1988 Gmc Sierra problems
The Chevrolet Silverado is a range of trucks manufactured by General Motors under the Chevrolet brand. Introduced for the 1999 model year, the Silverado is the successor to the long-running Chevrolet C/K model line. Taking its name from the top trim level from the Chevrolet C/K series, the Silverado is offered as a series of full-size pickup trucks, chassis cab trucks, and medium-duty trucks. The fourth generation of the model line was introduced for the 2019 model year.
The Chevrolet Silverado shares mechanical commonality with the identically related GMC Sierra; GMC ended the use of the C/K nomenclature a model generation prior to Chevrolet. In Mexico, high-trim level versions of the Silverado use the Chevrolet Cheyenne name (not to be confused with the 2003 concept). Competing against the Ford F-Series, Ram Pickup, Toyota Tundra, and Nissan Titan, the Silverado is among the best-selling vehicles in the United States, having sold over 12 million trucks since its introduction in 1998 as a 1999 model year.
History
The Silverado nameplate made its debut for the 1975 model year, becoming the top trim level on all Chevrolet C/K trucks, slotted above Custom Deluxe, Scottsdale, and Cheyenne. For the 1968 model year (seven years before the Silverado), GMC C/K trucks used variations of the Sierra name (Sierra, Sierra Classic, Sierra Grande, and High Sierra). Even after the C/K series officially ended, GM still uses the CK and the CC in their current model codes, to denote a two-wheel drive (CC), and four-wheel drive (CK).
For the 1988 GMT400 model architecture, Chevrolet retained the C/K model nomenclature, with GMC branding its full-size line as Sierras. While sharing the same body and chassis, the model chronology of the Silverado and Sierra are different, with five generations of the Sierra, while four of the Silverado.
In 2018, at the NTEA Work Truck Show in Indianapolis, Indiana, Chevrolet unveiled the first medium-duty Silverado, expanding the model line to a 4500HD, 5500HD, and 6500HD chassis cab. Largely the successor to the 2003–2009 GMT560 chassis, the medium-duty trucks are exclusive to Chevrolet, with no plans for an equivalent GMC version. Instead, Navistar International (now partnering with GM) would sell the medium-duty trucks as a rebadged counterpart, called the CV. This is in fact a very similar nod to how the Avalanche did not have a GMC Yukon–based equivalent, but instead, Cadillac would take its place as the former's rebadged counterpart, the Escalade EXT.
