I am going to assume when you say it “shifts” you mean the shifter lever will move.
I would first check your Park Brake. Then Check Your Fuses. If that is OK. you will need to check your gear selector switch. Then the Vehicle speed sensor and then the Transmission control module along with all wiring in between.
If this is 4WD the transfer case may be stuck in neutral.
