93 ZJ 4.0L/AW4/249 "Slipping" at highway speed
While driving over 45, and especially when not under acceleration or load my jeep will jump about 250-500 rpm (rpms go up) and I can feel a loss of power.
It only does this for a second ,literally, or maybe two, then rpms drop down to normal and its fine. It is intermittent. During a 1700 mile road trip it happened around a dozen times. Has not thrown any codes and runs very well other wise.
