The transmission mimics your driving habits, so if you tend to drive slowly, accelerate/decelerate slowly, the transmission should shift smoothly.
I tend to have moments of pure adrenaline rush and tend to drastically change these habits on a whim. It's when the adrenaline wears off and I go back to a smooth drive is when I notice the "kick". IMO, I think it takes the computer & transmission some time to notice these changes and make the proper adjustments.
Remember, these high power machines are computer controlled. I KNOW we all have had our own "Office Space" moment and wanted to take a baseball bat to our PC's!!!!
A true test for your transmission "kick" would be to drive like a 95yr old granny for about a week. Pay close attention to the shift points and the "smoothness" of the shifts, whether shifting up or down. By the end of the period, if you are still getting a drastic kick, I would bet there's an underlining problem. If not, I would say you just have a stubborn computer than lags in response time to your driving habits.
FYI, a computer reboot can also fix the problem. I had this issue on my 2010 F150 and a computer reboot fixed the problem.
Good Luck!
