1 to 2 shift problem with no overdrive
2007 sierra 1500 classic crew cab z71
Hey guys, My truck runs first gear up to 3k or 4k before it shifts into 2. it will shift around 2800 rpm if i let off the pedal. another issue is it wont shift into overdrive. A friend checked the codes and he said no trans codes are being generated. I did drop the pan and changed the shift accumulator but that did nothing to fox my issue. Any suggestions?
