Well, if you want to test the MDS theory, just disable it and see if it still happens. You do that buy hitting the gear change button on the steering wheel. You should enable the eco and the selected gear displays in the cluster.

If you have the limiter slip, that could be your source and if so would likely be normal behavior.

My truck, 2023 Laramie, also does this when letting off the gas. Sometimes it's significant. Doesn't happen all the time either. Just whenever it feels like it.
