This is about my friend's integra. He called me last night about how is car is shaking and just feeling really bad so I took a look at it earlier today. I can feel the clutch pedal shaking quite bad and when I put the car in 1st gear to drive, the car shacks really bad, feels like the clutch is not hold.

So, what's the problem? The clutch? Or just the fluid?

Thanks in advance.
