Default Vibrations

Why does my shifter vibrate and the car shakes very bad when I rev it up in Neutral? Also whenever I somewhat lay into it, around 2.5k rpms, the shifter started shaking and vibrating violently. The only thing I can think of it being is a warped clutch. Any other opinions?

Also the car shifts normal, there are no weird noises coming from the shifter area when idling or driving, and there are no weird noises coming from the shifter area when the clutch pedal is pressed in or depressed.

Has anything been done lately to the car ? If so thats where I would start . It could be a balance issue or even the exhaust hitting on the body somewhere .

Maybe a bad tranny mount?

With the clutch press in, it revs up fine. when the clutch is depressed (my foot off the clutch) and i rev it, it vibrates and shakes.

Sounds like a transmission problem…I would call Amber. When your foot is depressing the clutch pedal the main shaft in the transmission is not spinning at the same RPM as the engine. When you release the clutch even in neutral the main shaft is spinning at the same speed as the engine, this is when I believe you said you have the vibration? The other things that can cause a vibration are a bad disc or worn pilot bearing but you didn’t mention any clutch problems?

Hope this helps?

This is on my C5. I've been told it could be anything from the slave cylinder to the torque tube busings. The tranny is in the rear of the car, there aren't any weird sounds coming from it.
