High horsepower engines require modifications to their power train to prevent the transmissions from failing. A stock transmission has limited clutch material; by reworking the stock valve body to increase the amount of clutch apply pressure, the holding ability can be improved.
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 converter oil evacuation time for quicker clutch apply time. Solenoids are pre-tested 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 is required 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.
