What you are buying
Upgrade your drivetrain with this premium JDM 2008-2014 Subaru WRX TY758 5-Speed Manual AWD Transmission. Featuring a highly desirable 4.44 final drive ratio, this JDM-spec gearbox offers significantly improved acceleration and gear-clutch response compared to the longer-geared USDM models. Sourced from low-mileage Japanese domestic market donor vehicles, this TY758 series transmission is the ultimate replacement for worn domestic units or a performance-focused upgrade for any “Narrowbody” or “Widebody” GR/GE chassis. With verified gear synchronization and smooth shifting performance, this authentic JDM component delivers the tighter gear spacing enthusiast builders demand for street and spirited driving.
