The website offers light- and medium-duty Body Builder Manuals, Technical Bulletins on issues that have come up during the model year, Best Practice Manuals with engineering recommendations and guidelines for special vehicle manufacturers; links to other fleet or commercial vehicle-related GM and non-GM websites, a variety of FAQs covering common upfitter questions, and a generic (non-VIN specific) Incomplete Vehicle Documents database that is searchable by model year.

Once a case is received, it will be reviewed and additional information about the vehicle and the scope of the upfit may be requested. You will receive a telephone call and/or e-mail from a technical liaison engineers within 48 business hours of receipt of the request. The technical assistance is intended to be an advisory service for commercial vehicles only.

 

Upfitter Bulletins

Under the Technical Bulletin tab, bulletins covering light-duty, medium-duty, and passenger vehicles are provided in a PDF format. Topics cover mid-year vehicle design changes, GM information that affects upfitter modifications, and frequent issues that upfitters encounter.

The bulletins can be searched by model year, vehicle and vehicle type, or select “Show all bulletins” to view all bulletins currently available. (Fig. 13)
