Calling Transmission experts: Slow upshift after tranny flush?
Dealer flush my transmission with the latest spec Shell fluids but it "feels" like my upshifts are now slower? Is it possible that they under or over filled the tranny fluids and causing the torque convertor to slip?

Definitely a possibility. I would try resetting the computer that manages the transmission and see if that helps. There are posts on how to do it but i do not have the link handy.

I was under the impression that the reset procedure that you referenced doesn't work for C63's, but I'm not sure about E63's.

It easy to have not filled the trans properly. It is a absurd procedure. If you think that they might have take it back and have them check the fluid level.
This will require you to drop it off for a while because the fluid has to be checked at a pretty low temperature. Probably best to drop it off at night and let them have it cold. Also the computer will store codes if it has slipped at all.
What dealer did you take it to? In seattle?
