There is a trans controller for an RE, but it's almost 800 bucks. I feel like I remember somebody putting a 727 valve body in a 46re, but I'm probably mistaken. Maybe check www.car-part.com to see if there is a 518 near you. Might pick up a good rebuilder fairly cheap.
Care to elaborate on this at all? I’ve looked (a few years ago) for a stand-alone 46RE controller and came up empty. Few guys on the Dakota sites were trying to figure it out but no one I could find had one running. Any links or info?
