What is trans brake?

A trans brake is a racing component typically found in high-performance automatic transmissions, particularly in drag racing vehicles. It allows the driver to lock the transmission in first and reverse gears simultaneously, creating a "neutral" state that allows the engine to rev up while the vehicle remains stationary.

When the trans brake is engaged, the vehicle can build up torque and power without moving forward, which can help the driver achieve a better launch off the starting line. This can be especially important in drag racing, where a fast and consistent launch can make a significant difference in the outcome of a race.

Trans brakes are typically activated through a button or switch located on the steering wheel or dashboard. Engaging the trans brake effectively puts the vehicle in a holding pattern, allowing the driver to bring the engine up to optimal speed and boost the RPMs before releasing the brake to launch the vehicle down the track.

Overall, a trans brake is a valuable tool for drag racers looking to maximize their vehicle's performance and achieve faster and more consistent launches off the starting line.
