I think I posted it earlier this year, I had a 2 second delay in very cold weather when shifting from reverse back to drive after backing out of my garage in the morning. I found out there was a technical service bulletin from BMW that required the transmission computer to have specific memory locations programmed like a patch (not a s/w upgrade but to write new factory parameters in memory).
Dealier applied this and the delay went away - this fix applied specifically to the VIN# and model year - GM steptronic, June 03 manufacturing date.

This may be not at all related but I would check the TSB's.
