I had all 4 tires off the ground and the transmission in neutral. And while manually shifting I could only get 4-Hi, Neutral and 4-Lo. It definitely felt like there was one more position from 4-Hi going the opposite direction of the Neutral position, but i couldn't get it to click in to place, even with a cheater bar on a stubby wrench. I read another post, where people have been able to get a troublesome transfer case to shift to 2-Hi by driving in reverse and then selecting 2-Hi, I'm thinking if I put the encoder motor back on and try shifting while driving in reverse, that will be my last possibility before declaring the transfer case shot (even though the encoder motor was diagnosed as the bad part by a transmission shop). Thoughts? Thanks, Joe the history for this issue is: I am doing the transfer case encoder motor fix on my 2002 chevy silverado. The obstacle I've ran into is, after I got the encoder motor off I decided to cycle through the 4 different transfer case positions, I can get 4-Low, Neutral, and 4-Hi but I can't get it into 2-Hi manually with a crescent wrench. Is it possible the transfer case has seized up? I did a transfer case fluid change and it improved the manual shifting between the 3 available positions but I still can't get the 4th position. Has anyone else had this problem? Any suggestion?

I haven't had the tires off the ground when manually cycling through the positions. I've been able to shift to the other 3 positions with the tires on the ground, the transmission in neutral and the parking brake on. Next time I'm working on it I'll jack it up and see if that solves the problem. Ouch.....I can't imagine how the shaft could fall inside, but I'll keep that in mind when manually cycling.
