I have a spec stage 3 that I have had for 1 year. It has worked fine so far except that now I have a bad vibration in my trans. I am not sure if it is the clutch or the trans. You can fill it with the clutch in or the out and mostly at high rpms. I have heard of problems with spec clutches and I am wondering if it might be the problem and if it is so I can talk to spec and see if they will take care it since it is not a cheap setup. Any advice would be appreciated.

 

May want to check the tranny mount. Could be as simple as that. Then work your way towards deeper issues.
