ok so here is the story. About to months ago I went to the track and did a hard launch and I heard this horrible sound coming from the transmission, and I could feel the vibration of this noise in the clutch pedal and the shifter. The noise increases with rpm. I figured there was something wrong in the transmission, so i went ahead and ordered another transmission, and after I put that transmission in the car is still making the same noise. I know it is not the rear diff or the axles cause i checked both of those and the noise is definitely coming from the between the bell housing and the motor. So I think it is something to do with the clutch. I got the flywheel resurfaced and a new clutch disc when i put the new tranny in. The throwout bearing was also checked and there was nothing wrong with that.

I know it is not a dropped valve or anything from the engine cause i was able to drive it 80 miles home from the track when the incident occurred and there was no problem.

Wut do you guys think the problem is? any help would be much appreciated. Thanks.

 

So, you bought a tranny just like that without having a diagnosis? That's gangster!

 

yes I did and now i am regretting it. Does anyoen have any idea what the problem could be?

 

Ouch, did you change the pressure plate? Good luck man!

 

no i am using the same pressure plate that i was using before. It seemed fine. All the splines were in order and it was holding the clutch disc quite well.

 

anyone else have a similar problem. I starting to think of the worst case scenario of the crank rattling or something. I'm really worried.

 

does it happen in every gear?

 

mine does the same exact thing, but only when i let off the gas, the vibration is huge especially in the clutch pedal, i think its normal, at least thats what they told me when i posted up a simliar thread.

if i let go of the gas at about 3k rpm then it makes an extremely loud buzzing/vibration.

 

yes it happens in every gear

 

in gear and off the gas pedal i get the same sound...
