If You Need It, We Have It. Ship It Fast, Back It Right.
Don’t let a broken engine or failing transmission keep your vehicle off the road. Advanced AutoPlex has quality-tested used engines and remanufactured transmissions ready to ship to any address in the United States — with warranty documentation included on every order.
Used Engines & Transmissions for Every Make and Model in America
Finding a reliable used engine or transmission in the USA used to mean calling salvage yards, driving across town, and hoping the part you picked up actually worked. Advanced AutoPlex was built to change that. We give American drivers, independent mechanics, and auto repair shops direct access to a verified inventory of used engines, remanufactured transmissions, transfer cases, and OEM auto parts — all inspected, documented, and ready to ship nationwide with free freight delivery.
Every engine in our inventory goes through a hands-on inspection process before it’s listed. We document compression test results, verify mileage against the donor vehicle’s records, and photograph each unit so you know exactly what you’re getting before you order. Our remanufactured transmissions are fully rebuilt to factory specifications using new OEM-grade components, then dyno-tested for performance before packaging. Whether you’re replacing a 5.3L in a Chevy Silverado, a CVT in a Honda CR-V, or a 5.7L HEMI in a Dodge Ram — we have the part, the documentation, and the warranty to back it up.
We ship to all 50 states. Most orders leave our facility within one to two business days via insured LTL freight, delivered directly to your mechanic’s shop or your home address. Our support team confirms fitment with you before your order is processed — because the wrong part shipped fast is still the wrong part. At Advanced AutoPlex, we do it right the first time, or we make it right. That’s not a slogan. That’s our policy.
F.A.Q.
Have any Question?
Do your used engines come with a warranty?
Yes. Every used engine and remanufactured transmission sold by Advanced AutoPlex includes a written warranty. Coverage terms vary by part and condition grade, but all major components are protected. We provide warranty documentation with every order so you have it in writing before installation begins.
How do I know the mileage on a used engine is accurate?
We document mileage from the donor vehicle’s title and odometer records before any engine enters our inventory. Compression test results are also recorded for every engine. We share this documentation with you before you commit to a purchase — no guessing, no vague descriptions like “low miles.”
Can I send the part directly to my mechanic’s shop?
Absolutely. Just provide your mechanic’s shop name and address at checkout and we’ll ship directly to them. We do this regularly for independent repair shops across the country. Your mechanic will receive the part on a pallet or crate, ready for installation.
Do you ship to my state?
Yes — we ship to all 50 US states via insured LTL freight. Most engines and transmissions are delivered within 3 to 7 business days depending on your location. Shipping is free on all orders. You’ll receive a tracking number within 24 to 48 hours of your order shipping.
How do I know the part will fit my vehicle?
Before your order ships, our team confirms fitment using your vehicle’s year, make, model, engine displacement, and engine code. We cross-reference this against the part’s donor vehicle specifications. If there’s any fitment question, we contact you before processing — not after.
What is the difference between a used and a remanufactured transmission?
A used transmission is pulled from a salvage vehicle, inspected, and sold in its current working condition — typically 30 to 60 percent cheaper than a remanufactured unit. A remanufactured transmission is fully disassembled, worn components replaced with new OEM parts, reassembled, and dyno-tested to factory specifications. Both come with a warranty. We help you choose the right option based on your vehicle, budget, and how long you plan to keep the car.
