June Service Newsletter from the Experts at GM TAC

The latest diagnostic assistance from the professionals at the GM Technical Assistance Center is now available in the June GM Technical Assistance Center (TAC) Newsletter. It covers a number of concerns that TAC is addressing every day on cases with dealerships. Each month, we publish the newsletter as a PDF, making it easy to view online or print for reference.

With the tips provided by TAC, dealerships get additional information on the latest diagnostics and repairs to help get vehicles back to customers quickly. Each newsletter provides details about recent Bulletins and Preliminary Information (PI) that have been released along with tips on other known concerns, diagnostic testing, parts information and availability, and new product news.

The newsletter is organized in categories covering General; Engine; Electrical, Chassis and Trim; Transmission and Drivetrain; Infotainment and OnStar; Hybrid and EV; and DCM and TAC Cases.
