If your fluid is black then the clutches inside the transmission are burning up, causing the slipping. Changing the transmission will take care of it, or you can get it rebuilt. If you do get another transmission, (1) take a good look at the fluid before you buy it and (2) change the fluid. If the fluid is not red like it should be, walk away from it.
