Well, after many moons trying to figure out this damn vibration in the Stang, I finally narrowed it down to the driveshaft!! Lots of thanks to everyone who helped troubleshoot it! It turns out that the people I had put the 3rd T-5 in didn't feel it necessary to tighten the bolts on the driveshaft. I could loosen them by hand and it was so loose you could wiggle it. Even though that was probably why it vibrated, I put in the Aluminum one anyways!(of course!) But I can bring it to redline once again without it feeling like it's going to vibrate apart on me!

Just thought I'd share a good thing!
