uncleben77 posted a topic in 1999-2013 Silverado & Sierra 1500Hi all. I just converted from '94 ford to Gmc. Love my new Denali and loved my old ford too. But is there a better way to search parts other than the gmc parts for interchangeable years instead of looking up several years to see if the part numbers are the same? I found parts that fit other years but if I go to like 2008 those part numbers are the same too but we're not listed under 2011. Like under 2011 it would say fits these vehicles from 2011-2013 but if I change vehicle type to 2008 it had same part number too. I'm looking for back up sensors and interior molding parts like for center console. Same part number for the 2008 Yukon Denali but wasn't under similiar vehicle list when the 2011 was chosen. I have some broken part issues and if I had a full scope of the years covered like 2007-2013 I can search junk yards if they have those years in their inventory. I think, but not sure some parts will fit from 2008-2013 Sierra, Silverado, Yukon, Escalade and Denali options. Any help would be appreciated. Thanks
2011 hd 6.0. Rpm fluctuates at 18 to 2000
JDC posted a topic in 2000-2014 Silverado & Sierra HDI just purchased a 2011 gmc 2500hd Denali with 157000 miles on it. When the rpms are just below 2000 the needle spikes to 2000 and drops back, as if surging. It downshifts fine. If you try to gradually accelerate at that point it shudders as if in to low a gear. I have not tried pulling anything with this truck yet, but wanted to get an idea whether or not I have a serious problem or not. I took it it to a dealer to have a diagnostics ran on it and the tech couldn’t get power to the tester, so before I tackle that issue I wanted to see if I had a major issue. According to some of these forums this looks to be a issue on a lot of newer trucks. any experience with this issue would help. Thanks
