I got a 96 bronc that won't let me shift out of park. I replaced the back up switch and still nothing. It works fine if I crawl under it and shift it right on the tranny but that is getting old. I found a small leak on a sensor atop the brake master cylinder and I'm starting to wonder if thats whats jacked up. It looks like some type of pressure switch. Think it might not be letting me shift out of park because of the leak on that sensor?
