Most sensors are inside the pan and in the valve body. This is best left to the guys that do it all the time. Get a bid from a trans shop. It may not even need the sensor. The indicates a circuit issue.

I have replaced dozens of these sensors for this code. Without proper testing, it is only a guess if the sensor is the culprit. It is located under the battery tray secured by one bolt.
