![]() If the Co-Pilot is installed on a stock valve body then the stock valve body does not have the ability to produce or handle the higher line pressure that is being commanded. The TCM presents a problem, the TCM does not have the ability to command the line pressure that the transmission needs to be able to hold the higher HP levels. ![]() That being said the valve body must be commanded by the TCM to be able to produce the higher line pressure. The valve body allows for increased pressure to the clutch packs which provides for higher transmission power capacity. Understanding what our performance valve body does vs our Co-Pilot does can be confusing so this is a brief description. When the valve body is installed with the addition of the ATS Co-Pilot transmission controller your stock transmission will hold power levels of 200HP over stock. When our performance valve body is installed in a good stock transmission you can expect the transmission to hold on average an additional 100 and upHP. The accumulator plate is made of high-grade material to compensate for the additional pressure that the accumulator pistons and springs exert during heavy power situations.Īlso, the ATS 68-RFE valve body can be installed in a stock transmission for increased transmission capacity. The accumulator piston seals have been redesigned to ensure hydraulic pressure integrity. Hydraulic oil flow is ported to certain clutch packs where additional pressure is needed. Because of the sensitivity of the hydraulic circuits, we heavily modified many areas of the valve body. This means that the shifts from gear to gear must be timed perfectly thereby releasing and applying a friction clutch to achieve an flawless shift. The 68-RFE uses a non-synchronous, clutch-to-clutch design. The valve body is considered the nervous system of the transmission the valve body is responsible for converting the electrical signals from the TCM into hydraulic actions.
