What is the difference between a remanufactured engine and a used engine?
An OEM used engine is the original factory-built engine pulled from a low-mileage donor vehicle. A remanufactured engine is disassembled, cleaned, and rebuilt, often with aftermarket parts. OEM engines retain original factory tolerances and are preferred by most mechanics. Blue Prism sells used OEM engines and transmissions, not remanufactured or aftermarket units.
Can you ship to any location in the USA?
Yes, we have a nationwide network, allowing us to ship OEM-used engines and used transmissions to any location across the United States, including major cities like Los Angeles, New York, and Chicago.
Do you also sell used transmissions as well as engines?
Yes. We also sell used OEM transmissions for all major makes and models, including Chevrolet, Ford, Honda, Toyota, Dodge, Jeep, and more. Every used transmission is an OEM-sourced unit from a low-mileage donor vehicle, tested by ASE-certified mechanics, and backed by a 1-year warranty.
Do your engines and transmissions come with a warranty?
Yes, every engine and transmission comes with warranty options up to 1 year, which applies to a major internal mechanical failure.
How long does shipping usually take?
Most engines and transmissions ship within 1–3 business days of your order. Delivery takes 2–5 business days depending on location. Customers in Phoenix, AZ, and California typically receive parts within 1-3 days. We ship to all 48 contiguous states via freight carrier.
How do I know if the engine or transmission fits my vehicle?
The most reliable way to confirm fitment is by using your vehicle’s VIN. This allows for precise matching based on your exact configuration. You can submit your details through the website or just call us at (430)-413-4976. We'll confirm the right part for your vehicle before you spend a dollar.
Are used engines and transmissions are tested before shipping?
Yes. Every part is inspected by ASE-certified mechanics before it ships. We run compression tests, check for leaks, and document the condition. If a part does not pass inspection, it does not ship.
