Trans is out of control

[Bgarbo]

Howdy, I have a 2011 1500 5.7. My shifting points are all over the place at around 50 mph and up. It's always searching. Can't pull my camper at all. Any ideas would be greatly appreciated. Thanks in advance.

Does your truck have a Tow/Haul mode button? If so, use that when towing.

If not, when pulling your trailer you can always shift out of full auto and down a gear.
