14 is located automatic transmission fluid atf drawn from a fluid sump through hole 26 flows through the filter media 22 and exits the filter assembly 10 though exit tube 14 due to suction produced at the entrance of a hydraulic pump which communicates with the exit tube 14 fig3 and 4 show that a width 23 around the periphery of filter media 22 is supported on the lower flange 18 and is overlapped by the upper flange 16 the subassembly 20 is overmolded such that the ribs 24 are interlocked with the filter media 22 by strips 30 and buttons 32 the ribs and strips forming a tray or grid located at longitudinally spaced locations along the length of each rib 24 and formed integrally with each rib are strips 30 which extent laterally and interconnect the five ribs forming the tray which supports the filter media 22 also located at longitudinally spaced locations along the length of each rib 24 and formed integrally with each rib are buttons 32 each button located at the intersection of each rib 24 and each strip 30 each button 32 is spaced from the corresponding strip 30 by a vertical gap directed along the depth of the ribs the filter media 22 is located in the gaps and overmolded with the tray or grid each strip.
