P0720 Output Speed Sensor Help

Just wondering if anyone had a part number for the sensor and any idea what it costs. Would my local dealer know what I was talking about if I asked for an output speed sensor? Also, any recommendations on MOPAR vs Autzone part for this ie better quality ect..

Thanks for any and all help with this

Part # 4800879 should run you about 20$ at dealer. At that price why even deal with auto zone.
