I am replacing my factory Hu-555 radio in my 2004 Volvo S40 with an indash naviagation system. Does anyone know where the VSS (Vehicle Speed sensor ) wire is located. I know that one runs to my factory radio bc it has the function to adjust the volume based on the speed of the vehicle. I just need to figure out the actual color of the wire so i know which one to tap into so the navigation can know how fast my car is moving so it can give me a more acurate reading...

 

That's the strange thing,there is no odd noises coming from the transmission at all. And when you pull the sensor an look down into the transmission,you can actually see the gear that is hitting the sensor.The gear it's self has very little play and and is preventing a new sensor from even going into the transmission.So it looks like something has shifted in the trans and moved this gear into the path of the sensor. The only physical symptoms I'm having is first gear is holding a little longer and the shift into second is rougher then usual and any down shifts are pretty rough. The up shift light is flashing,Econ/Sport switch indicator light is flashing, check engine light is solid.
