Abstract: A transmission filter assembly utilizes a filter cartridge that slides axially with respect to the filter chamber. In normal operation, a spring pushes the filter cartridge into a position such that fluid flows into the interior of the cartridge, through filter media, and then radially out of the cartridge. If the pressure drop across the filter is excessive, the pressure forces the filter cartridge to slide to a position in which fluid bypasses the filter media. In this bypass mode, fluid does not flow into the interior of the cartridge and therefore has a very low tendency to dislodge previously captured contaminants. Two sets of tabs position the cartridge radially within the chamber. The two sets are separated axially to prevent tilting of the cartridge.
