start it up, no problem. It won't go in gear, I tried kind of hard, no deal. Damn..so I shut the car off, put it in gear, start it up, I move. Is it possible for this to be anything but my clutch? The clutch might be 18 months old, but I've been hard on it. If this is my clutch, what upgraded clutchs are recommended. Thanks for any help.
