Claim Text:
1. A transmission comprising: an input; an output; a first intermediate shaft; a second intermediate shaft; a first clutch configured to selectively couple the input to the first intermediate shaft; a second clutch configured to selectively couple the input to the second intermediate shaft; a first coupler configured to selectively establish a power flow path between the first intermediate shaft and the output; a second coupler configured to selectively establish a power flow path between the second intermediate shaft and the output, wherein the transmission has a first natural frequency when the first coupler is engaged and the second coupler is disengaged; and a controller programmed to command an oscillating actuator position of the second clutch with a dithering frequency to dampen resonance at the first natural frequency, wherein a ratio of the dithering frequency to the natural frequency is at least 2.5.
