| Abstract: | The noise measurements of some five speed automatic transmission were made.The measurements were based upon the order analysis function,which was provided by the PAK vibration and acoustic measurement system.The sound pressure levels under different speed were obtained.The results provides a helpful reference for identifying the transmission noise origin. |
