It seems that while I'm driving ~40mph down a road and theres a little jarring of a bump in the road, my 08 passion will jump up or down a gear, I can't tell which... but the RPM shoots up and it hesitates to go back into the proper gear

Normal.....especially if the speed is close to the computer's shift points. It only happens in the auto mode.

Yes, this is not uncommon. It has occurred with all three of my smarts ('08, '09 BRABUS, '12) and I believe it may have something to do with one of the sensors the transmission uses to determine when to downshift being momentarily "tricked" by the jarring motion.
