I have had this issue for weeks (not shifting), and I have inspected the clutch holder closely. Everything was in place on the clutch holder before I ran it recently (the day I posted this question) but I knew that the clutch holder might be the issue. After reading the responses, I am certain. However, I received the new clutch holder in the mail today and opened the transmission case to install it... Wow!
The adjustment screw was missing as was the spring and the ball. It was completely assembled before because I inspected it, but obviously the nut backed out and everything behind it followed. Luckily nothing was thrown into the gears and caused a bigger problem. Each part was laying in the case on a layer of grease.
I installed the new clutch holder and placed a conservative amount of thread lock on the adjustment screw. Hopefully this will prevent the issue from happening again. I also reassembled the stock clutch holder and when I tightened the adjustment screw it seemed to function correctly.
What does this mean? I don't know. I would assume that the spring, after a couple gallons of fuel, needed to be adjusted and compressed dramatically to function properly as it had before. That made the truck start in second gear and left a gap between the spring and screw that was wider than I expected so when I adjusted three turns in, it probably had JUST started to touch the spring and still didn't correct the problem. The gap also might have caused grease to find its way between the spring and screw. Then when the engine ran vibration and adjustments I made only lubricated the path and allowed the screw to back out completely.
No matter- It seems this must be the problem. Weather was too sketchy for a run today to test it, but when I do I will return with my final conclusions.
