Grand Cherokee Limited, V8 While riding at 60-70 mph (3100 rpms) the tach shows engine revving 300 rpms then settle back to 3100. While riding at 60 -70 mph the engine frequently revs an additional 300-400 rpms and then settles back down to around 3100 rpms. It seems like a trans slip but the fluid is clean and full. This only happens at higher speeds.

The symptom you described, where the engine revs an additional 300-400 RPMs and then settles back down, can indeed indicate a transmission slip.
