The STI 6-Speed transmission was designed to handle the additional torque of a the 280HP STI, as well as the potential race modifications that the car may be subjected too. Conservative at 280HP, many have subjected this transmission to 500 ft/lbs of torque abuse without suffering failures compared to high failure rate of the WRX 5-speed. Designed to address the weaknesses of the standard 5-speed, the 6-speed transmission is split transversely, instead of the longitudinal design of the 5spd. This design greatly strengthens the torsional rigidity of the case itself as well as the shafts and gears. An added oil pump allows for better lubrication of the gears as compared to the "splash" lubrication system of the 5-speed.
