The claim is there, but the results are a bit.. inconclusive. It's also a bit biased, largely in part because of the ATA's influence, which also overlooks the fact that the rear end gears of autoshift trucks are at a higher ratio than 'matching' manual shift trucks. For an experienced driver who knows what they're doing with a manual, the difference can be negligible at best. For an inexperienced driver, perhaps they would be, but bad driving habits will impact the fuel mileage of an autoshift truck just the same as it will a manual truck.
Ultrashift, IShift, SmartShift, and Autoshift are just marketing names for automatic transmissions made by different manufacturers.

For the S10 and 1500, the manual was the NV3500 and the automatic was the 4L60E. For the 2500 and 3500, the manual was the NV4500 and the auto was the 4L80E. For their medium- and heavy duty trucks, manual transmissions from Eaton Fuller and Rockwell were available, while automatic transmissions from Allison were available.
Newer, computer controlled transmissions might have that problem if the VSS isn't working properly.
A manual transmission on a car is one that you control yourself via a stick shift. An automatic transmission is one that the car controls, based on your speed and incline.

There are basically three types of transmissions: manual, automatic and continuously variable transmissions (CVT). CVT is the only other type that would fall under the automatic category. transmissions for a ++++++ transmissions for a dodge truck
