When it down shifts, the throttle automatically blips as well, so it's smooth as well but not as smooth as an auto. The SSG is a littel crude I would say, worse than the selespeed but the SMG on the E46 M3 is much better having tried both. As it is, I am on auto mode most of the time <img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" class="smilie smilie--sprite smilie--sprite1" alt=":)" title="Smile    :)" loading="lazy" data-shortname=":)" /> 2) Yup, the SMG boxes are made by Getrag and very similar to the manual gearboxes, with the additional hydraulic actuator. Clutch plate is also similar to the manual ones. 3) Well DCT, offers better efficiency compared to auto boxes (now that's the rage in Europe) and smoother plus faster shifting speeds compared to SMGs. Plenty of VWs and Audis are already equipped with DSG, and I believe in the near future BMW will also offer DCT in the lower range models, as they aspire to lower the CO emission in the product range. This is a nice review of the Z4 and the difference between the Z4 DCT and E92 M3 is elaborated.
