Quality Used Engines & Transmissions for Sale

Used Engines and Transmissions for Sale — What Makes Junky Auto Parts Different

A new dealer-supplied engine typically costs $4,000 to $8,500 before labor. A remanufactured unit runs $2,500 to $4,500. A quality used engine for sale from Junky Auto Parts starts significantly lower — with the same OEM fitment, the same drivetrain compatibility, and a warranty that covers you for four full years.

Beyond cost, used engines solve an availability problem that new parts cannot. Some engine models are discontinued, back-ordered for weeks, or simply unavailable through dealer channels. Our network of verified salvage yards across the United States gives us inventory depth that dealerships cannot match — particularly for older vehicles, discontinued models, and low-production platforms.

Our 4-Step Inspection Process — Every Engine, Every Time

Step 1 — Visual Inspection Every engine is examined for cracks, oil leaks, rust, damaged components, and signs of prior overheating or collision damage. Units that fail visual inspection are rejected immediately — they never reach the listing stage.

Step 2 — Compression Testing A cylinder-by-cylinder compression test confirms internal engine health. Engines with low or uneven compression across any cylinder are not listed for sale regardless of their external appearance.

Step 3 — Mileage Verification We cross-reference each engine's mileage against donor vehicle records. We never estimate mileage or list engines with unverifiable records. Every listing shows confirmed miles.

Step 4 — Grade Assignment and Final QA Every engine receives a documented Grade A, B, or C quality rating. Only Grade A engines — those that pass every step without qualification — are listed in our standard inventory. Grade and mileage are clearly displayed on every product listing.
