Good afternoon group,

Having an issue with my 2020 Ram 2500 6.4...
18,000 miles

Trans doesn't want to up shift while accelerating while towing.
Small trailer or travel trailer.
Have to let off throttle completely for it to up shift.

Any application of throttle it wants to downshift, not able to use the torque of engine at all.
Have done a adaptive reset in transmission TCU and Throttle reset in PCM.
Anyone have this concern???
