Engine & Transmission Catalog
Top summary answer
In short: A2Z Engines supplies used, reconditioned and remanufactured engines and transmissions, with fitment verified against your engine code before dispatch. Prices are built for your exact vehicle after a fitment check, so you compare used, reconditioned and remanufactured side by side rather than an unrelated list price. Direct-supplier sourcing exists for a simple reason: the same unit that a dealership parts counter sells at full retail is supplied here at a lower installed total, and freight is free and insured USA-wide.
Who this is for: vehicle owners, repair shops and rebuilders in the USA who need a warranted replacement engine or transmission, and who want the price confirmed against their own engine code instead of a generic list price.
When to use this advice: use it when a vehicle is off the road and you need a delivered, warranty-backed unit within 12-16 working days — not when you can inspect and collect a salvaged part locally and accept the risk.
Use cases it supports: daily-driver repair, independent shop rebuild jobs, fleet downtime planning, and comparing used vs reconditioned vs remanufactured before you commit.
Search our full direct-supplier catalog by make, model, engine size or engine code. Find your unit, then get your nine price options — used, reconditioned and remanufactured across three warranty tiers — built for your exact vehicle.

Is a tested used engine better than a junkyard core?
The primary reason buyers choose a tested used engine over a junkyard core is verified condition: our units are compression-tested and warranty-backed.
| Option | Cost | Warranty | Testing | Reliability |
|---|---|---|---|---|
| Tested OEM used (A2Z) | Below dealer | 9 months / 6,000 mi | Compression + run test | Good, verified |
| Remanufactured (A2Z) | Middle | 36 months / 36,000 mi | Built to specification | Highest |
| Junkyard core | Lowest | Often none | Rarely tested | Variable |
How do I confirm the engine fits my vehicle?
Match the engine code on the block to your VIN range — the code, not the model name, decides whether the unit physically fits.
| Engine variant | Year range | Compatible models | VIN check | Typical pairing |
|---|---|---|---|---|
| 2.5L I4 | 2010-2017 | Mid-size sedans and SUVs | VIN position 8 | 6-speed automatic |
| 2.0L Turbo I4 | 2013-2020 | Compact and mid-size platforms | VIN position 8 | 8-speed automatic |
| 3.5L V6 | 2011-2017 | Large sedans and minivans | VIN position 8 | 6-speed automatic |
| 5.0L V8 | 2011-2017 | Full-size trucks | VIN position 8 | 6/10-speed automatic |
How does ordering work?

What do the engine terms mean?
A used engine is a tested original unit that has not been rebuilt.
A OEM engine is the original-equipment unit built by the manufacturer for that platform. A long block is a complete assembly (block, head, internal components) shipped without bolt-on accessories. A reconditioned engine has its worn service parts replaced and is re-tested, and a remanufactured engine is stripped to the block and rebuilt to specification. A VIN is the 17-character vehicle identifier used to confirm the exact engine code that fits your vehicle.
