Tested, warranted used engines for domestic, import, and luxury vehicles — 49 makes covering model years 1990–2021, from 4-cylinder commuters to V8 trucks and performance engines. Every engine is inspected and tested before it's offered for sale.

Every engine passes a compression test on every cylinder, a leak-down test, oil pressure and oil condition inspection, and heat-tab verification to confirm it was never overheated. Mileage is documented from the donor vehicle and every unit is logged to a numbered work order. Fail one check, and it never reaches your quote.

The complete long-block assembly — block, crankshaft, pistons, cylinder heads, valvetrain, timing assembly, oil pan, and valve covers. Courtesy items like manifolds, injectors, and sensors ship free when attached (not warrantied). You also get the pre-installation checklist and access to our specialists throughout your install. Accessories like the alternator, starter, and A/C compressor stay on your old engine.

It varies by unit — we prioritize low-mileage donors and document the actual odometer reading on every quote, so you compare real numbers, not estimates. You'll typically get 3–5 options at different mileage and price points.

With proper installation and maintenance, a tested low-mileage used engine routinely delivers many years and tens of thousands of miles of service — it's the same OEM engine your vehicle was built with. Fresh fluids, a new water pump, and following the pre-installation checklist are what protect that lifespan.

Keep it gentle for the first few hundred miles: fresh oil and filter at install, verify coolant fill and bleed air pockets, avoid sustained high RPM, and re-check fluid levels and torque after the first drives. Then change the oil again early — cheap insurance for a long life.

Plan on new gaskets, seals, timing components, spark plugs, filters, and fluids — and a new water pump is required on engine installs to keep your warranty valid (keep the receipt). Never reuse old fluids.

Yes — automatics, manuals, CVTs, and overdrive units across a wide range of vehicles. Automatics ship with their matched torque converter; manuals are verified for input shaft and case condition. Send your VIN and we'll confirm the exact transmission code your vehicle needs.

Each transmission is verified for shift pressure in every gear, solenoid and valve-body operation, torque converter function (automatics), clutch operation (manuals), and fluid health — checking for burning, metal flake, and contamination. Units with overheat discoloration are rejected.

The complete case with all internals — gear sets, clutch packs, valve body, pump assembly, and oil pan. Automatics include the matched torque converter; sensors attached to the case ship free as courtesy items. Shift linkage, external coolers, and the transfer case (4x4) are not included.

Yes — always. Debris from your failed transmission sits in the cooler and lines, and it will destroy a replacement unit. Flush them thoroughly, install a new filter and fresh fluid of the correct type. Skipping this is one of the most common causes of avoidable failures.

Many late-model vehicles need a TCM relearn or reflash after a transmission swap so shift points adapt correctly. Your installer can handle it with a capable scan tool — ask us about your specific vehicle and we'll tell you what to expect.

Send us your 17-character VIN — it's how we guarantee fitment. We cross-check it against OEM specs to confirm the exact engine or transmission code, including compatible interchanges. Year/make/model alone often isn't precise enough; one model year can have three different engine variants. If a verified part somehow doesn't fit, we replace it free or refund in full.

Your VIN is on the driver's-side dashboard (visible through the windshield), the driver's door jamb sticker, your insurance card, or your registration. Can't find it? Call or text us and a specialist will walk you through it in a minute.

Not every unit we can get is listed online — many sell before we post them. With 39,597 parts in live inventory and a 150+ verified supplier network, odds are we can source it. Text or call with your VIN and we'll send real options, usually within hours.

Yes — always. After your order, we dismantle, inspect, and photograph your exact engine or transmission, then send the photos for your approval. No approval from you, no shipment. If you don't like what you see, you get a 100% refund — no questions asked.

Yes — free freight to all 50 states, included in your quote. No fees added at checkout, no surprises at the loading dock. Most orders are inspected, photographed, and shipped within 3–5 business days of your approval; freight transit adds 2–5 more, so expect 7–10 business days in total. You get door-to-door tracking from the moment it leaves.

Every unit ships on a custom pallet — strapped, wrapped, and fully insured — with freight carriers experienced in automotive components. Damage in transit is rare, and when it happens we work directly with the carrier so you never fight an insurance claim alone.

Both. Shops with a forklift or dock are easiest, but residential delivery with free liftgate service is available at no extra charge — just tell your specialist at quote so it's arranged up front. Someone needs to be present to receive and inspect the freight.

