Thanks ChargerST - you confirmed what I basically came up with last night. It also correlates with the behavior I noticed when driving. I didn't drive far, but when I did try to accelerate in 3rd, it didn't want to speed up! I believe I was fighting this cone/synchro interference.
I will pull the transmission and then I'll need to figure out what's causing the sticking. I wanted to be driving this thing by now! Ah well - that is the way of life.
