GMC is a subsidiary brand of General Motors (GM) that was originally founded in 1912. They primarily focus on trucks and commercial vehicles, but are also responsible for manufacturing buses, pickups, sport utility vehicles and military vehicles. The brand is headquartered in Detroit and sells its automobiles worldwide. The first GMC truck was launched in 1912 at the New York International Auto Show. Since then, GMC has produced a roster of popular models, including the Acadia, C2500 and K3500. GMC and Chevrolet trucks bare many similarities in their overall build and look, although the former is traditionally targeted at professionals. GMC also equipped some of their smaller trucks with V8 engines from Pontiac, Buick and Oldsmobile between 1955 and 1959. We have a range of GMC repair manuals available that are ideal for anyone who wants to perform their own engine servicing and upgrades, or full-body repairs.
