Pricing

Used Engines
Most customers shopping used engines with Green Auto Parts can expect ballpark pricing between $900–$2,500 for popular gasoline engines and $2,000–$4,500 for many diesel applications, depending on mileage, options, and availability. Compared to buying new or remanufactured, these used OEM engines typically deliver 40–70% savings while still giving you a solid, warrantied replacement that’s ready to install.
Typical savings 40–70% vs new engines, fully inspected and tested.

Used Transmissions
For automatic and manual transmissions, typical used OEM units from our nationwide network generally range from about $650–$1,800 for compact and mid-size vehicles, and $1,500–$3,200 for trucks and heavy-duty applications. In most cases, choosing used over new or dealer-remanufactured means you’re saving 35–60% on the part itself, helping keep your total repair cost manageable without sacrificing quality or reliability.
Save 40–65% vs new, low-mile units with verified history.
Reviews

Aya Nakamura
“Bought a low-mile V6 from Green Auto Parts; shop said compression numbers were excellent and it runs like new. Saved over dealer pricing.”

Mateo García
“Transmission arrived clean, paperwork showed mileage and tests. Mechanic installed it quickly and it shifts smoothly, still performing great several months later.”
