Converter. Trans brake questions.

When you foot break a car the power is going to the wheels, and the only thing stopping it is your breaks. The chassis, suspension, and tires are loaded. With a transbrake the power stops at the trans when the transbrake is engaged. There is no power to the driveshaft at all, so the chassis, suspension, tires are all slack until you release the button. You can certainly see how this requires a completely different setup. Every car and setup is different, so there is no... "this one is better".
