Abstract: A method of optimizing fuel economy and reduced noise and vibration levels in a vehicle includes one or more of the following steps: evaluating an engine speed and a speed of the vehicle, determining if the engine speed and the speed of the vehicle produces a noise level that causes a potential customer complaint, monitoring the noise level in the vehicle, calculating the engine operating condition that causes the noise level, determining if the noise level is above a threshold, adjusting an engine torque or a slip condition of a torque converter for optimal vehicle fuel economy if the noise level is at or below the threshold, and, if the noise level is above the threshold, adjusting the engine torque or the slip condition of the torque converter such that the noise level is at or below the threshold.
