6 speed manual transmission (G56 not nv5600) 6.7 Cummins (seized). Showing 134742 miles.  I bought this pickup for the bed, so I do not know a lot about it. What I do know is that it is pretty rough.  The engine reportedly lost oil pressure and subsequently seized up. There doesn’t appear to be a strait body panel on the pickup.  The windshield is cracked.  The frame appears to be strait.  There is a pack rat residence between the hood and the insulation.  The previous owner reports no issues with transmission, clutch, ecm, transfer case or rear end. The front tires hold air long enough to get it loaded on a trailer. Not interested in parting out at this point.  7eight5 four5four eleven4four
