I wasn't aware that they had gone with their own ten speed for the 3/4 and 1 tons, but still not an Allison, correct? I am impressed with the ten speed in my wife's Escalade, very smooth, almost seamless shifting. You really don't feel the shifts unless you really put your foot in it and then the engine doesn't have to scream at 5000-6000 rpm's in a lower gear to launch it. It allows the 6.2's 460 ft/lbs of torque to get it moving.
