I did the t3650 swap into my 97 cobra and I love the trans and the new clutch. But there one problem. I noticed today that at around 2,000rpm it has a vibration to it. I think it may be the the clutch/flywheel but I am not sure. I used a flywheel that looked good and had about 19000 miles on it. I didnt get it resurface, I just used sand paper and got the glaze off of it. Also I put the driveshaft back in the holes where it had been the last 9 years. The vibration is bad because it right about 65-70mph in 5th. And it is enough to numb your legs. Also it is not constant. It is like a humming that comes and goes consistantly about every 5 seconds when I am cruising at around 70. Any ideas??? THANKS

what happens when you're going 65-70 and you push the clutch in?

still vibrates...but I get a similar vibration when the car is not rolling and I rev it to 2 grand. So it may be a bit of both. But i am not sure. I was going to index the d/s today I can clearly see where it was from the factory.

Did you tighten driveshaft right? Our driveshaft is bit of pain to torque down evenly.

its just hard, because you have to lock tires to tighten 1 bolts, unlock your tire, spin the shaft, and lock it then tigten. its bit time consuming. So sometimes people don't do it right

We did that. It's probably the flywheel not being resurfaced I'm guessing. I'll go for a ride and see if I can feel where its coming from... btw did you ever re-torque that right front wheel???

the vibration feels like iti scoming from the rear but could it be that the flywheel bolts are coming loose, or that the flywheel needs resurfaced???
