So I was driving from the hardware store yesterday with parts for my other car, suddenly I was trying to shift into second gear when it made a grinding noise. Then I made another attempt and nothing, so I tried getting it into any other gears, but still nothing.. The car idles fine, just can't get into any gears. When I press the clutch pedal it feels really loose for the first quarter of the push, then it feels kind of spongy/stiff for the rest of the push. I looked under the dash and under the clutch pedal and noticed moisture on clutch Master cylinder, so I wiped my finger on it, and sure enough it was oil. Could the master cylinder be the cause of my problem? Sorry for posting in wrong section, but this is the only place this site will let me post

 

Sounds like that could very well be the problem. If you have a helper, you can have them look at the slave cylinder while you press the clutch to see how much travel there is.
