Select your category below. We provide assistance in finding compatible 2018 GMC Acadia transmissions and differentials for your model year. We identify the correct OEM component for you.
Why Choose OEM GMC Components?
Using inspected second hand GMC parts means you get an original factory part designed for your vehicle's engine and transmission configuration. This part avoids most aftermarket part fitment issues.
Due to the large differences in part configurations through the years, drivetrains, and trims, we use the vehicle information and VIN to authenticate the exact fitment, like verifying the correct 2015 GMC Terrain engine, before the order is placed.

New Dealership Parts vs. Inspected Used GMC Parts
When considering a GMC major repair, the cost, availability, and vehicle compatibility of both new and used components need to be analyzed:
New Dealership OEM Parts
Pros:
- Guaranteed to be zero mileage and fresh from the factory with General Motors
- Includes the standard retail dealership warranty
- Built to the latest design revisions from the factory
Cons:
- ✕More expensive up front for complete engine and transmission purchases
- ✕More frequent manufacturer backorders on older or discontinued model years
- ✕A greater negative impact on the environment from building new materials
Inspected Used OEM GMC Parts
Pros:
- Make a savings of up to 70 percent compared to buying at dealership retail for major powertrain units.
- Original factory-installed fitment with quality GM engineering — no aftermarket parts
- Available for most vintage and difficult-to-acquire GMC vehicle generations
- Divert OEM assemblies from ending up in the landfill by safely repurposing them for a new product.
Cons:
- ✕Shorter warranty periods than brand-new dealership crate components
- ✕Product interchangeability varies by model year and is confirmed through VIN verification before ordering
