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. All new trucks purchased from TLG are enrolled automatically with Guru and is free to all new truck customers for life, as long as the truck is owned by the original buyer.
