I found another GM software issue, unable to clear transmission codes on allison transmission . I was working on 2004 silverado hd 6.6 duramax and I replace the pressure solenoid and after I finish replacing the solenoid I want to clear the codes and it couldn't clear the code I try 5 times, I reboot the tablet and nothing code cannot clear, I connect the snap on verus and it clear on the first try.
