The Chevy C3500 is one of the heavy-duty trucks in the Chevrolet line of full-size trucks. It is a two-wheel drive vehicle that is a full ton in size. The newer generations of this vehicle offer independent front and back suspension, and even though it is a large truck, it still runs on unleaded fuel instead of diesel fuel like some other larger trucks. Diesel fuel options were also available in the C3500, and in 1991, the 4L80-E automatic transmission became available for this truck.
