About halfway back from lunch today, I found that I had to force the lever to get into ANY gear. Only by perfect rev-matching could I easily get it into fourth (the needles usually line up in that gear, making it easy).

The car was fine this morning, no problem shifting at all. A friend of mine suggested I have a clutch problem, either with the master or slave cylinder. Any suggestions?

 

check your clutch fluid

 

First thing I checked. The resivoir still has fluid - it looks like I wouldn't be able to get any more in there if I wanted to.

I'm pretty sure it is the clutch, now. I've had trouble getting it to take first without lurching.
