JDM Subaru Legacy Spec B Tuned by STI 6-Speed Manual Transmission TY856WBEAA – Complete Swap Package with R180 Differential, Axles & Brembo Brakes

Upgrade your Subaru with one of the rarest and most desirable factory performance drivetrains Subaru ever produced. Available from J-Spec Auto Sports Inc., this JDM Subaru Legacy Spec B Tuned by STI 6-Speed Manual Transmission Package includes the highly sought-after TY856WBEAA 6-speed gearbox, matching R180 rear differential, rear axles, and OEM Brembo brake calipers.

Developed for the legendary Legacy Spec B Tuned by STI, this drivetrain package combines the strength and performance of Subaru’s renowned STI-derived 6-speed transmission with the refinement and drivability expected from Subaru’s flagship performance sedan. Unlike many WRX STI transmissions, the TY856WBEAA is a non-DCCD gearbox, making it an excellent choice for enthusiasts seeking STI-level durability without the complexity of DCCD electronics and controllers.

The Legacy Spec B Tuned by STI remains one of Subaru’s most respected and exclusive performance models. Built in limited numbers for the Japanese Domestic Market, these vehicles featured upgraded suspension, Brembo brakes, STI-tuned drivetrains, and numerous factory performance enhancements. As a result, components from these vehicles have become increasingly difficult to source and highly desirable among Subaru enthusiasts.

Whether you’re replacing a damaged transmission, converting a GT model to a 6-speed setup, building a high-performance street car, or upgrading a Legacy, WRX, Forester, or custom Subaru project, this package provides a factory-engineered solution designed to handle increased power and spirited driving.
