Mine has not experienced this issue but have had this happen with other vehicles - I can’t recall model or makes of each right now.
The speed sensing circuit may not be providing the correct info to the transmission computer and causing it to turn on/off shift solenoids at wrong times and pressure differences acting on clutches may be what you’re feeling. A good scanner should give you the speed info going to the ecu while driving so you could check if it’s accurately being measured.
