  • Patent number: 8627928
    Abstract: The present invention provides a fluid displacing transmission filler having a blow molded, foam filled body. The body or shell of the filler is blow molded in a mold which shapes it to conform to internal surfaces and other features, such as gears and shafts, of a transmission. Then, the blow molded filler body is filled with closed cell foam. The resulting transmission filler is lightweight, achieves a maximum volume for an available space within a transmission and is essentially impervious to failure and filling with fluid because the closed cell foam does not significantly absorb transmission fluid.
