The TCI TH400 transbrake kit lets the engine build to maximum torque converter stall for quicker, more consistent reaction times and 60-foot times. The transbrake prevents engine torque from reaching the drivetrain before launch, so the vehicle holds in place while the engine climbs to stall speed. When released, power is transmitted immediately to the rear tires. This kit uses a reverse shift pattern with safe neutral and includes the solenoid.
