Ok I have a 2002 GT that i mostly stock with 62500 miles on it. I recently lost my 3rd and 4th gears while driving home. I thoght of fixing the problem and saving money but i think it is gonna me more of a hassle. I plan on putting a T-56 in my car but im not sure on which one to go with. I am also planning on making the car low 12 sec. and wanted to start from the back forward but now im in the middle. Would a T-56 be a good idea, and if so which modle?
