Do they still have lock-up torque converters.

Not sure if this is of help but you may have a DTC stored in history since you don't have a check engine light. An auto parts store could pull the code for you, if there is one, for free and that could give you a starting point.

Have you checked the throttle body to see if it is all gunked up/dirty? That is easy to get to.
Dirty throttle body can make the RPM jump up and down. Interesting that it does so after a long trip.
