a buddy of mine says he can supposedly get a type r tranny for a very good price. im really thinking that i will do this if i can get it for the price he says he can get it for but i dont want to lose gas mileage on long distance trips since my car will be a commuter from home to college for the next 3 years. that is the only drawback i can see or imagine from this mod. just wondering if someone else has done this to there gsr and what the outcome of it was on gas mileage and on performance. i think it will make a considerable difference in acceleration.
