Clutch Problem

I have a 98 Sahara with about 68K miles. Last night, the clutch worked fine. As I was leaving this morning, I heard a grinding noise when I push the clutch in. I cannot go into any gear at all. The engine turns over fine. There are no apparent leaks. A co-worker checked the reservoir, and he said the fluid level looks fine. My boyfriend is away. I hesitate to take it to a mechanic without first having an idea of what is going on. Does anyone have any insight on my problem? Help!!! Any feedback will be greatly appreciated!!! Thanks!

I'd go to the dealer right away; you're probably still good under the 7/70 powertrain warranty. If so, they will fix it for free. From your description it sounds like some work needs to be done.
