Option Cost Reliability Warranty Fitment Match
Used OEM (our inventory) $$$ Best Value High Up to 3 years VIN-matched
New OEM (dealer) $$$$$ 2-4× more High Manufacturer Exact
Aftermarket / Rebuilt $$$$ Varies 6-12 mo May adapt
Junkyard $ Cheapest Unknown None DIY

Tested used OEM hits the sweet spot — same engineering as new, fraction of the cost.

Frequently Asked Questions

What is the warranty?
Up to 3 years, depending on the specific unit. The exact warranty term is listed on each product page.
What does ASE-tested mean?
ASE-certified technicians compression-test every cylinder and run leak-down evaluation on engines. Transmissions are Shift-Tested through all gears under load. Plus noise & smoke verification, visual inspection, and multi-angle photography before shipment.
How long until delivery?
Prep and ship time is 3-5 business days. Transit time is 2-3 business days after dispatch via freight carrier. Total: typically 5-8 business days from order to delivery.
Can I see photos before I buy?
Yes. Multi-angle photos of the actual unit sent before payment. If you do not approve the photos, you get every dollar back — no questions, no restocking fees, no return freight charges.
Do I need my VIN?
Strongly recommended for exact-fit matching. Engines and transmissions vary significantly by trim, body style, drivetrain (FWD/AWD/RWD), and year. Text your VIN to +1-307-441-5554 and we'll match options in minutes.
What if I do not approve the photos?
Every dollar back. No restocking fees, no return freight charges. Pay first, see your exact unit, ship third — full refund if you do not approve.
Why cheaper than dealer new?
Used OEM from low-mileage donor vehicles. Same engineering as factory new, fraction of the cost. Most dealer prices are 2-4× our pricing for identical parts.
When can I reach customer service?
Mon-Sat, 8:30 AM – 10:30 PM Eastern. Call 1-877-313-8995 or email info@autopowersource.com.

Our 6-Step Inspection & Shipping Process

Every engine and transmission we ship has been through these six steps:

1. VIN-Matching
We match the donor VIN to your VIN to confirm engine/transmission code, emissions calibration, and drivetrain fit.
2. Tested & Verified
ASE-certified technicians compression-test every cylinder and run leak-down evaluation on engines. Transmissions are Shift-Tested through all gears.
3. Noise & Smoke Verification
Units are run to verify normal mechanical sound and clean operation — catches internal wear static tests miss.
4. Visual Inspection
Every accessible component is inspected: turbos, manifolds, valve covers, accessories, sensor harnesses.
5. Photograph & Catalog
Multi-angle photos sent to you BEFORE we ship for your approval.
6. Palletize & Ship
Strapped on a heavy-duty wooden pallet, shipped via freight at no charge.

Our Photos-Before-Shipment Guarantee

Before any engine or transmission leaves our warehouse, we send you multi-angle photographs. You approve. If you do not approve, you get every dollar back — no questions, no restocking fees, no return freight charges. On top of 30-day money-back and up to 3-year warranty.
