Welcome to the site.
How many miles on the Truck/Trans?
If your referring to the final OD shift (OD) it’s fairly common with high mileage units. If OD is canceled, do you have slipping at the noted speeds? Torque Converter ‘shudder’ generally appears early on the final shift with throttle tip in. They used to sell a product called Shudder Guard before the Mercon V lube upgrade. If the old fluid is aged out DextronIII/Merc, servicing with Mercon V would have the latest protections.
If this is the symptoms, you might try servicing the unit to see if it improves.
