What Customers Say

4.8

Rated 4.8 out of 5 by verified buyers · DIY owners and professional shops across all 50 states

My local shop quoted a reman at almost $7,000. All Auto Parts found a 68k-mile engine with a 90-day warranty and had it at the shop in five days. Mileage matched the paperwork exactly.

Marcus T.Fort Worth, TX · 2014 Ford F-150 · 5.0L Engine

Verified Buyer

Honestly expected a runaround because I found them through an ad. Instead a real person called me back in about two hours, explained the warranty, and I paid nothing until they had the unit located.

Denise R.Tulsa, OK · 2011 Honda Odyssey · Transmission

Verified Buyer

We source three or four drivetrain units a month through All Auto Parts. The VIN matching saves my techs from ordering the wrong variant, and the flat shipping makes quoting customers simple.

Asked a lot of questions about the AFM lifters and they knew exactly what I meant. Got a lower-mileage unit than I expected for the price. Running strong 8 months later.

Kevin M.Albuquerque, NM · 2016 Chevy Silverado · 5.3L Engine

Dealer wanted more than the car was worth. The used CVT they sourced came with mileage documentation and a warranty, and it saved me from having to sell the car.

Ordered on a Tuesday, arrived Friday. It was clean, tagged, and the fitment was correct the first time. Would use them again without hesitation.

Straight Answers

Common Concerns, Answered Honestly

Most people buying a used drivetrain part for the first time have the same worries. Here is how we address each one — no sales spin.

“Isn’t a used part risky?”

Every unit comes from a low-mileage donor vehicle, is inspected before it ships, and carries a written 30–180 day warranty. A used OEM part is built by the original manufacturer to factory spec — unlike a bargain aftermarket copy.

“How do I know the mileage is real?”

Mileage is odometer-verified and documented from the donor vehicle. The exact figure is included in your written quote so you can compare units and make a decision with real information.

“Why not just buy remanufactured?”

Reman units cost 2–3× more and often carry core charges and long lead times. For most daily drivers, a tested low-mileage OEM unit delivers the same reliability at 40–70% less.

“What if it doesn’t fit my vehicle?”

We match by VIN or engine / transmission code, not just year and model. Fitment is confirmed with the yard before dispatch, and covered fitment problems are handled under the warranty.

“I found you through an ad — why trust you?”

All Auto Parts is a registered Texas company with a physical office at 508 S Elm St Ste 104, Denton, TX 76201. You can call (888) 818-5001 and speak with the same specialist throughout your order. No payment is collected until your part is located.

“Will the price change once I call?”

No. Your quote lists the unit price, warranty, and $240 flat shipping as a single delivered total. If you decide not to move forward, there is no charge and no obligation.

“I can find it cheaper on a marketplace.”

Possibly — but usually from an unknown seller with no testing, no mileage proof, and no warranty. We only source from vetted yards so the unit you receive is the unit you were quoted.

“Who actually honors the warranty?”

We do. Your warranty is issued with your order and All Auto Parts coordinates any claim with the supplying yard — you never have to chase down a salvage yard yourself.

Common Questions

Frequently Asked Questions

How does All Auto Parts work?

You tell us the part and vehicle. We search 2,000+ verified salvage yards, confirm mileage and fitment, and send a written quote with the warranty and $240 delivered shipping. If you approve, the part ships direct to you or your shop.

How fast will I hear back?

Quotes go out within 24 hours, and during business hours (Mon–Fri 8am–6pm CT) most customers hear from a specialist in under two hours. Choose “ASAP” in the form if you need a call right away.

Is a quote really free with no obligation?

Yes. There is no fee to request a quote and no payment is collected until you approve a specific unit.

Where is All Auto Parts located?

All Auto Parts is a registered Texas company at 508 S Elm St Ste 104, Denton, TX 76201. We ship nationwide to all 50 states.

What does “used OEM” mean?

It is the original part built by the vehicle manufacturer, pulled from a donor vehicle — not an aftermarket reproduction. You get factory specification and fitment at a fraction of new pricing.

Do you sell parts other than engines and transmissions?

Our focus is drivetrain: complete engines, long and short blocks, cylinder heads, automatic / manual / CVT transmissions, transfer cases, differentials, and torque converters.

How much does shipping cost and how long does it take?

Shipping is a $240 flat rate to any residential or commercial address in the 50 states. Most units arrive in 3–7 business days after payment; same-day dispatch is available from many yards. Freight to a shop with a forklift or dock is the fastest option.

Do I pay before you find the part?

No. We locate the unit, confirm mileage and warranty, and send a written quote first. Payment is only collected once you approve the exact unit.

What payment methods do you accept?

Major credit and debit cards and bank transfer. Card payments are processed through a secure, PCI-compliant processor — we never store your card details.

What does the warranty actually cover?

The warranty covers internal failure of the unit for the stated period (30–180 days depending on the unit). It does not cover installation labor, fluids, gaskets, or damage from improper installation, overheating, or lack of fluid. Full terms are in your quote.

Can you ship to my mechanic instead of my house?

Yes — most customers do. Give us the shop address and we will coordinate delivery to a commercial address with a dock or forklift, which is faster and cheaper to unload.

Is there a core charge?

Typically no core charge on used OEM units. If a specific supplier requires one, it will be clearly listed on your quote before you decide.

What information do you need to quote accurately?

Year, make, model, and part type get us started. Adding your 17-digit VIN, engine size, or transmission code in the notes lets us confirm exact fitment on the first try.

Do you sell to repair shops and dealers?

Yes. Independent shops, dealers, and fleet managers use us as a sourcing desk. Ask about repeat-buyer pricing when you call.
