OK, so I was late for work and brought my car up to like 135. since then it vibrates like CRAZY if above 5,500 rpm. feels like a warped driveshaft but does not vibrate from speed, just rpm. does not matter if clutch is in or out. still drives perfectly fine up to 5,500. shifts easy, stops vibrating at 7,200 rpm.
I have solid engine and tranny mounts so i can realy realy feel it. any guesses?

 

Hmm, check out those mounts first...

 

the engine mounts are still in one piece but Im waiting for the rain to stop to check the tranny mounts. just feels like its too much vibration for it to just be a mount, maybe if both broke. if its doing it when I am stopped and have the clutch dissengaged doesnt that mean its before the transmission?
