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
