Default How will Launch Control work on an automatic?

As the title is self explanatory, I was just using my MN6 in LC and couldn't figure out how they would get an auto to work the same way? Any thoughts? Thanks....

The transmission is computer controlled. Dial in a RPM. When the rpm is reached the transmission engages .

My guess the shifting schedule is electrically controlled. I would think selecting launch control will allow the engine rpm to reach a computer setting, (arming the launch). Activating will computer modulate the auto clutch to apply this stored power of the drive system. A modern form of high engine rpm and then dropping into drive, without the drive line abuse.

Interesting. Never thought about those ideas but since it will be all computer controlled what could go wrong, right?

I think it more likely it would be upon brake release.

I can see that.However you are limited by torque converter lock up. At whatever RPM the converter locks up would be your launch limit.
My theory is based on automatics used in Drag Racing. I respect your opinion.

You are correct it's limited to the stall rpm of the converter, I think stock 6L80 is 1,600, so unless they adjust that in some way, launch would be just like todays auto vette and the only influence on launch would be the state of traction control
