Where is the vehicle speed sensor located? on 2005 Pontiac Aztek

Speedometer is not working properly. Sometimes it stays on 0 mph. Other times it shows an incorrect speed. Other times it works correctly. I'm thinking it is the vehicle speed sensor. Even if it's not, it only cost $15. Can anyone tell me where it is located?

The vehicle speed sensor should be mounted on the transmission. Speedometer stepper motors are a common fault with GM products.
