Service bulletin N182193520

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.

DTC P2718 or P2720 may set resulting in the Check Engine indicator illuminating, and the transmission reverting to a ?limp home? mode providing limited forward gear selection. Dealers are to access the transmission valve body solenoids and fully seat the connectors.
