    The TCI competition valve body is built for quick elapsed times and maximum control in racing applications. Running the Ford C6 valve body through full manual operation allows quicker shift timing and higher line pressures than an automatic shift setup, which helps keep clutches from slipping under high load. The reverse shift pattern makes it a strong choice for bracket cars, monster trucks, and off-road competition vehicles where a transbrake is not legal or not wanted.

    • Fits Ford C6 automatic transmissions
    • Full manual operation
    • Reverse shift pattern
    • Allows higher line pressure to reduce clutch slip
    • Designed for bracket, off-road, and competition use
    • For 1969 and later applications, see part 421001
    • Part number: 421000
