Bad idea for a street car. Most, if not all of the reverse patern valve bodies are manual shift, meaning you loose "D", no more automatic. You have to shift through every gear up and down whenever you drive it, it will get old real quick. And it won't be safe on wet or gravel roads because when you shift up or down, it hits hard and could break the tires loose.
