Why Choose This JDM Transmission?

• Ultra-Low Mileage: Japanese vehicles are typically driven far less than North American equivalents due to strict Shaken inspection laws and excellent public transit. This transmission has only 60,881 original miles — often less than half the mileage of comparable local used parts.
• Meticulous Maintenance: Japanese owners are known for rigorous maintenance schedules, premium fluids, and attentive care. You are not just buying a used part — you are buying a piece of Japanese engineering heritage.
• Direct Bolt-In Replacement: Designed as a factory-original drop-in fit for USDM and Canadian models. No custom fabrication required when matched to the correct engine code and VIN.
• Professionally Tested: Every engine and transmission undergoes compression testing, leak-down testing, and visual inspection before listing. We verify oil pressure, coolant passages, and internal condition.
• Cost-Effective Alternative: Why pay thousands for a rebuild or new OEM part when you can get a proven, low-mileage JDM unit at a fraction of the cost? Save money without sacrificing reliability.
• Backed by JDM Engine Direct: Our reputation is built on quality, honesty, and customer satisfaction. We stand behind every part we sell.
