Won't Shift into 4WD unless <15mph
Until this year, I've been able to shift into 4wd high on my rig (2007 5.9, electronic tc, 273 I believe) at pretty much any speed needed. This winter I couldn't get into 4wd (blinking light) until I slowed way down, to 10-15mph, then it would engage. It wouldn't unload/get out of 4wd and back into 2wd until slowing back down again either to the 10-15mph range. I just replaced the shift motor on the transfer case thinking perhaps it was weak, but still no go. No codes show up either. When it shifts, it's nice and smooth, no noise during or while driving. New tires, balanced and worn fine with less than 10K miles on them. Any thoughts?
