Duramax Fourth Generation: 2007.5-2010 (LMM)
I have a 2008 Chev Silverado 2500HD and getting the P0658 code. First time yesterday. Cleared code and it ran fine for 80 miles, now it's stuck in 1st gear. When shifting to D or R, the transmission jolts. Any thoughts? Sounds very similar to your issue you had. Did you have any more issues...
