Clutch engaging before normal point
I've got a Centerforce Dual Friction clutch in my 01 SS. It's got a pretty high engagement point, almost right at the end of the pedal swing. My problem is that lately when the clutch is coming right off the floor it acts like it's going to engage (the car creeps a little and the RPMS slightly drop) then it "releases" - it goes back into neutral and the RPMS go back to normal. Then I have to let the clutch out to the normal point and everything works fine. Could it need to be bled?
Also, there is a chattering coming from under the car when it sits in neutral and sometimes if I shift a little too soon. I searched and found this could be due to the performance clutch, but could it be the throwout bearing? Thanks for the help
