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.

A power steering assembly is provided that enables a secure, simultaneous connection of supply and return hose assemblies to a steering gear. The assembly includes a mounting bracket having an aperture through which one of the hose assemblies extends and a notch configured to receive the other hose assembly. The bracket is deformable such that the other hose assembly can be secured within the notch after insertion. The pressure and return hose assemblies include either a connector having opposed shoulders on either side of the bracket or are deformed to create beads on either side of the bracket to restrict movement thereby eliminating welds or brazes. Each of the hose assemblies further includes a groove formed to receive a seal. These grooves on the external portion of the hose assemblies reduce costly machining on the steering gear head.
