Message: <blockquote data-quote="M3ac" data-source="post: 461256" data-attributes="member: 21378">Yes you are absolutely right, thanks for the explanation. I googled it and found out that BMW calls it SMG which stands for "Sequential Manual Gearbox" which is an Electrohydraulic manual transmission.This type of semi-automatic transmission system, which uses an automated clutch unlike conventional manual transmissions where the driver operates the clutch. The clutch is controlled by electronic computers and hydraulics. To change gears, the driver selects the desired gear with the transmission shift lever, and the system automatically operates the clutch and throttle to match revs and engage the clutch again. Also, many such transmissions operate in sequential mode where the driver can only upshift or downshift by one gear at a time.Depending on the implementation, some computer-controlled electrohydraulic manual transmissions will automatically shift gears at the right points (like an automatic transmission), while others require the driver to manually select the gear even when the engine is at the redline. Despite superficial similarity, clutchless manual transmission differ significantly in internal operation and driver's 'feel' from manumatics, the latter of which is an automatic transmission (automatics use a torque converter instead of clutch to manage the link between the transmission and the wheels) with ability to signal shifts manually.Could not find SSG though...but its ok.</blockquote>
