I noticed this today on my way home from work. Pretty much does not matter what speed, the speedo needle will jump around while going down the road. Very wierd... what could cause this?
These cars don't have speedometer cables they are electronic. First thing I would do is check the connector to the sensor on the transmission. When it isn't making a good connection this will happen. I wish I could describe which sensor it is, mine has yellow on it and looks unique.

Hey guys I got a question about this sensor so I didnt want to make a new post. I am putting in a new transmission and everything seems right except for the cable that actually plugs into the sensor. It looks like it has a little metal piece that is spring loaded and you can push up and down, but then it has threads like it screws into something? I dont know if it is broke or if its just me, but I cant figure it out for the life of me.