Yes — a tracking number is sent the day your order ships, with door-to-door visibility. Your specialist also keeps you updated at each stage: sourcing, testing, photo approval, and dispatch.

Inspect the unit before signing the delivery receipt. If you see any damage, note it on the driver's paperwork and photograph it — that documentation makes any claim instant. Then report it to us within your 7-day return window and we handle the rest.

Coverage is 3 months on vehicles 1991–2000 and 6 months on vehicles 2001 and newer, included standard at no extra cost. A valid claim gets you a replacement unit of the same specification at no additional charge, with freight covered both ways. Claims are handled directly by our own team — no third-party runaround. Extended coverage is available up to 3 years on every unit — ask your specialist at the time of purchase. Full terms are on our Warranty Policy page.

Internal mechanical defects in materials and workmanship — block, heads, and internal components on engines; gear sets, valve body, and internals on transmissions. Bolt-on accessories, courtesy items, fluids, and labor are not covered. A valid claim gets you a replacement unit of the same specification at no additional charge, and we cover freight in both directions.

At delivery — the day the freight carrier drops your unit. That's also when your 7-day return window and installation window begin, so plan your install promptly.

Install within 30 days of delivery using an ASE-certified mechanic, follow the pre-installation checklist, install a new water pump on engines (keep the receipt), use fresh fluids and a new filter, and keep your installation invoice on file.

The big ones: overheating or low-fluid damage, missing or damaged heat tabs, unauthorized modifications, skipping the new water pump on engine installs, missing installation receipts, and not reporting issues within the stated windows. Read the Warranty Policy page before installation — five minutes that protects your coverage.

Five steps: contact us with your order number, provide a diagnostic report showing the issue originates from our unit, submit your installation invoice, our team reviews the claim, and approved claims get a free replacement with return shipping covered by us.

7 days from delivery. If the part is defective, damaged, or not as described, report it within 7 days with photos and we'll arrange the return — return shipping covered by us, no restocking fee. You choose a replacement unit of the same specification or a full refund.

Photograph the issue and contact us within your 7-day return window. Approved returns ship back free — we cover return freight. You'll get a replacement first; if we can't resolve it, you get your money back.

Yes — cancellations within 24 hours are free. After 24 hours a 20% restocking fee applies, and if the order has already shipped, round-trip freight is added. That's why we confirm everything with you — photos included — before the truck loads.

Two layers of protection: at the photo-approval stage, if you don't like what you see, you get a 100% refund before anything ships. After delivery, you're covered by a 7-day money-back guarantee — free return shipping and no restocking fee on defective, damaged, or not-as-described parts.

Three ways: use the year/make/model search on our homepage to order online, text your VIN to (859) 800-5484 for matched options with prices, or call and a specialist will handle everything personally. Either way, your unit isn't shipped until you've approved real photos of it.

Engines start around $700 and transmissions around $650, ranging up to $23,000 for late-model and performance units. Your exact price depends on year, make, model, and mileage — text us your VIN and we'll send real options with prices in minutes.

Visa, Mastercard, American Express, Discover, Diners Club, PayPal, Apple Pay, Google Pay, and Shop Pay — all through Shopify's SSL-encrypted secure checkout. The price your specialist quotes is the price you pay.

We accept all major cards and digital wallets through secure checkout. If you need payment flexibility, ask your specialist when you get your quote — installment options may be available on eligible orders.

No hidden fees. Free shipping is built into the quote, there's no core charge, and you keep your old unit. What you're quoted is what you're charged — nothing extra appears at checkout or on delivery.

We supply the part; installation is by an ASE-certified mechanic or shop — that's a warranty requirement, so keep their invoice. We support the install with detailed guidelines, the pre-installation checklist, and our specialist team on call throughout. Keep the installation invoice — it's required for warranty claims.

Tell us your location when you order and we'll help point you toward qualified installation professionals in your area. Installation by an ASE-certified shop is required to keep your warranty valid — their invoice is your proof of professional installation.

Our specialists support you through the whole project: pre-installation consultation, checklist walkthrough, troubleshooting during the install, and post-installation guidance. Call or text any time — a real parts specialist answers, not a script.

A used unit is OEM — pulled from a low-mileage donor vehicle, inspected and tested, with factory tolerances intact. A remanufactured unit has been disassembled and rebuilt with replaced components. For most repairs, a tested low-mileage used unit is the better value — but if reman is the right call for your vehicle, we'll tell you honestly.
