Suddenly my chatter has got louder and even hear a chatter/whirling sound at idle and when not accelerating. With the clutch pedal pressed in the chatter/whirling sound goes away but I hear a grinding sound.

changed transmission fluids and it was black and greyish. I had some metal shavings.

 

The chattering sound you're hearing at idle and probably under deceleration is your throw out bearing. Have you changed your clutch recently? Mine got noticeably louder when I changed to a 6 puck.

 

Mine does this as well. Almost sounds like a rod knocking around in the block and people riding always ask if its knocking and when I push the clutch in it stops and I gotta show em its not a rod knocking.

 

It's a exedy twin and I know it's not normal clutch chatter you get from twin disc's. It has about 20k miles on it. Chatter is really loud it drones out the motor.

 

bump anyone?
