806 diesel shifting problem

I've got an 806 that is made into a high-clearance sprayer with an 80 foot boom. It is made to spray tall corn or short crops. I've used this tractor for 15 years and never have had any problems. It has about 6-7,000 hours on it and was ordered new from the factory without a TA. A problem developed this summer when I was spraying beans. I would like some ideas on what it could be. I spray in 2nd High about 1800 rpms. It started kind of making a catching or clunking sound and it felt like it was popping out of gear.
I drove it to the shop and had an IH mechanic come out to look at it. It works fine in the low range and reverse. High is the problem. He took up the plate under the floor and thought things looked pretty good but the shift fork was worn bad and the bushing that the fork goes over and moves the gear was wore pretty bad on one side. He thought by fixing the fork I would get by OK.
But, that didn't fix it. Now when I put it in any of the high gears and let the clutch out, it just makes a high-speed grinding noise and it won't even go into gear very often. Just wondered of you think it could be something like the eye bolts in the linkage that could be bad or maybe the nut with the keeper on it that holds the main shaft with gears on it in place has come loose, and will require a split.
