ABSTRACT:
A transmission fluid filter comprising a metal base pan and a filter frame of thermoplastic construction which supports a filter medium in spaced relation to the base pan. Axially aligned openings in the frame and base pan received bolts for mounting the filter to a transmission housing. In accordance with the invention, a metal eyelet is crimped around a circumferential bead in the filter frame and has a central flat portion for absorbing the clamping stresses exerted by the mounting bolts remotely of the bead and crimp to permit high bolt retention stresses while relieving the problem of plastic creep and deformation.
