Question AT computer glitch?

We took the pickup to town today for some groceries and the lumber for the bed in the topper. It seemed to be shifting rough and late, and running too high RPM on the highway.

I checked the fluid in town and it was fine. Coming home it did just fine, running about 2100 at 70.

6.0 / 6sp. Is this weird or what ?????
