Manufacturer summary

Original wording in English

Service Update. On a small number of the vehicles identified above, the electrical connector to the transmission valve body solenoids may not be fully seated. 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.

Repeated filings are grouped only when make, bulletin number, publication date and complete summary agree. Original record numbers are retained. Older publications remain available, and an explicit later version is shown when established. Pre-1994 vehicle associations are separated from default results; an unspecified year does not mean all model years apply.
