    Speed,
    I've had the 4 speed (06) and the 6 speed (2011) in recent versions of GM's truck. Both trucks had 410 drive gears. While towing, I thought the 4 speed was a better unit. The top gear in the 6 speed is such that it can't be used in towing for long. It will up shift to 5th on even small inclines. As soon as that transmission get a wiff of a hill of any size it'll start down shifting. You'll be back to 3rd and fourth gear. Add to the nearly identical performance of the 4 speed and 6 speed, to the cost of making the 6 speed in your present truck work, I'm thinking it'll be lots of $$.
