Before searching for answers, I thought I would have to accept what I was being told about the “adaptive transmission”. I experience most if not all of the issues above, most of the time. Although it brings me no comfort to know others are suffering with the same issue, it is good to know it is not me. So much so that after only 2000km, I am looking forward to an opportunity to get rid of this truck. Had I known when test driving it, or had I been told this would be an on going issue, I WOULD NEVER have purchased it. Unacceptable. As a Past Silverado owner, loved every time I got behind the wheel, now seconds after putting that thing in drive it is like a nothing I have ever experienced, constant shudders, jerks, lugging and jumping. all I can hope now is that someday, a fix will come out, that and I hope the service Dept doesn’t hide when the seem me coming every week. A real shame because I was so looking forward to this truck and now I can’t stand to drive it
