Is there a standard transmission that comes with the new 2012 BMW Z4 Sdrive35iS? I'm looking at getting a new Z4, and when I do a build online, it doesn't even let me specify transmission type. I hear there are 6 speed automatic transmissions, 7 speed DCT automatic transmissions, and even manual options, but can't figure out how to work any of them into a build. My dealer showed me a vehicle inquiry on one that another dealer had, and even this report didn't list the transmission type, although it listed all the options. What is the default transmission that comes with the 35is?
