If you’re planning the ultimate Subaru STI drivetrain conversion, this complete JDM GRB STI V10 swap package delivers everything you need from one of Subaru’s most sought-after performance platforms. Available from J-Spec Auto Sports Inc., this package includes the legendary TY856UB1KA 6-speed manual DCCD transmission, OEM Brembo brakes, R180 limited-slip differential, hubs, axles, shifter assembly, starter, and supporting drivetrain components from a genuine JDM Subaru WRX STI.

For years, Subaru enthusiasts have considered the STI 6-speed transmission one of the strongest factory manual gearboxes ever installed in a production vehicle. Unlike the standard WRX 5-speed transmission, the STI 6-speed was engineered to handle significantly more power, aggressive driving, track use, and hard launches. As a result, it has become the preferred upgrade for WRX owners, engine swap builders, and performance enthusiasts worldwide.

This particular transmission is the highly desirable TY856UB1KA DCCD gearbox, originally found in the 2008–2014 GRB/GVB Subaru WRX STI. Combined with the factory Driver Controlled Center Differential (DCCD), the transmission offers exceptional traction, durability, and driver control in both street and motorsport applications.
