Absolutely. You do not have a speedometer cable. The vehicle speed sensor, at the transmission, sends a signal to the computer. The computer then positions the speedometer needle based on the signal from the vehicle speed sensor. HTH. -Jim

It's very likely that the sensor has lost it's calibration. HTH. - Jim

Changed the speed sensor located on the transmission, still have the problem. Speedo is pointed almost straight down not at zero. Anymore suggestions?

I'm sorry to hear that! The only other 2 things it can be is the instrument cluster or the BCM (Body Control Module). Unfortunately the speedo isn't serviceable by itself. HTH. -Jim

It is the Stepper Motor. Your best bet is to send it out for repair. someone like this http://drspeedometer.com or this http://www.speedometerrepairguy.com/pricing.htm or many others that you can find on the internet.
