What is transbrake?

A transbrake is a device used in automatic transmission vehicles to improve drag racing performance. When engaged, the transbrake locks the transmission in both first and reverse gears simultaneously, allowing the driver to hold the car stationary while revving the engine. This builds up torque in the drivetrain, which can result in quicker acceleration off the line.

The transbrake is typically activated by a button on the steering wheel or shifter, and is most commonly used in high-performance racing applications where a quick and consistent launch is crucial. It is especially popular in drag racing, where fractions of a second can make a significant difference in the outcome of a race.

While the transbrake can be a valuable tool for improving performance on the track, it also requires proper setup and technique to avoid damaging the transmission. It is important to consult with a professional tuner or mechanic to ensure the transbrake is properly installed and used correctly.
