The JDM Subaru Impreza WRX STi 6-Speed AWD Transmission with LSD Differential, Axles, and Starter (Version 7 GDB, TY856WB1AA gearbox) is widely regarded as one of the most durable and performance-oriented drivetrains ever offered by Subaru. Introduced in the legendary 2001–2002 Subaru WRX STi Version 7 (GDB), this gearbox became famous for its rally-bred strength, close-ratio gears, and confidence-inspiring AWD system. For enthusiasts, tuners, and builders, this complete drivetrain package is the ultimate solution for replacing or upgrading transmissions in WRX/STi builds. At jdmcarpart.com, we supply direct JDM imports like the TY856WB1AA gearbox, fully inspected, compression-tested, and shipped worldwide with warranty support.
Subaru’s 6-speed gearbox is often described as “bulletproof,” designed from the ground up for motorsport use. Unlike the weaker 5-speed transmissions found in earlier WRX models, the 6-speed was engineered with stronger gears, triple-cone synchros on the first three gears, and a robust case designed to handle the torque and stress of high-power applications.
