This 700R4 Valve Boy is a Full Manual Operation that retains Lock-up Capability. Features Reverse Shift Pattern.
The competition valve body was designed for maximum performance and quick elapsed times in racing applications. By controlling the valve body only through manual means, quicker shift timing and the ability to run higher line pressures than possible with an automatic shift transmission are achieved. Higher line pressure makes it more difficult for clutches to slip under high loads. TCI Full Manual Valve Bodies are an excellent choice for bracket cars, monster trucks and virtually any off-road competition vehicle where a transbrake is either not legal or not desired.
