What is the power train warranty on a 2007 Chevy Silverado?

The powertrain warranty on a 2007 Chevy Silverado is 5 years/100,000 miles, whichever comes first. This is the standard General Motors powertrain warranty for that model year. However, it's crucial to check the specific details in the original warranty booklet that came with the truck, as there might have been variations depending on the specific trim level or any extended warranty purchased.
