<Tr> <Td> DL501 </Td> <Td> Longitudinal </Td> <Td> 7 </Td> <Td> 600 </Td> <Td> Wet </Td> </Tr> <P> The internal combustion engine drives two clutch packs . The outer clutch pack drives gears 1, 3, 5 (and 7 when fitted), and reverse--the outer clutch pack has a larger diameter compared to the inner clutch, and can therefore handle greater torque loadings . The inner clutch pack drives gears 2, 4, and 6 . Instead of a standard large dry single - plate clutch, each clutch pack for the six - speed DSG is a collection of four small wet interleaved clutch plates (similar to a motorcycle wet multi-plate clutch). Due to space constraints, the two clutch assemblies are concentric, and the shafts within the gearbox are hollow and also concentric . Because the alternate clutch pack's gear - sets can be pre-selected (predictive shifts enabled via the unloaded section of the gearbox), un-powered time while shifting is avoided because the transmission of torque is simply switched from one clutch - pack to the other . This means that the DSG takes only about 8 milliseconds to upshift . In comparison, the sequential manual transmission (SMT) in the Ferrari F430 Scuderia takes 60 milliseconds to shift, or 150 milliseconds in the Ferrari Enzo . The quoted time for upshifts is the time the wheels are completely non-powered . </P> <P> The direct - shift gearbox uses a floor - mounted transmission shift lever, very similar to that of a conventional automatic transmission . The lever is operated in a straight' fore and aft' plane (without any' dog - leg' offset movements), and uses an additional button to help prevent an inadvertent selection of an inappropriate shift lever position . </P> <P> P position of the floor - mounted gear shift lever means that the transmission is set in park . Both clutch packs are fully disengaged, all gear - sets are disengaged, and a solid mechanical transmission lock is applied to the crown wheel of the DSG's internal differential . This position must only be used when the motor vehicle is stationary . Furthermore, this is the position which must be set on the shift lever before the vehicle ignition key can be removed . </P>

How do i know if i have a dsg transmission
