The Ty856wb7ja Subaru WRX STI 6-speed DCCD Helical Limited Slip Differential (LSD) transmission is an essential component of the high-performance Subaru WRX STI. This transmission is specifically designed for the 2015 and later models of the Subaru WRX STI, providing an enhanced driving experience with improved traction and handling.
The Ty856wb7ja transmission features a 6-speed manual gearbox, which allows for precise gear selection and an engaging driving experience. It is equipped with Subaru's DCCD (Driver Controlled Center Differential) system, which allows the driver to switch between three different modes: TORQUE SPLIT, 100% TORQUE TO REAR, and 50/50 TORQUE SPLIT. This system provides excellent traction and allows for optimal performance in various driving conditions.
One of the standout features of this transmission is its Helical Limited Slip Differential (LSD). The helical LSD provides smooth and predictable power distribution between the wheels, reducing wheel spin and improving traction. This results in improved cornering stability, better acceleration, and overall improved handling. The LSD features a 3.54 final drive ratio, which provides a good balance between acceleration and fuel efficiency.
The Ty856wb7ja transmission is also compatible with the Ty856wb7ka and Ty856wb8ka Subaru WRX STI transmissions. These are identical in design and function, but they feature different final drive ratios. The Ty856wb7ka transmission features a 3.90 final drive ratio, which provides even better acceleration, while the Ty856wb8ka transmission features a 4.10 final drive ratio, which provides improved fuel efficiency.
In conclusion, the Ty856wb7ja Subaru WRX STI 6-speed DCCD Helical LSD transmission is an excellent upgrade for any Subaru WRX STI owner looking to improve their vehicle's performance. Its DCCD system, helical LSD, and various final drive ratio options provide an exceptional driving experience, making it an excellent choice for anyone looking to enhance their Subaru WRX STI's performance.
