Output Speed Sensor

2001 Elantra and she suddenly shifted into 3rd, got her coded and it came up Output Speed Sensor Circuit. Easy to replace and must I drop the pan (need to get the Haynes out I guess).

Output speed sensor is on top of the transmission. There is an output and an input right next to each other.

Thanks again for the quick response.

John, do you have a part number for that item, I cannot find it online at any Hyundai suppliers.
