Our competition valve body for maximum performance and quick elapsed times in a racing application. By controlling the valve body only through manual means we can produce quicker shift timing and are able to run higher line pressures than possible with an automatic shift transmission. Higher line pressure makes it harder for clutches to slip under high loads. Remember, with a full manual you will have to make every shift, for these units do not shift on their own. A great choice for bracket cars, monster trucks, and virtually any off-road competition vehicle where a Trans-Brake is either not legal or not desired.
