Allow the engine to cool completely. Disconnect the negative battery cable using a 13 mm wrench and lay it beside the battery so it cannot accidentally touch the battery terminal and cause sparks.
Disconnect the electrical connector from the sensor located on top of the transmission bell housing angled slightly to the driver side of the truck. This connector is equipped with a red locking tab that must be pried out of the connector with a small screwdriver before the release can be pressed to remove the connector from the sensor.
Remove the two 13 mm bolts that attach the sensor to the bell housing. Pull and twist to slide the sensor out of the bell housing and lay it aside. Insert the new sensor into the bell housing. Reinstall the bolts and tighten them securely.
Plug the electrical connector into the sensor and slide the red locking tab into place.
Reconnect the negative battery cable and tighten it securely. Start the engine and test-drive the truck to verify it runs properly.
