Trans is slipping. Not unusual symptom. Sometimes you can get lots of miles out of it if you get your foot of the accelerator as it gets ready to shift. Whenever it overspeeds (revs), that's a sign of the trans clutch not locking in (the trans applies hydraulic pressure to a band to lock in the clutch pack). If you continue to let it do this, you'll wear out whatever is left of the lining.
