Help drive on bumpy roads

[Dice Roll]

My Michelin Defender 22" tires are smooth as glass with CCD and stock shocks. The ride on smooth, bumpy, pretty much any road is flawless.
Regarding Trans shifting, reset your PCM so everything learns again. I did mine, because I bought it used, and it was jumping gears going from 2 to 5 or 6, jerking when slowing down. Now my Expedition shifts flawlessly and learned my driving habits.
This is especially important if there ae multiple drivers. I mostly do slow takeoffs, coast to traffic lights and use cruise control highway and local.
It's been months now since the reset and mine is still shifting smooth.

I’m talking about in sport mode, trans holds gears in crazy ways and I can take it for long. Only one stretch of road I use is even really worth using it for.

im basically the only driver this thing has ever seen since new.
