Summary

This customer satisfaction program updates the TCM software in affected vehicles to provide improved detection and over warning of electrical circuit failures in the TCM. As communicated in a previous Customer Satisfaction Program (14M02), electrical circuit failures within the TCM may develop and result in intermittent symptoms of loss of transmission engagement while driving, no-start, or a lack of power. Updating the TCM software will help ensure the vehicle operator is alerted to potential issues with the TCM prior to failure.

Owners of these vehicles have filed 5,470 complaints in the transmission category.
