Improve the clutch holding capability and shift pattern of your 68RFE automatic transmission by upgrading your valve body with this unit from ATS.
The valve body is considered the nervous system of the transmission; the valve body is responsible for converting the electrical signals from the TCM (Transmission Control Module) into hydraulic actions. The 68RFE uses a non-synchronous, clutch-to-clutch design. This means that the shifts from gear to gear must be timed perfectly thereby releasing and applying a friction clutch to achieve a flawless shift. Because of the sensitivity of the hydraulic circuits, ATS has heavily modified many areas of the valve body. Hydraulic oil flow is ported to certain clutch packs where additional pressure is needed. The accumulator piston seals have been redesigned to ensure hydraulic pressure integrity. 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.
Also, the ATS 68RFE valve body can be installed in a stock transmission for increased transmission capacity. When this performance valve body is installed in a good stock transmission, you can expect the transmission to hold on average an additional 100+ horsepower. When the valve body is installed with the addition of the ATS Co-Pilot transmission controller, your stock transmission will hold power levels of 200 horsepower over stock.
Understanding what ATS' Performance Valve Body does versus the Co-Pilot does can be confusing, so this is a brief description. The valve body allows for increased pressure to the clutch packs, which provides for higher transmission power capacity. That being said, the valve body must be commanded by the TCM to be able to produce the higher line pressure. The TCM presents a problem, as it does not have the ability to command the line pressure that the transmission needs to be able to hold the higher power levels. 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. Because of these two issues, you only get partial line pressure gains when only the performance valve body or the Co-Pilot is installed separately.
Because of the complexity of the 68RFE electrical and hydraulic system, in order to get the full effect of the valve body, the Co-Pilot should be installed in addition to the valve body.IMPORTANT NOTES:
