Valve Bodies

The only issue you may run into is if the 727 valve body still has it's original separator plate. Most of the Trans Go kits I've seen utilize the stock plate. In this case look at the rear most set of bolt holes for bolting the valve body to the case. The middle hole needs to have an elongated slot instead of just a round hole in order to swap them between 904 and 727. It's an easy mod if it isn't.
