Buy Quality Used GMC Parts at Premium Used Auto Parts

When you need a major part replaced on your GMC, you don't need to pay dealership prices or risk aftermarket parts not fitting right. At our facility, we have used GMC components that are built by GM to fit your truck or SUV's engine and transmission configuration.

GMC changes part configurations for different model years, drivetrains, and trims. The 2015 GMC Terrain, for example, could have a 2.4L or a 3.6L engine. Because of these variations, we have to confirm your vehicle's configuration by checking your VIN to pick the correct parts for you.

Used GMC Parts by Model: Trucks, SUVs & Vans

PUAP provides many of the powertrain and drivetrain components for various models in GMC's current and old lineups. Since there is some engine and transmission interchangeability between models like the Silverado/Sierra and the Yukon/Tahoe, we have an even larger pool of potential donor parts.

Used GMC Engines and Transmissions by Model and Year

Each generation of GMC truck and SUV models uses different engines and transmissions. Sometimes models released in the same year use different engine and transmission combinations. Because the eighth character in the VIN identifies the engine, it is the easiest way to determine which engine a vehicle has.

New Dealership Parts vs. Inspected Used GMC Parts

Before a major GMC repair, compare new dealership parts and inspected used OEM parts on cost, availability, and fit:

New Dealership OEM Parts

Pros:

  • Zero miles, direct from General Motors
  • Standard dealership warranty
  • Latest factory design revisions

Cons:

  • Higher upfront cost for complete engines and transmissions
  • More frequent backorders for older or discontinued models
  • Higher environmental impact from new manufacturing

Inspected Used OEM GMC Parts

Pros:

  • Up to 70% savings compared with dealership retail on major powertrain units
  • Original GM factory parts, not aftermarket
  • Available for many older and hard-to-find GMC generations
  • Keeps working OEM assemblies out of landfills

Cons:

  • Shorter warranty than new dealership crate components
  • Interchangeability varies by model year and is confirmed by VIN before ordering

Buying GMC parts used to be complicated. With your VIN, we can verify your factory part numbers and ensure a part will fit. Whether you are after a 5.3 Liter engine, or a 6 speed transmission, we can help and carry many GMC OEM parts.

Repair or Replace Your GMC? Compare Before You Shop

When something goes wrong with the engine or transmission, a lot of owners start looking at the price of the 2026 GMC Sierra 1500, looking at GMC Sierra 1500 and Yukon listings, and finding GMC dealers to check out their lease offers. Before taking on a new payment, think about how much it would cost to repair your current truck.

Oftentimes you can purchase a used GMC engine or transmission for less than it would cost to buy a new to you vehicle and used GMCs for sale have an uncertain history. It is good to know what the real cost is to replace the GMC engine.

How We Inspect and Verify Used GMC Parts

Each GMC transmission, engine, and drivetrain is inspected during shipping preparation.

Donor Vehicle Selection

We focus on trucks and SUVs that have been in an accident, rather than mechanical condition, when determining which donor vehicles to purchase. We review each vehicle's history.

Mechanical Inspection

Each assembly is inspected for various types of defects before being offered for sale. Defects can occur during the manufacturing process and also during subsequent processes such as coating, plating, and cleaning.

GM Part Number Verification

We use genuine OEM parts from GM, so the part numbers and casting marks on your parts match what GM uses. This means you are not getting aftermarket parts.

VIN Fitment Check

Prior to shipping your order, we verify your VIN to engine, transmission and drivetrain configurations.

Additional Used GMC Parts: Drivetrain, Suspension & Electronics

In addition to engine and transmission components, we have used OEM transfer cases and axle assemblies for 4WD GMC Sierra and Yukon models. We also have used OEM struts, shifter assemblies, instrument clusters and climate control modules. Electronic modules can vary by year and model. Some modules require programming to your vehicle. A quote can be given with your VIN.

Signs Your GMC Needs a Replacement Engine, Transmission, or Transfer Case

Engine Warning Signs

A combination of different symptoms may indicate failure of the internal components of the engine. Some 5.3L and 6.2L V8 engines, for example, the ones used in the Sierra and Yukon, have failed due to lifter failure as part of the cylinder deactivation function. If not corrected, this can cause the camshaft to fail as well.

Transmission Warning Signs

Signs of a bad torque converter include shudder at 100% throttle, harsh up-shifting, and delay or slippage when up-shifting. The 2015 to 2019 Sierras and Yukons with the 8L90 transmission are subject to converter shudder. An engine overhaul including a transmission rebuild will cost around the same as a used OEM transmission, so the transmission is replaced instead.

Transfer Case Warning Signs

The presence of grinding or clunking sounds or the message “Service 4WD” is typically attributed to problems with the transfer case or encoders on 4WD Sierra and Yukon models (primarily the towing and off-road models).

Have a mechanic confirm the diagnosis, then use the part finder to check availability.

Yes. We have used OEM parts for sale for GMC Sierras, Savanas, Canyons, Terrains, Acadias, Yukons, and vans. We also have used OEM parts for GMC and Chevrolet SUVs.

Send us your vehicle identification number (VIN). It’s 17 digits long. Our team searches for your vehicle’s engine code (i.e. 5.3L or 6.2L V8). We also verify available GM parts. Part numbers are assigned to each engine. We process your engine shipment after verification.

Yes. Used OEM GMC engines, transmissions and major assemblies are inspected by us and include our standard 90-day parts and labor warranty.

Use your GMC's year, model and VIN to use the part finder for transmission parts. For your part, or to place an order, call 1-800-606-1107. GMC trucks have several transmissions, a few being the 6L80, 8L90, and 10L80, determined by the year and engine. Your VIN will confirm which transmission is in question.

Often, yes. GMC and Chevrolet share powertrains across Sierra and Silverado, Yukon and Tahoe, Canyon and Colorado, and Savana and Express. A Chevrolet donor part fits your GMC when engine, transmission, and model year match, confirmed by VIN before shipping.

Yes. Heavy-duty Sierra 2500HD and 3500HD parts are available, including 6.6L Duramax diesel and gas V8 engines and transmissions. Because these vary by model year, enter your VIN in the part finder to confirm availability and fitment.

Your 17-digit VIN is on the lower driver's-side corner of the windshield and on the driver's door jamb sticker. It's also printed on your registration and insurance card. Include it with your quote request so fitment can be confirmed.

A core charge is a refundable deposit included with some engine and transmission orders. It's refunded once your old unit is returned in rebuildable condition. Terms vary by part, so ask for the details on yours.

Yes. Used GMC engines, transmissions, and drivetrain parts ship nationwide, so you can order from anywhere in the U.S. and have your part delivered directly to you.

Availability is limited, since few 2025 and 2026 GMC Sierra 1500 trucks have entered the donor supply.

Send us your VIN and we'll confirm the right fit before you order, whether you need a GMC engine, transmission, or drivetrain component.
