  • Inventory from trusted salvage and insurance channels
  • Condition grade and odometer reading on every listing

Quality Control

Checked Before It Hits the Catalog

We do not list blind units. Engines and transmissions go through hands-on evaluation — operational checks, fluid review, and condition scoring — so what you see online reflects what arrives on the pallet.

When something does not meet our standard, it does not ship. That is the bar we hold for every shop order and every driveway delivery.

  • Engines: compression, leak-down, and oil condition review
  • Transmissions: fluid check, spin test, and solenoid evaluation

Questions & Answers

Everything you need to know about ordering a used or remanufactured engine or transmission from Jupiter Auto Parts — shipping, grading, warranties, fitment, and pricing.

Do you deliver outside of California?

Yes. Jupiter Auto Parts ships pallet freight from Torrance to all 50 states. Shop and garage delivery is free. Residential addresses pay a flat $250 rate that includes liftgate service.

What do the A, B, and C grades mean?

Grade A units typically have lower mileage and stronger test results for the application. Grade B units are fully functional with higher miles or light wear. Grade C is used sparingly — the grade is always shown on the listing before you order.

Can I negotiate on price?

Use the Get Quote button on any listing to submit your offer. We review fitment and unit condition, then reply within one business day with options.

How long does delivery take?

Most orders ship within 1–3 business days after payment. Freight transit adds 3–7 business days depending on distance. You receive tracking once the carrier picks up your pallet.

Does the price include warranty?

Yes — every engine and transmission includes our 2-Year Limited Warranty at no add-on fee. Coverage is time-based for 2 years from delivery — there is no mileage warranty. Visit the Warranty page for covered parts and how to file a claim.

How do I know the part will fit?

Search by year, make, and model, then send your VIN to support@jupiterautoparts.com or call (800) 241-8053. We verify engine codes, transmission type, and accessory requirements before you pay.

What checks do engines go through?

Listed engines receive compression testing, oil review, and operational checks when possible. Mileage is documented and a condition grade is assigned before the unit is available to order.

Do you sell manual and automatic transmissions?

Yes — our catalog includes automatic, manual, and CVT assemblies for domestic and import vehicles. Automatic units include the torque converter unless the listing says otherwise.

What if something is wrong after delivery?

Contact us within 48 hours at support@jupiterautoparts.com. We handle fitment disputes, freight damage, and warranty claims directly — and work with your installer to resolve the issue.
