Mack problems

Howdy guys.
I have a 05 Mack Granite CV713 dump truck. It has the Mack E7 with a 6 speed Allison automatic with about 258,000 miles. My problem is that it has really slow take off from a dead stop, but then gets going just fine, with or without a load on it. The second part is that it's starting to shift hard, mainly between 1st and 2nd gear. Other than that the truck runs fine and fast. You guys have any answers?
