Question I have an 87 grand am se 2.5l tech4 engine with a 5 speed trans It has an electric speedometer and a digital odometer. The speedometer and the shift light work intermittently. All other gauges in the cluster work. I have changed the vehicle speed sensor in the trans. I still have the problem. Can you give me any ideas what could be causing this???

Reply You might have an intermittent problem in the speedometer or defective vehicle ECM. Angelo Silverado Auto Service
