Who we are
A powertrain specialist — not a parts marketplace.
American Motor Supply sells one thing: quality used powertrain. Engines, transmissions and transfer cases for domestic and import vehicles, sourced from our own inventory and a nationwide network of vetted partner yards.
That focus is the point. Because we aren't juggling body panels and brake pads, our specialists know interchange numbers, engine codes and sub-model variants cold — the details that decide whether a used assembly bolts straight in or costs you a second weekend on the lift.
Everything else follows from it: VIN verification before we quote, bench testing before a unit is cleared, photographs before it's crated, free freight to all 50 states, and a warranty that's published in full on this site rather than produced when you claim.
If we wouldn't put it in our own truck, it doesn't go on your pallet.— the standard every unit is inspected against
Why buyers choose us
Six reasons people trust us with an engine-sized decision.
Every one of these is either shown to you before you pay or written into a policy on this site. None of it is a slogan.
Fitment verified against your VIN
A used assembly can come from a different year or model and still be correct — as long as the interchange is right. We check that first, and if a verified part still doesn't fit, we replace it or refund you in full.
Tested by technicians, not sorted by price
Compression and leak-down testing on engines; pressure, shift quality and case inspection on transmissions. Anything that fails is rejected — never discounted and passed to the next customer.
Nothing ships until you say yes
You receive photographs of your actual unit — casting numbers, ID tags, mileage sticker, the crate it travels in. Decline and you get every dollar back, with no restocking fee and no freight charge.
Free freight, quoted honestly
Shipping to all 50 states is inside the price you're quoted. Anything that isn't included — a residential liftgate, a redelivery — is named before you pay rather than invoiced afterwards.
Warranty published before you buy
180 days of parts coverage from delivery as standard, with extended terms available at quote. What's covered and what voids it is on the warranty pages — not hidden until a claim lands.
One specialist owns your order
The person who quotes your part chases the yard, sends your photos and answers the phone when the truck is late. No queue, no ticket number, and your number is never sold to other yards.
How it works
From your VIN to your workshop in four steps.
Same process on every order, whether it's one engine for a family car or six transmissions for a fleet.
Send the VIN
Call, text or email your VIN with the engine or transmission code. We verify fitment before quoting a price.
We source and test
Pulled from our own stock or a vetted partner yard, then bench-tested and inspected before it's cleared.
You approve the photos
Your actual unit, photographed from every angle that matters. Approve or decline — the choice is yours.
Crated, shipped, covered
Palletised and insured, freight included, warranty running from delivery. Most orders ship in 3–5 business days.
Operational facts, not marketing lines
Built into every order.
- Fitment checked against your VIN before you're quoted a price.
- Every unit tested before it's cleared for sale — no untested cores.
- Real photos of your unit sent for approval before dispatch.
- Free insured freight to all 50 states, included in the quote.
- 180-day warranty from delivery, extended terms up to 3 years.
- 30 days to inspect and return — the full terms are published here.
Our biggest difference
You see the engine before you own it.
Most used-part sellers ask you to pay first and hope second. We do it the other way round: once your order is placed, your unit is photographed on the floor and that set comes straight to you.
Casting numbers, identification tags, mileage sticker, and the pallet it will travel on. If anything looks wrong, you decline — the order is cancelled and refunded in full, no restocking fee and no freight charge. It costs you nothing to be sure.
✓ Approve — it ships free
✕ Decline — full refund

Backed in writing
Coverage that starts the day it reaches you.
Standard coverage is included on every unit at no extra cost. Extended terms are quoted up front, never sold to you after a failure.
Standard
180 days
Parts coverage from the date of delivery on every engine and transmission we ship. Nothing to buy, nothing to register.
Extended
1 year
A longer runway for daily drivers and work vehicles, quoted at the time of purchase rather than added later.
Extended
3 years
Our longest term, for buyers who want the unit covered well past the installation and the first hard season.
Who we supply
Same part. Four very different conversations.
Vehicle owners
One car, one shot
You're doing this once and it has to be right. We walk you through fitment, mileage and exactly what your installer will need.
Repair shops
Bay time is money
Firm lead times, photos you can forward to your customer, and a specialist who calls back before the car ties up your lift.
Dealerships
Paperwork that lands
Interchange detail, donor information and invoices your service department can file, on units that won't come back next month.
Fleets
Repeat, not one-off
Recurring makes and models, multiple units at a time, and pricing built for volume rather than a single sale.
What we stock
Two catalogues. Both tested before listing.
Compression-tested used engines
Low-mileage, VIN-matched engines for cars, trucks and SUVs — compression and leak-down tested, mileage recorded, and photographed before they ship. Long blocks and complete assemblies for domestic and import makes.
Browse used engines →Shift-tested used transmissions
Automatic and manual transmissions tested for shift pressure, solenoid operation and case condition, then matched to your VIN so they bolt up first time. Transfer cases available on request.

Send the VIN. Get a straight answer.
You'll get real options with recorded mileage and a real price, usually the same day. Nobody here works on a commission that depends on you buying today.
