we need to hook up our RV to the truck and take it north with us tonight for my grandpa's 105th birthday, and i ran into a problem. the transfer case wouldn't engage neutral. the neutral light would flash a few times and then "Service 4 Wheel Drive" would come on. i need to get this thing hooked up and tow, or else i won't get to see my grandpa turn 105. than that would be the icing on the cake. the crap would hit the fan.......etcetera. what can i do to get this thing into neutral?
