The effect of lockup and extended gear ratio range is also investigated. The assessment of these vehicle variables on fuel economy and performance is determined by using the Transportation Systems Center's vehicle simulation program, VEHSIM, which predicts fuel economy and performance for vehicle parameter changes. The results indicate fuel economy and performance trends which can be used to project future improvements
