Violent shakes on 1st gear take off Options

Havn't been able to find a answer to this one. When i take off in 1st at about 2000RPM the vehicle shakes violently, but continues to move forward, stops after about 3 seconds. When i say shake, its more like the car is jumping off the ground and slamming back down within seconds of it self. I assumed it was the clutch slipping. Clutch is brand new though =(

What i have been doing to make it not do so, is get her going slowly let the clutch fully engage drop down to about 1000rpm, and its fine if i do it that way, no shakes at all. Doesn't do it either if pop the clutch and take off, only on progressive take off. Sounds more to be vehicle error then driver error, but ya never know. Any idea guys?

hmm, one thing I did forget to mention. When I purchased my celi the fools that did the clutch did not put fluid back in. I drove around for about a week without it, before the local shop told me and filled'er up. With the fluid inserted it was quite a bit less often, but every now and then it will do it. Another thing I've been noticing is the clutch is alot higher in the pedal nowadays....think its time for a "new" new clutch...possibly performance depending on the bank statements.
