2008 Chevy HHR check engine light

Asked by Apr 06, 2017 at 04:49 PM about the 2008 Chevrolet HHR LS

Question type: Maintenance & Repair

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
