Geartronics shift testing on a Lola F1 chassis with F3000 running gear. Testing could only be carried out under low load conditions because of the wheelspin on the rollers. If you look carefully you can see the gearbox actuator and throttle blipper operating during the downshifts. There's actually a lot more to gear shifting than simply operating the mechanical parts - the paddleshift is more of an engine control system than a gearbox control system, and the speed of the Zytek KV engine is being very carefully controlled during the shift sequence.
