Abstract
A filter unit for coupling in-line with a transmission fluid line is provided for filtering ferrous and non-ferrous particulate matter from the transmission fluid. The filter unit includes a filter element situated within a casing The filter unit has an annular magnet mounted on an end thereof. In an operational condition, the magnet is seated against an inner surface of the casing. As the filter becomes clogged, the filter element moves to a bypass position unseating the magnet from the casing. Fluid then bypasses the filter element but still flows around the magnet which continues to attract and trap ferrous particulate matter. A ferrous indicator flag may be positioned on the outside of the casing when the filter element is in its operational position and is released and falls away as a visual indication of a clogged filter element in the bypass position.
