Rrecently bought a 2009 Saturn XR. While driving I noticed when facing a light grade under 2000 rpm there is either a misfire or a transmission shifting problem . This problem ocurrs when we are at highway speed and encounter the uphill. As we head up the grade the Outlook seems to start skipping like crazy. Once we top the hill to a flat or downhill the problem stops. It's very difficult to determine if this is a transmission shift issue or a misfire. Has anyone else experienced this issue and if there are any tech bulletins on the issue and what fixed the problem. - thanks
