I've called them,but right away they say you can't "because it's for an auto trans".It's like when your mom or dad would just say"no,you can't" and you kept asking why not. Well, as far as i know, an auto trans also has the same wet-clutch setup ,right? As far as the rings,the engine oil treatment has the exact same ingredient.What i want to get out of this is more power,whatever it'll be and secondary is mileage.Lower operating temps and longer lasting parts.
