We have plans of installing the valve body in a 7000 lbs Diesel truck that is making 1000 just in torque. The valve body does not require a computer, the 3rd gear check ball is .500 compared to the stock .250 ball. Because the valve body is billet aluminum and not cast, I designed the passages to have a smooth rounded arks for maxim flow. The valve body will not have any limitations, but the transmission will.
