The AW55-50&51SN / RE5F22A transmissions used in Volvos, Saturns, Maximas, and Saabs are spitting the planetary bushings out of the planets. One of the reasons this is happening is because of wear in the Aisin Warner cases. The bore for the outer race for the drive gear becomes worn and allows excessive movement in the gear train. See picture at right. We repair the case with a steel sleeve back to original dimensions.
