Its more than likely the NSBU switch on the transmission. You can get them at NAPA and replace it. What year is your truck?

It is probably the NSBU switch. It is located on the driver's side of the trans. Common problem when they get water, snow inside of the switch.

It will usually say "Shift Range Inhibited". Do not buy from the dealer-- $$$! Allison or NAPA is OK.

PM sent!
