2008 Chevy HHR check engine light
My 2008 Chevy HHR's check engine light is on. The codes indicate a problem with the transmission. Replaced the TCM and took it to 2 transmission shops. They checked the codes and then checked the transmission. They found no problems. What do I do if check engine light itself is malfunctioning or there is a problem with the ground? I need to get the car inspected, but cannot due to light coming on.
What trouble codes do you have? To test the light ground circuit you need a scan tool to command the light off. HTH. -Jim
