How are used engines and transmissions tested before delivery?

Every engine undergoes a mandatory cylinder compression test (150-185 PSI minimum), digital endoscopic camera scan, and oil pan inspection. Transmissions undergo dyno bench testing, line pressure checks, and solenoid resistance tests.

What is included with your 1-Year Warranty protection?

Our standard 1-Year Unlimited Mileage Warranty covers internal lubricated engine parts (crankshaft, pistons, camshafts, valvetrain) and internal transmission gears and solenoids.

Do you charge a core deposit fee on engine or transmission purchases?

No! PowerX AutoParts offers Zero Core Charge on standard engine and gearbox purchases, eliminating upfront core deposits.

How fast is LTL freight delivery across the US?

Standard commercial freight shipping to auto repair shops takes 3 to 5 business days across the contiguous United States with full PRO tracking.
