scca? racecar transmissions

[bucks69]

A friend and I were discussing the transmission that these road racers use and it is a lot like the infinity G35 we had that you put it in drive then bump it to manual.. Do they make a controller like this for the 4L80E or do they use a special transmission to get the type of shifting performance they want.. I know the systym looks simple but I believe it to be very intricate... Any brand type/manufacturer or just any info would be greatly appreciated
