[Guiseppe]

Drove my truck from Tucson-Phoenix and back a week ago. That's the longest drive I have taken since lifting it. I noticed on my way there and back I would be doing about 80mph and the truck wanted to downshift. Ever since I have been back home it's been running crappy, climbing a tiny hill the truck is running a higher rpm, downshifts are more frequent and even normal shifts sometimes seem sloppy. Anyone encounter this or have an idea, I need help.. Thanks
