While transmissions of three and four-speed automatic transmissions were quite unpretentious in terms of oil quality, the filter played a secondary role. These were simple devices with a stainless steel mesh. Such filters were simply washed periodically, and there was no need to change them. After the modernization of automatic transmissions, pollution increased and it became necessary to change the filter.

The usage of the FEBI BILSTEIN brand Parts Kit, automatic transmission oil change

The optimal solution was to insert synthetic double membranes into plastic housings, make them easy to remove and change with every oil change. Further modernization of filters was associated with their adaptation in size (different for SUVs and cars), there were main lines, magnetic for screening out metal particles, with different mounts. Almost every model has its own filters with variations. Remember that not replacing a clogged filter in time can damage the entire automatic transmission. Actually, the kit is used for such needs.
