High horsepower engines require modifications to their power train to prevent the transmissions from failing. A stock transmission has limited clutch material and its holding ability can be improved by increasing the amount of clutch apply pressure by reworking the stock valve body. New valve designs, new springs, oil port sizes, new governor piston dimensions and adjustments have been made. Larger ports increase flow rates which cools the oil and reduces convertor oil evacuation time for quicker clutch apply time. Solenoids are pretested as is the complete valve body prior to shipping.We also have 2nd gear lock up available so you can use 2nd gear for some serious engine retarding. A TorqLoc switch will have to be used to activate this function.If you have an extremely high horsepower engine we can preset the valve body for pressures up to 180 psi! Normal applications are usually set for 100 psi.Each valve body is tested on our Answermatic 2000 tester before shipping.
