I don't think your C-4 had a vacume kick down. It had a vacume modulator that told the transmission how hard the engine was working, by the vacume signal sent to it. The C-4 kick down is a small cable/linkage that is pulled when you floor the accelerator.

Your AOD has nothing but Throttle pressure to control the shifting and kick down.
