No, you should be able to get into 2-hi fairly easily. Sometimes, as I mentioned before, there is some bind in the TC, which makes it difficult to shift back into 2-hi. If you roll it backwards a little, then go into neutral (on tranny) it tends to free up the TC and you can shift it into 2-hi. If not try doing like I said roll it forward a bit, then try shifting, if not then back up again. This usually works for me and I have seen others give the same advice. Also, everytime you unlock the hubs (coming out of 4wd) it is a good idea to back up the truck 20-30 ft to allow the hubs to completely unlock. I hope that you get this straightened out. Let us know what finally works for you. I typically always switch gears in my TC while I am in neutral, if I get any bind, I put it in gear, nudge it, then it tends to shift nicely. They are a bit tempermental....and at 30+ yrs old, they have a bit of a right to be. I know its getting close to rebuild time for mine. Good luck.
