I haven't visited this thread in a while but I feel the pain you guys are going through. Consider this for a moment:

Whie it is possible that one or even two of you may have had a faulty throwout bushing/bearing installation, it is highly improbable that all of you or your installers can not master the installation of a throwout bearing.

The drag of an improperly installed or worse failed throwout bearing or an improperly adjusted clutch can overwhelm the synchronizers and produce the problem you are experiencing. The problem can also be produced by synchronizers that are barely up to the job of synchronizing the gear sets.

The problem is the latter not the former. The synchros in the TKOs are brass rings like we used to see on T-10s, Toploaders, and A-833 Chrysler 4 speeds. With the new lubricants, and metal finishing on the the synchronizer gear cones the plain old brass rings can't do the job anymore.

If you look at a T-56 they went from paper assisted dual friction surfaces to triple cone versions of the synchro to get improved shift quality. Tremec knows the problem there just hasn't been any fix available or desire to provide a fix - until now.

If you go to Liberty Gears they have an improved synchronizer available with a carbon fiber friction surface. They also have a retrofit to correct the 2-3 shifting problem. The synchros were about $50 each when I last checked and the shift fix was comparably cheap. Give it a try you'll like it.
