Is a clutch supposed to vibrate?
Warped Clutch Disc It’s made of a material similar to that of brake pads, and operates on the same principle of friction. In order to operate properly, all the contact surfaces of the clutch assembly must be smooth and flat, including the clutch disc. This results in chattering, vibration and clutch pedal pulsation.
Can a bad oil pressure switch cause the transmission to not shift?
Just like the above situation where the transmission has difficulty shifting due to a faulty oil pressure switch, this same problem can cause the transmission to not shift when it should. In this situation the engine RPM will be much higher than it should when it triggers the transmission to shift into a higher gear.
When does oil whirl become a significant vibration?
As a rough guide, oil whirl can become significant when the vibration amplitudes reach 40–50% of the nominal bearing clearance. Various corrective measures can be sought to guard against whirl conditions.
What is the ratio of rpm to whirl?
It has been shown that the shafting must rotate at approximately twice the critical speed for whirl motion to occur. Thus, the ratio of frequency to rpm is close to 0.5 for oil whirl. This phenomenon is not restricted to the bearing, but it also can occur in the seals.
What are the symptoms of a bad oil pressure switch?
One of the most common symptoms of a damaged oil pressure switch is a loose fitting wire that is attached to the switch and relays the information to the ECM.
Why does the clutch vibrate at 1500 rpm?
I have tested by going to 1500 rpms and slowly releasing the clutch pedal. It vibrates until the clutch is fully engaged (which is almost an inch off the floor.) Did the mechanic do a poor job or am I simply not used to the new clutch? Edit: I just realized that the car always vibrated in reverse.

What makes the torsion springs on a clutch vibrate?
As the torsion springs do their duty to absorb vibrations through gear shifts, there are several cone springs, friction washers and a friction plate to keep the torsion springs from vibrating themselves.
What happens when you put the clutch in gear?
With the clutch pedal pressed in and the car in gear on a flat surface, the car may creep forward. On the other end of the spectrum, the car won’t go into gear at all. With the transmission in gear and the clutch pedal depressed, the engine will stall. First make sure the car isn’t creeping because of spindown which is totally normal.
