Be happy to leave positive feed back Mike, but as of yet I`ve heard nothing from anyone.

Expert:  Mike Kelly replied 4 years ago.
Sorry it took so long for someone to get back to you on this.
From what you are describing the issue that you are having is the vehicle speed sensor is starting to fail on the vehicle and results in the light coming on and the other symptoms. The reason that it goes back to normal at times is because the sensor has not completely failed yet. I am also a warranty inspector and have inspected this issue on these vehicles many times as it is common. To correct the problem the speed sensor is replaced.

Can you please tell me where speed sensor is located?

Expert:  Mike Kelly replied 4 years ago.
The speed sensor is mounted on the side of the gearbox,held on by one bolt and one electrical connector.
