6-Speed Manual Transmission

The Subaru Impreza WRX STI TY856WB3KA is a complete 6-speed manual transmission package, sourced from JDM (Japanese Domestic Market) vehicles. This transmission is highly regarded for its robustness, precision engineering, and close-ratio gearing, which enhances acceleration and provides seamless shifts for an improved driving experience. This comprehensive package includes the 6-speed STI DCCD transmission, four-corner Brembo brakes with 5x114 hubs and rotors, aluminum control arms, front and rear subframes, axles, an R180 rear differential, driveshaft, and 6MT shifter linkage. The transmission features a front Suretrac LSD and a rear plated R180 3.90 LSD differential, with 5x114 hubs. This transmission is an excellent swap for the 2002-2007 Subaru WRX (GD chassis) and 2003-2008 Subaru Forester (SG9 chassis). It can accommodate considerably more power than stock 5-speed or automatic transmissions and is also a suitable option for daily driving thanks to its DCCD (Driver Controlled Center Differential) feature. The TY856WB3KA transmission features durable construction and advanced synchronizer technology for smooth and reliable operation under demanding conditions, making it a popular choice for enthusiasts prioritizing performance and control.
