    We may be getting closer to solving this problem. I tapped into the line that feeds the rear six-pack like Richard suggested and I was able to get the rear to air up. (manually) Mike, at Newell believes it is in the DOT valve located above the transmission cooler (see pic) I'm going to try to get to it tomorrow but it looks really difficult to get to let alone turn a wrench, but I'll give it a good try. Hope these old bones don't crack!
