I still think it is related to the torque converter. It's like whatever is supposed to tell the torque converter to lock up is not sending a constant signal making it shutter. The new torque converter is doing the exact same thing that the old one did. I guess it could be a sensor. The entire drive shaft was balanced and all joints replaced. The pinion angle was checked at re-installation.
I had a similar issue with a 1984 S10 Blazer, we unplugged the converter lock and the problem went away. Back then there was only 12 month, 12000 miles of warranty and GM would not make it good. We drove it like that for about a year and traded it in on a new car, this was the first year of the S10 Blazer, it appeared to be built well with good fit and finish, but between the vibration issue and the multitude of rattles around the tailgate and rear window that also could not be corrected we elected to get rid of it.
I would try to disconnect the lock circuit for the converter and see if that is the issue.
