A few days ago my transmission blew up at almost 60,000 miles. i had noticed it slipping and loosing torque 5,000 miles before hand, but it finally gave out. ive driven this trany really hard and im honestly surprised it lasted this long. Subaru warrantied it thankfully. with this new transmission, i notice, problably a 5% increase in hp/torque. ran a new 0-60 time coming out to be .6 second faster, in addition, my shifts being cleaner and faster. overall, huge difference in performance.
