I've got my tranfer case stuck in 4WD low. No matter what I've tried, I can't get it out of low. Is my transfer case shot? I have a full size 85 Chevy Blazer, 350 with 700R4 transmission. The transfer case was supposedly rebuilt when the transmission went out last year. I've adjusted on the linkage. The transmission will shift gears, but no matter what position the shift lever is in, it is always in low gear.
