I believe your car has a t56 transmission, correct? If so, there is a bushing in the extension housing that keeps the clearance between the yoke and the extension housing tight to keep the yoke straight and concentric around the tranny output shaft. Now excess clearance between the yoke and bushing will allow vibration to occur. If you have a problem with the clearance that is causing the vibration, it can be due to either a worn bushing, a worn yoke, or both. So there are a few possibilities that would cause you to have the vibration after switching the transmission and/or drivershaft. Most likely, both the yoke and the bushing on your original equipment are worn. If so, then you would still experience a vibration by swapping the tranny and using your original driveshaft due to the worn yoke. If the ebay tranny didn't have the bushing replaced (which I wouldn't know), then the worn yoke would be compounded by a potentially worn bushing. Now to the swapping of the 01 aluminum driveshaft...If you swapped the 01 driveshaft into your original tranny, then you would likely still experience a vibration due to the worn bushing in your tranny, but it would likely be decreased because though the bushing is worn, the clearance between the "newer" yoke and the bushing would be tighter than that of your steel driveshaft's worn yoke. This is consistent with your post above indicating the vibration decreased when you swapped the driveshaft. Have you tried the 01 driveshaft with the ebay tranny? In theory, this would be the best combination to determine if this is your issue. I hope this helps.

Yes I did. I had the ebay trans in with 2 diff driveshaft... the last thing I did was swap back to the OE trans.
does anyone have a write up on doing the tailshaft bushing in the transmission in the car?

do you have a poly trans mount and rubber engine mounts? If so, change the poly mount to a rubber one.
t56 trans' are very sensitive to output shaft harmonics, and in some cases have problems with looseness in the 5-6 cluster extension(should be pressed on and off, sometimes they are not that tight and cause weird vibrations)
my brother had a weird resonance/vibration occurring in his car due to the mismatched engine mounts. once we put the rubber mount in the car, the vibrations went away.

No sir. Apparently it has to be done with the transmission out of the car... Im going to throw in a rubber trans mount for kicks and giggles... if that doesnt do it then im just going to send the transmission to tick. IDK what I will do with the ebay transmisison, maybe try to fix it myself.

I was told it has to be done out of the car... I just think its odd how 2 transmissions could have the same issue. I guess ill just drop the trans lol

Is the tail of the T-56 removable like a 4L60e is? If so, just pull that off and leave the trans in place. Should be able to get it done that way.

The tailshaft has to be removed outside of the car. you can take it off in the car but cannot put it back in. I am tempted to bring my ebay trans to hanlon and have them look at it. see if anything is bad... and if nothing is bad...... then.... i guess i need a rear lol

Update. Swapped the rear. issue still there. I am going to look into the complete driveline angle (including trans, not just the rear). I set the rear pinion angle to -1 but didnt account for the trans...
Great info on LS1tech

NOPE. still there! swapped rears, transmissions, driveshafts, everything...
surprised you remembered  I am thinking its the whole angle of my transmission and rear. I never measured my transmission angle.
Lots of great reads on my recent LS1 tech thread

Very few from the Flemington area here, so yeah, I remember you!
Def. check the pinion angle w/ that adjustable TA.
