Description

The Subaru TY856WBEAA is a factory 6-speed manual transmission originally found in the JDM Legacy Spec B Tuned by STI. This low-mileage unit offers the robust strength of Subaru's STI-derived drivetrain, making it a superior upgrade over standard WRX 5-speed transmissions. It features a non-DCCD (Driver Controlled Center Differential) configuration, which simplifies installation compared to many STI transmissions that require complex electronic integration. This transmission is highly sought after for various Subaru projects, including Legacy GT upgrades, WRX conversions, Forester XT builds, and general high-horsepower applications. The package includes the transmission, OEM 6-speed shifter linkage assembly, and necessary transmission sensors. Ideal for those replacing a damaged transmission or upgrading from a 5-speed gearbox, the TY856WBEAA provides smooth and precise gear engagement. It is well-suited for both performance driving and daily applications, combining Subaru's renowned reliability with enhanced capabilities. The unit comes directly from a low-mileage Japanese donor vehicle and has been inspected. Note that a 3.54 final drive rear differential will be needed to match this transmission.
