Its basically a manual but dual clutched, almost like 2 gearboxs in one. 1st 3rd 5th on one shaft with a clutch and 2nd 4th and 6th on the second shaft with a clutch. if its in one gear, the next gear is locked and loaded ready for the shift. Same as a dsg or pdk. It does have some trick electronic diff stuff in the car too which taps a brake calliper to divert power, it could well do this whilst on boost so need the pump? no idea tbh.
