Caution: Do not use old seal rings. Install NEW seal rings. Reusing old seal rings may cause internal transmission leaks and transmission damage.

Note: Some models have seal rings with installation identification marks that consist of approximately 11 evenly-spaced injection molding gate trim rings and/or a white stripe printed on one side. This installation orientation must be observed to avoid fluid leakage which may cause shift concerns. Models utilizing an inner O-ring seal have accompanying outer seal rings that contain anti-rotation tabs and can only be installed one way.
