Most new GMC vehicles use an electronic speed sensor. Check underneath the vehicle for rubbing wire harness against the drive shaft, or possibly a loose / disconnected electrical cable to the transmission.

You might need a new speedo cable but if its a sensor you could need a new sensor and that might not be cheap.
