Hard shifting 6 speed auto

My Sister in Law drove the new 08 dually and horse trailer over the mountain today for a rodeo. She called when she got there and told my Father-in-law that the trip went well, but the truck shifts very hard.

The Gross weight is around 25,000 or so. I drove the truck last weekend with about 16K total and didn't notice anything.

I am not sure if she is talking about the upshift or downshift. I will talk to her more on Sunday or Monday about it. I was just curious if you all have any insight or experience with this.

She was instructed to turn the tow/haul mode on and the exhaust brake on every time she starts the truck.
