TCI Circle Track Valve Bodies
Internal Control Powerglide Valve Body
TCI's next generation in circle track valve bodies. These reverse pattern, internal control valve bodies eliminate the hand-operated ball valve pressure control, by replacing it with a clutch-pedal control that controls line pressure internally and automatically. The reverse shift pattern allows you to up shift without hitting neutral or reverse. It'll even operate smooth enough to allow you to drive on and off your trailer.
