Speed sensor replacement

I have 2001 Rodeo V-6 3.2L with 165,000 miles. My speedometer and odometer stopped working yesterday and the check engine light came on. I got the code checked at Autozone and it is P0502 (speed sensor). Is this something I could fix myself and where do I get the part?

Not even sure where this sensor is at. Also, I'm not real skilled with electrical stuff.

Thanks
