I have a 2008 GMC Acadia, and the service traction system light came on and has been on. The condition has gotten worse in the last couple weeks, it was just coming on periodically, now its on all the time and at times the transmission will even short shift, as of today it acts as if it wants to stall and not have any power steering. The check engine light is on also and the code for that is chamber one and two for o2 sensor, just wanting to know what's wrong with it. Any info would be appreciated thank you. Shaun.
