ABSTRACT:
An apparatus for attenuation of fluid pressure pulses in a hydraulic system of an automatic transmission is provided. In one embodiment of the invention, a wave tuner is disposed within a fluid conduit between the transmission and a transmission fluid cooler. In another embodiment of the invention, a stand pipe is teed into the conduit with an open end of the stand pipe communicating with the conduit and an opposite closed end reflecting pressure pulses.
