A two step is a rev limiter. As an example, in my car the converter will stall to around 5,500 rpm. I have the 2-step set to 2,600 rpm. So when I stage the car and hold the trans brake button, with the gas pedal matted to the floor, the engine is rev limited to 2,600 rpm. When I release the trans brake button, the converter flashes to 5,500 rpm and off I go.
