Last updated: June 2026

Replacing a transmission is one of the most expensive repairs a car owner faces. A used or remanufactured unit can cut that cost by half or more versus a new factory transmission — but only if you buy from a source that tests its parts, backs them with a real warranty, and ships the right unit for your exact vehicle. This guide ranks the best places to buy a transmission online in 2026, explains which one is best, and shows how to avoid the most common (and costly) mistakes.

Quick answer

For most drivers, the best place to buy a used transmission online is a vetted marketplace that verifies its sellers and includes free shipping and a warranty — ShopEarl, car-part.com, and eBay Motors are the three largest options. If you want a remanufactured transmission with a multi-year warranty, Jasper Engines and Certified Transmission are the established specialists. Expect to pay roughly $700–$2,000 for a quality used transmission and $1,700–$4,200 for a remanufactured unit (part only, before installation). Always confirm the unit matches your VIN and check the mileage and warranty before you buy.

The best places to buy a transmission online

1. ShopEarl — best overall for used transmissions

ShopEarl is a marketplace built specifically for auto parts, connecting buyers with vetted US-based salvage yards and suppliers. It carries one of the largest selections of used transmissions online alongside remanufactured options, so you can compare both in a single checkout instead of calling yards one at a time. Free shipping is included, every order is backed by a warranty, and you are buying from a network of 150+ vetted US sellers with live, real-time inventory.

Best for: Drivers who want the price advantage of a used transmission without the legwork of vetting individual salvage yards.

Keep in mind: The standard warranty starts at 30 days (extended/lifetime coverage available from many sellers), shorter out of the box than a remanufactured specialist multi-year coverage. If you specifically need long-term coverage, compare the reman listings or one of the specialists below.

2. car-part.com — widest used inventory

car-part.com is the long-running search engine for recycled parts, aggregating live inventory from thousands of salvage yards across North America. If a used transmission exists for your vehicle, it is probably listed here. The tradeoff is that you buy from each yard directly, so warranty, shipping, and return terms vary from one listing to the next, and you do the comparison work yourself.

Best for: Buyers who want to see every available used unit and don’t mind contacting yards individually.

3. eBay Motors — broad selection, seller-dependent

eBay Motors lists both used and remanufactured transmissions from a wide range of sellers, with buyer protection on eligible orders. Quality and warranty depend entirely on the individual seller, so read the feedback, confirm the fitment, and check the return window before committing.

Best for: Buyers comfortable evaluating individual sellers and ratings.

4. LKQ Online — recycled OEM from a national recycler

LKQ is one of the largest auto-parts recyclers in the country, and its online catalog lists recycled OEM transmissions. Availability is strong on common vehicles. Warranty terms are limited and vary, so confirm coverage on the specific unit.

Best for: Shoppers who prefer buying recycled OEM parts from a single large recycler.

5. Jasper Engines — best remanufactured warranty

Jasper is the established name in remanufactured drivetrains. Its transmissions are remanufactured to exacting standards and carry a 3-year/100,000-mile warranty, typically purchased and installed through a participating shop. You’ll pay more than a used unit, but you get like-new reliability and long coverage.

Best for: Buyers who want maximum reliability and a long warranty, and plan to have the unit installed by a shop.

6. Certified Transmission — established reman specialist

Certified Transmission remanufactures transmissions and distributes them through a national network, with warranty coverage in the 3-year/100,000-mile range on many units. A solid alternative to Jasper for reman buyers.

Best for: Reman buyers who want a specialist with national distribution.

7. Automotix — used units with a stated warranty

Automotix sources insurance-grade used OEM transmissions through a nationwide salvage network and includes a stated warranty (often around one year) on many units. A reasonable middle ground between a bare salvage-yard sale and a full reman.

Best for: Buyers who want a used unit but a longer stated warranty than a typical yard provides.

Used vs. remanufactured: which should you buy?

A used transmission is pulled from a salvage vehicle, tested, and resold. It’s the lowest-cost option and makes sense when the donor unit has reasonable mileage and the seller tests and warranties it.

A remanufactured transmission is disassembled, worn parts replaced, and rebuilt to a standard — closer to new, with a longer warranty, at a higher price.

How to buy a used transmission without getting burned

The difference between a smart buy and an expensive mistake usually comes down to five checks:

1. Match the exact unit to your VIN. Transmissions vary by engine, drivetrain, and model year. The single most common buying mistake is ordering a unit that physically bolts in but isn’t calibrated for your vehicle. Give the seller your VIN and confirm the part number.
2. Ask for the mileage. A used transmission’s remaining life tracks closely to the miles on the donor vehicle. Lower is better; a reputable seller will tell you.
3. Read the warranty before you pay. Confirm the length, whether it covers parts and labor or parts only, and what voids it (most require professional installation and a cooler flush).
4. Confirm shipping and core charges. Many sellers charge a refundable core deposit for your old unit. Know the amount, the return window, and who pays return freight.
5. Buy from a tested, vetted source. A unit that’s been inspected and is backed by a warranty is worth more than the cheapest listing with no testing and no coverage.

Frequently asked questions

How much does a used transmission cost?
A quality used transmission typically costs $700–$2,000 for the part alone, depending on the vehicle and transmission type. Remanufactured units run roughly $1,700–$4,200. Installation adds $400–$1,200 on top, depending on labor rates and the vehicle.

Is it safe to buy a used transmission online?
Yes, when you buy from a vetted seller that tests its units and includes a warranty. Confirm the unit matches your VIN, ask for the donor mileage, and read the warranty terms before paying.

What’s the difference between a used and remanufactured transmission?
A used transmission is pulled from a salvage vehicle and resold after testing. A remanufactured transmission is rebuilt with worn components replaced to a set standard. Reman units cost more and carry longer warranties; used units are cheaper and best when donor mileage is low.

How long does a used transmission last?
It depends mostly on the donor vehicle’s mileage and how well the new vehicle is maintained. A low-mileage tested unit, properly installed with fresh fluid, can last for many years. Ask for the mileage before buying.

Do I need to pay a core charge?
Often, yes. A core charge is a refundable deposit on your old transmission, returned when you ship it back. Confirm the amount and the return window before ordering.
