I'm sorry but implying that a 6-speed transmission is more efficient than a 4-speed because it has "2 more speeds" is uninformed. An apples to apples comparison of two transmissions' highway gas mileage would require each to have the same gear ratio. So what's the gear ratio of the 6th gear in a 6 speed and what's the gear ratio of 4th gear in a 4 speed? If they were the same, you would easily see that the DCT is more efficient than the torque converter because the DCT isn't wasting energy moving a bunch of transmission fluid around.
