I had a similar annoying transmission issue with my 550. There are two SIBs out that address transmission programming issues and the fix for both problems is the same software update. Often BMW will not update your car upon request unless you describe the exact problems on the SIBs (sometimes service advisor's don't know about the SIBs) so do a search for transmission surge SIBs, take a copy of the SIB in to BMW, tell them your car does exactly what is described in the SIB, and get you car transmission software updated. Bottom line: what you describe is likely a programming issue and can be changed with an update.
