The Ultramafic is similar to the Dynaflow in that it stays in high range all the time and uses a torque convertor. Where the Packard is different is that there is a direct drive clutch that locks the torque converter up after a certain speed is reached, depending on throttle position. The "shift" that you are noticing is the direct drive kicking in.
