Replace a worn or damaged servo piston during a properly diagnosed transmission repair or rebuild. This component is intended for the matching servo configuration, not every transmission within the listed families.

Before ordering, compare your original piston, servo cover casting and component dimensions. Transmission identification alone does not confirm fitment, as these transmission families use multiple servo sizes.

Inspect related servo components during installation and follow the applicable transmission service procedures. A replacement piston is not a guaranteed remedy for shifting problems caused by other worn or damaged components.

Lubegard ATF Service Note: Consider a Lubegard ATF product only when its specifications meet the fluid requirements of your transmission.
