2005 645 also impacted by this?

I have a 2005 645 convertible with the SMG transmission and have a similar issue. THe hesitation followed by surge only seems to happen when the vehicle is cold and shifting from first to second gear. Once warmed up, it completely disappears. I had thought that it was an engine issue, not transmission. Anyone else having similar problems?

I had my trusted independent shop in West Chester, PA (Bimmerworks) Check it out. He found nothing wrong.

Do you guys happen to know if the 645 is also impacted by this issue? We essentially have the same engine / transmission combo as the 545.
