## NHTSA's summary

Customer Satisfaction. Certain vehicles, equipped with the 10\-speed automatic transmission \(RPO MF6\), may have a condition in which the transmission manual shaft pin was not seated properly. If the shaft pin were to migrate out of position, the driver may find they cannot shift the vehicle into any gear other than the last one selected. The customer may be unable to return the vehicle back to park, in which case they would be required to engage the parking brake to ensure the vehicle does not roll from its intended position. Dealers will replace the transmission manual shaft pin. Private Message sent to select dealers.
