I don't know about "everyone else's" but I have a friend with an Avalanche and it does it. My 03 H2 did it, my 05 does it, and a friend with a Denali had this same trouble.

It doesn't do it all the time, but no one will ever fix it without a code, so you'd have to keep taking it in x1billion to get them to actually take it apart. I have had it get slightly low on tranny fluid and when you start it up first thing in the morning it will lurch forward a little while it's in park. It's done that two or three times now. No one can tell me where the fluid is going either. I just passed 80,000 miles on my H2 and haven't had it throw a tranny code yet. It's getting close to needing a rebuild though, and I think I'll have it beefed up when it's time. I hope this helps. It's not a technical answer, just another owners experience.
