TCI Trans-Brake Valve Body Kits 221500

Our Transbrake Series allows you to achieve maximum torque converter stall and provides for quicker and more consistent reaction times and 60 foot times. This is due to the Transbrake action which prevents an engine's torque load from being transmitted through the drivetrain prior to the launch. The Transbrake acts in much the same manner as a manual clutch. Once the Transbrake is engaged the vehicle can neither roll forward nor backward, and as you press on the accelerator the engine can RPM as high as the torque converter stall. Once the Transbrake is released, the power is transmitted immediately to the rear tires the same way as with a manual clutch, but with the parts saving advantage of the torque converter's shock absorbing action.Fits GM TH400, 1965 & later. Has reverse shift pattern.
