My daughter's 04 Neon SXT threw a P0720 trouble code today. I want to replace the output transmission speed sensor. Can someone tell me where it's located, and some quick info on how to replace? I'm not too familiar with this car. Thanks!
Sorry I just now came across your post. It's on the top of the tranny. Just be sure once you remove the screw you carefully remove it STRAIGHT up. The gear can come off the sensor and fall down into the trans.
If changing the sensor does not fix it~ the prob is either the wires to it or the plastic gear that rides on the diff has come loose. Hope it's just the sensor.
