    Read this thread, it has the TSB number in it. http://www.gmtruckclub.com/forum/sho...ce+Stabilitrak
    Thanks for the tip. I'll check the codes and see if they line up with a TPS. The service bulletin (11273) only goes back to 2008 and mine is a 2007. And I've never seen the Reduced Power message or felt the effects either - just Stabilitrak and Traction Control. I'm wondering if it might be something else.

    No prob, Alan, actually, I thought I was answering the op, he has 2011. Your right, the 2007 Silverado is a different truck and the TSB would not apply. But, other than the Reduced Power message, your description is the same.
