output speed sensor

  1. XD (2001-2006) Elantra
    My car when I pass more than 50 Mph, my transmission goes down to 3rd gear from 4th gear and I put my OBD scanner and I don't remember exactly the code I think it is P0721 but I'm not sure, but I remember that the scanner seems to me the output speed sensor OSS was damaged, this is the sensor...
