I think it doesn't really matter, they use an automatic trans, convert it to full manual, then back to an auto shift be it air or electric solenoid. Sounds kind of funny, but does the same thing the auto did, just more consistent than hydraulic circuit shifting or manual ratcheting. Saying you can use an automatic trans and you have to shift it manually doesn't really make sense.
Stick shifts are more fun, just not as consistent as a glide that shifts once at exactly the same RPM every time.
You still got to drive it straight, still got to hit the light, and still got to run the finish line to be consistent, anything that does any of those things is illegal.
Now, in a corner carver pro touring/road race style, I'd take a stick shift every time, but then I'm in the wrong thread.
What about a lenco with a bruno drive? You don't need a clutch to launch or shift but still have to shift multiple gears, another gray area, but awesome. One of my uncles used to race a Lenco in a green Camaro back when I was a kid, that thing was cool, we called it the green hornet. I was pretty little, maybe 5, I'll have to ask him or my Dad if that had a clutch or a converter.
