I don't understand why you would not want to mod the trans. A good shift kit is very easily installed, and a cheap mod. Then it depends how you drive it? If you drive it like you just stole it parts will fail. I am prob around 4 to 450 hp. Trans is built, and a trans cooler. HD u joints Auburn posi. Cheap insurance! It seems very solid. I do use it. but not constent abuse.
