My FIL has a tandem axle GMC Topkick with a 5-speed Allison and 250hp Cat diesel. I too was hesitant at first but after getting used to it I don't mind it. The first gear of this 653 transmission is sort of a "granny low" and isn't used in the normal automatic shifting sequence - it has to be selected manually. Even with 600 bushels of wheat on board there is plenty of axle torque to move in soft ground and climb out of fields up onto the road. In low gear the truck basically starts moving as soon as the brake is released, even when loaded in the field. If left in auto mode the truck will start out in second gear and it takes a lot of engine revs and torque converter slippage to make it start moving if it is loaded and there is any resistance to forward motion. Before he bought it we also looked at and test drove an International that only had a 4-speed 643 without the extra low gear and I'm sure glad we didn't buy it as I believe it would have struggled in tough conditions.
The PTO for the hoist on an automatic is probably easier to use than that on a manual transmission for someone new to this sort of thing. With the truck stopped but still in gear the PTO is engaged then the transmission placed in neutral. This starts the pump and you only have to move the lever up or down to work the hoist. No working the clutch to start and stop the hoist like with a manual.

Today's Featured Article - Hydraulics - Cylinder Anatomy - by Curtis von Fange. Let�s make one more addition to our series on hydraulics. I�ve noticed a few questions in the comment section that could pertain to hydraulic cylinders so I thought we could take a short look at this real workhorse of the circuit. Cylinders are the reason for the hydraulic circuit. They take the fluid power delivered from the pump and magically change it into mechanical power. There are many types of cylinders that one might run across on a farm scenario. Each one could take a chapter in
