HELP!!!

If you feel a vibration when releasing the clutch, usually you have some hot-spots on the flywheel and you will need it resurfaced. If you feel the clutch slipping, like you said it doesn't hook right away when you lay in the throttle, you will need to replace the clutch. Re-surface the flywheel whenever you put the new clutch in. The tranny shouldn't be low on fluid unless it is leaking. You can check the level by taking the fill plug out of the passenger side of the tranny and stick a finger in the hole and feel for the level. There is also a drain plug on the same side if you decide to change the fluid, and can refill through the top fill hole (squeeze bottle or pump) or you can pull the shifter off the tranny and refill there. I bet you can change your clutch yourself, you can get alot of help on this site to help you along the way.
