trying to get car inspected

"where do I take it to get fixed"

Take it to a repair shop.

Why do you come here to ask the obvious??????????????????????????????

I know a shop just down the street from me.

If you're a do-it-youselfer, you'll need to remove the air box and unbolt the bracket holding the transmission cable to the top of the transmission. The sensor is partially under that bracket. Simply unbolt it, take it out, and install the new one. Be sure to clean the area first so debris doesn't drop into the transmission.

You are not the first Santa Fe owner with this problem. see the following thread.
