The overall goal of this study was to provide accurate technology assessments through highly detailed and transparent cost analysis methodologies that compare and contrast differences and similarities between these transmission systems. Based on that goal, FEV is hereby issuing an update to the previously released report dated 3/26/10. Minor revisions have been made to some of the electronic hardware and controls to more accurately account for all components as well as including required communication and feedback loops between these components with both highside and low-side electronic drivers. These updates are described below and are comprised of refinements in cost analysis results obtained as well as detailing the electronic control system differentials between the compared transmissions. This is done in an added table detailing the various solenoids, valves, sensors, wiring and various drivers that differentiate each unit.
