Have you tried pulsing your calf in time with the walk you want to achieve? I'm still very tired, so it makes more sense in my head than I can find words to explain.
My trainer has me pulse my calf - not kick, only flex the calf muscle as it rests against the body - and for added emphasis I have to move my hips to help open up the motion for the leg. It's a lot like patting your head, rubbing you're belly, hopping on one foot, and singing the alphabet backwards simultaneously. The right calf pulses as the right hip rises towards your right shoulder - same for the left side. The outside rein stays low near the neck and maintains a solid contact with the mouth. Your shoulders are soft and straight. I'd you ride with a whip, it also helps to lightly brush it along the outside flank as that leg rises. Start with the reins at a length that maintains contact comfortably for the horse and gradually increase your length as the horse stretches forward more and more.
Clear as mud? Build up adding what you're doing until you find the combination that works. Then, gradually take the aids away.
