c-4 code translation
hey all, i have a c-4 tranny thats been rebuilt with some high performance goodies on it, and i'm selling it on craigslist, but i just cant find info on decoding all the info.... some people are so dang particular on what they stick in their cars..... the code on the case near the tailshaft housing is C4AP-7A040-C EKjust because your car is faster, doesn't mean i cant outdrive you... give me a curvy mountain road and i'll beat you any day
