Dual clutch transmissions are not really more complex than torque converter automatics, they're really just 2 manual transmission molded together plus 2 clutches versus many clutches or bands in torque converter autos. They can very quickly shift up or down if an appropriate gear has been preselected, but if not, it might take a while and will be very noticeable. Basically, they are really good for uninterrupted acceleration but when the speed has to vary a lot like in traffic, they get confused. Modern autos like ZF 8spd are better in this regard because in each gear, they have to disengage and engage very few clutches to go up or down a gear. It's as if they were like 3 clutch gearboxes which would have 2 gear preselected instead of only one
