    Transbrakes

    In the world of competitive drag racing, consistency is a major key to success. Understanding this universal truth, TCI has developed the GM 4L80E Transbrake Valve Body for radical street and all-out racing applications. The TCI valve body contains no additional external components to hinder installation and is guaranteed to provide more aggressive starting launches,quicker reaction times, improved consistency and all-around better ETs. Once installed, the TCI GM 4L80E Transbrake Valve Body modifies your transmission into a full manual shift, reverse pattern unit with an impressive Pro Tree trans brake feature. It also retains torque converter clutch engagement in overdrive and still allows lockup in lower engine rpm. Best of all, this performance valve body from TCI does not require the use of an aftermarket transmission controller or deep transmission pan to facilitate operation of the 4L80E transmission. The new trans brake valve body achieves maximum torque converter stall and quicker reaction times. This is due to the trans brake action which prevents an engine's torque load from being transmitted through the drive train prior to the launch. Once the trans brake is released, the power is transmitted immediately to the rear tires in much the same manner as a manual clutch but with the parts saving advantage of the torque converter's shock absorbing action. This new development in drivetrain technology is guaranteed to deliver better consistency andacceleration on the street or at the track.

    Maximum Torque Converter Stall

    TCI Transbrake Valve Bodies deliver quick and steady reaction and 60-foot times by countering engine torque load (transmission through the drivetrain) prior to launching. When released, these valve bodies immediately transmit power to the rear tires. When engaged, the transbrake prevents forward or backward roll while pressing on the accelerator, allowing the engine to turn rpm as high as the torque converter stall.
