Trans Brake
Activated by electrical solenoid control, a trans-brake simultaneously engages the first and reverse gears, locking the transmission and preventing the input shaft from turning. This allows the driver of the car to raise the engine rpm against the resistance of the torque converter, then launch the car by simply releasing the trans-brake switch.
I believe the Rossler trans brake that just came out locks two forward gears instead of 1st and reverse.
If so now I understand what the big deal is when negoating a race between two auto cars with the trans brake.
