    TCI 321400 - TCI Transbrakes

    TCI Transbrakes allow you to achieve maximum torque converter stall for quicker and more consistent reaction and 60-foot times. The transbrake acts in much the same manner as a manual clutch, preventing torque load transmission through the drivetrain before launch. Once the transbrake is released, power is transmitted immediately to the rear tires similar to a manual clutch but with the parts-saving advantage of the converter's shock-absorbing action.

  • Fixed line pressure with no chance of low line pressure condition
