Not sure what trans you're running, may be similar to the one I have (though mine is out of an '86). I have the D/R, and it is a 4 position lever. Bottomed out (no downward play in handle) is FWD only. Up once is 4Hi. Up again is True Neutral/Towing. Up one last time (3rd time for those not counting) is 4Lo. From time to time she gets twitchy, whether out on one of the "Primitive Roads" we have out here, or my 1/4 mile long curvy, hilly driveway she decides she doesn't want to come out of 4WD, no matter which range. When that happens, I put in the clutch, put her in reverse, let out the clutch until she's just starting to move, then back to Neutral. She'll let herself be put back in FWD then.
