Hello,
My 2005 GMC Yukon XL 1500 Autoride 4x4 5.3, is intermittently pulling OBD2 scanner code p2671. It pulls this code twice. The only symptom is right before code illuminates, when driving between 40-50 mph is the transmission jumping between 3 and 4 gear. This SUV runs great! Transmission shifts smoothly at all other speeds. I have researched for several days with only very confusing information. Can anyone help?
