I don't think they are related. Do you have a scanner? If so, scan the computer to identify where the problem is coming from. If you don't have one, most nationally recognized parts stores will do it for free. Chances are you have a bad vehicle speed sensor (VSS) at either the front or rear of the transfrer case.
Let me know what you find or if you have other questions.
