vibration problem! I just installed a new tranny, and vig. converter in my 00c5. drove for a week, then went to the track a week ago. made 3 passes total. second pass when I was slowing for the return lane, I heard a noise like a swishing noise from under the car by the shifter I think? Now when I drive normal there is a slight vibration above 55 to about 75. but when accelerating 2/3 throttle, It vibrates the seat,floor pretty good. If I hit it full throttle, is goes away?
I checked the converter bolts again, balancer bolt, changed d.r. to street tires. So far, 3 poeple have told me to take torque tube apart and check the couplers and center support. any other input the same, or other things to check.
thanks Nuzz

I have almost the same problem. I have a 00 SS Camaro, I have had rear vibration 55 to 80 mph. Have done alot of research and nobody seems to know what the problem is.The tranny has been checked and the drive shaft, rear tires and rims which leaves axles or rear seals or the the whole rearend it self. Also vibration gets worse in 3rd gear. Has anbody ever had this problem?

No i don't have an aftermarket torque arm, everything is factory as far as that goes. What is the work going to cost you if you don't mind me asking? Let me know if that fixed your problem. My car has been like this for quite sometime now, just got tired of going to different shops, surprisingly nobody never knew what was causing it.

I had this problem a few years ago with a GM car. I was convinced it was the tires, but it turned out to be the U-joints. They were also set in plastic. I pressed out the old U-joints, put brand new ones in from NAPA and the vibration disappeared. Good luck.
