Gentlemen... My duramax likes to shift hard from 1-2 when cold or not fully warmed up. I always feather the throttle in anticipation, sometimes it seems worse than others, but it's incredibly annoying. It's not ridiculously bad, but it's not as smooth as it should be. I think it's probably just the programming, I don't think I've destroyed anything internally, but has anyone had a similar experience? Will a re-flash help? Is it my frigging Bullydog that's doing it? Will my tranny self-destruct?
