Default Trans Brake or two step?

This is kinda out there but, can a 4T65E be programmed for a trans brake?
Quote:
A transbrake is a device which allows a car to remain stationary even when the motor is under power. It works by placing the transmission in 1st gear and Reverse at the same time. Since both gears have the same ratio, but it opposite directions, the car cannot move. The transbrake can be released with a button, which releases the Reverse gear.
and

How about a two step then to go with the trans brake?
Quote:
A two-step is an electrical ignition device that will "cut out" cylinders at random, after the engine rpm tries to exceed a certain point. This is basically a rev-limiter. The driver can set the low-side rpm of the two-step to be his launch rpm. With this, the driver can activate the two-step, and press the gas to the floor without over-revving the engine. You can recognize a two-step by the uneven Pop-Pop-Pop of the motor. Release the two-step, and the motor is unleashed, the throttle already wide open.

I know the GM Racing Tranny has a trans brake. I'm trying to find the link to it.... I'm pretty sure that you have to modify the case etc.

I"m not sure I like the 2 step idea.....that sounds like a good way to blow something up.

Trans brake not required below 800hp
Yeah but it would be cool combined with a 2 step
