Pontiac Grand Prix Intermittent Odometer

mdragemdrage Member Posts: 1
I have a 2003 Pontiac Grand Prix with an analog odometer. It is working intermittently. When it works, both the trip and overall odometer work. Occassionally the odoters wil reverse for a couple of tenths before going in the normal direction. I took the vehicle to a Pontiac dealership, but they had no idea where to begin. Any suggstions?

    My 06 Pontiac Gran Prix speedometer started acting strange? It jumps up to about 40 when you start out driving and then it reads about? 110MPH when your going between 60-75? Is this a sensor problem? IF so where is the sensor located? Any help with this problem would be appreciated. It also started shifting hard but I haven't check all the posts yet for a hopeful solution for that. Thanks, Warren
