Description

TCI Transbrake Valve Body for '91-'96 4L80E. Achieves maximum torque converter stall, quicker and more consistent reaction/60-foot times by preventing engine's torque load transmission prior to launch. Acts like a manual clutch, allowing engine RPM to torque converter stall. Upon release, power is immediately transmitted to rear tires, absorbing shock. Features Reverse Shift Pattern.
