The car has 112k miles on it. I installed UMI's 3 point SFC and then took her out and beat on her a bit. The following day I started it up and had a very strange noise under acceleration. It sounds like a bicycle chain rubbing on a piece of sheet metal. The noise occurs under WOT, it begins at around 3k rpms and continues until I let out of it.

The noise sounds like its coming from the dash when you sit in the drivers seat. I had a friend ride with me and he said it sounded like it was coming from the shifter. You can feel a slight vibration in the pedals and shifter when the noise happens. This makes me think it is the transmission.

With my car in neutral with the clutch engaged the T56 is silent. After the noise started I changed the transmission fluid and did not notice anything in the fluid, nor did the noise go away. I have climbed under the car and tapped on the exhaust, trans, crossmember, re-checked my SFC bolts and cannot duplicate the noise. Does anyone have any idea???
