FOCUS ON THE ASSEMBLY YOU NEED
A replacement starts with the right details.

Looking for used GMC engines? Have your VIN, model year and engine RPO code ready. Many GMC trucks share engine families with Chevrolet, so the code matters more than the badge.

A GMC transmission has to match the transmission RPO code and drivetrain. Ask what is included with the unit you are considering.

GMC prints three-character RPO codes on the Service Parts Identification label, usually in the glovebox. They identify the factory engine and transmission, so send a photo with your VIN.
Used engines and transmissions are previously operated replacement components. We combine owned stock with supplier sourcing, so confirm the exact specification, availability, price and delivery terms before ordering.

ANSWERS BEFORE YOU ORDER
Start with your GMC model, year and VIN. For an engine, confirm the displacement and engine code; for a transmission, confirm the transmission code and drivetrain. The model name alone does not confirm compatibility.
Price depends on the exact assembly, its condition, documented mileage where available and current stock. Call with your vehicle details for a quote, and confirm the delivered price and any core charge before you order.
We source used engines and transmissions for GMC models such as the Sierra 1500, Sierra 2500HD, Canyon, Yukon, and others. Choose your model to start a request; availability is confirmed for your specific vehicle.
ADS Auto Part serves customers across the United States. Give us your ZIP code and confirm shipping eligibility, freight access and timing for your address before purchase. Do not assume local pickup is available.
Warranty options up to three years are offered. Confirm the written terms for your part: coverage period, covered components, exclusions, installation requirements and the return process.
