Anyone know the possible cause or had this issue. From a dead stop the trans slips for a few seconds then all of a sudden grabs. There is a sort of clunk when it grabs also. It happens intermittently. It will go days without doing it then it will slip several time when we are out and about. Dealer says bring it in but they have no idea what could be wrong and said if it is intermittment it may be hard to diagnose.

I have never heard of any such issues... Sometimes mine jumps from a dead stop, but it is not a transmission slip issue, I think it is more-so kinks in the 'fly by wire' system.

Actually I bought the GM certified for 100000 when we got it. They found internal issues with the trans. I got it replaced for free.
