  • Your Go-To Commercial Fleet Service Liaison

    Guru is your 24-hour dedicated service expert for over-the-road fleet maintenance to ensure the success of your repair. Guru monitors repairs and responds to each customer's individual needs. As a liaison between commercial fleet managers and dealerships, Guru shares timely updates between fleet owners, managers, and repair facilities, and will work with you to diagnose priority and immediacy of repairs. Guru is also available to answer questions ranging from electrical troubleshooting to after-treatment systems, empowering fleet managers to make informed decisions about equipment and fleet service needed. Finally, through its advanced SmartLinq technology system, Guru can help fleet managers monitor each truck and diagnose an issue before it even gets into a service bay.

    Purchasing and Pricing

    All pre-owned trucks purchased at TLG are automatically enrolled in a 90-day free trial of Guru. A one-time registration fee of $9.95 per truck is required to enroll in the Guru program followed by a $45 fee per call after the 90-day trial expires.

    Service Commitment

    Guru will work with you to create a customized fleet service program to your unique operation.

    Reduced Wait Time on Service

    Reduced Wait Time on Repairs

    Drivers are met with a professional service counter, and technicians maintain direct communication with Guru as repairs are made.
