Ok i'm getting buzzing from the engine when decelerating in second and third gear, i understand that it maybe fixed by replacing the clutch from the service bullentin but i also get violent shaking also, any input is welcomed.

 

Just what do you mean by "violent" shaking? Do you mean vibration? Violent shaking sound like a major problem. Take it in.

 

Well by violent shaking I mean the whole car jerks back and forth. When i down shift from 4-3 or 3-2 and release the gas, the buzzing comes from the engine and the car shakes violently now i'm not at very high rpms either say about 3-4

 

That doesn't sound good at all. Like cthree says, just take it in to get looked at.
