ABSTRACT:
The invention provides a tool for removing a lance or indentation in the retainer of the planetary of an automatic transmission and for forming a lance in the retainer after replacement of friction or steel plates. The tool includes a circular base having a raised curved exterior section and a raised curved interior section spaced apart by a gap. The interior section has an indentation in the outer wall. A first insert fits within the gap having a curved front wall facing the interior section and also having the same curvature thereof. A second insert is fittable within the gap having a protrusion capable of registering with the indentation. Means for exerting inward compression between the first and second inserts against the interior section are provided to remove a lance, in the case of the first insert, or to form a lance in the case of the second insert.
