Is it my rear end? I have this vibe in my car above 80mph. I also have what seems to be the same vibe at low speeds but only when turning. Could this be my diff. It al started when I put in my 4L70 and TP4000. But I actually think I just feel it more because of the way the 4L70 crossmember and TQ arm mount are. I would like to get this fixed before it goes south. Is it my A$$?
Thanks

There are doctors for this type of thing. They are called proctologists. <img src="gr_images/icons/wink.gif" border="0">
Could be that the driveshaft needs to be balanced, or maybe the flexplate got damaged during the 'verter install?

Yes that's absolutely true.
Vibration is from the torque arm bolting to the crossmember transmitting to the body, instead of the trans which absorbs the vibe. Also you are using a poly bushing with the 4l70E instead of the rubber one. It is a stronger trans, but you have to live with the noise. You could add more insulation.
