Service bulletin SSM 51909

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

Mixing MERCON LV and MERCON SP in the same transmission is acceptable. After 30-Jun-2023, MERCON SP ATF will no longer be manufactured and will only be available until inventory depletes.
