I thought some of you transmission (gearbox) guys would enjoy this

Look at how small the input shaft is.

I was hoping to see the mechanism inside the sequential shifter.
That was the little piece of magic that I found fascinating.

In that box it's electronics that controls the air flow to move the "shift shaft;" can't find the name at the moment.

Look at the top picture on Page 57. The forks are moved by the circumferential grooves of that shaft which is why it has some diameter, versus the internal rails that move linearly in a T56.

At it rotates, it moves the shift forks into and out of position.
