The Ford Barn - View Single Post - New transmission locks up. Only spins free in neutral. Thoughts?

Now I'm completely stumped. I swapped the 28 tooth cluster out for another 28 tooth cluster that came from a 40's car.

Still locked up in all gears, but neutral and the the input and main shafts will not spin independently when in neutral. It is either the synchro hub or the synchros themselves.

When the input shaft synchro is pulled away from the synchro hub, it works as it should. When mated in the hub like it should, locks up.
