Official 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.
Vehicles covered
What a TSB means. Technical service bulletins are repair guidance manufacturers send to dealers — they are not recalls, and repairs are not automatically free (warranty extensions are an exception worth checking). The full document is available via NHTSA’s vehicle lookup.
