when you go to shift with the chicken stick (the transfercase stick) you'll have to put the truck into neutral to get it to go into 4low. that's pretty much the only other trick i know. Other than that, the button for the shif lever has been known to stick, so make sure you press that good. If that doesn't wirk check to see if something is in the way. but the neutral trick should work.
