Try the transmission control module. It may need to be reprogrammed (a simple fix by a GM dealer). Also you may wish to have the electrical tested. The coolant light is typically for the engines cooling system however trans fluid also can run low and overheat without a trans fluid heater or cooler (typically used in extreme climates). Best of luck!
