It's on the Turbo Forum archives how to.
1st and reverse gears are engaged at the same time via the shift solenoids.
Pretty sure Dodge Did the same with the Demon.
A Pro Tree Transbrake is actually a very sophisticated layout.
Allows .001 second - 1 microsecond launches full power stored instant released.
The driveline is not shocked so hard.
Driveline in preload setting when the button released.
So I hear the ideal way to launch with a 6l80e is with a converter and launching at a mere 1900rpm. I mean you can do your own research on the subject and come back here and tell me how right I am. It is 2 extra gears and starting off with 4.02:1. And that means we can do things a little differently.
