# Service bulletin SF659

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.

On certain vehicles, the maximum driving distance parameter that prompts notification to change the transmission oil is set incorrectly. The parameter is set to provide an indicator no later than 965,400 km \(approx. 600,000 mi\), when it should have been set to provide an indicator no later than 300,000 km \(approx.186,000 mi\).
