Sounds like it is going to need a rebuild/replacement. My 700r4 was working flawlessly after a corvette servo install. After I decided to do some "preventative maintaince" by changing filter/fluid, I experienced issues. 2nd slips on uphills, 3rd always acts wierd, revs up for about a second and then shifts. It's been doing this for a long time now since it first occurred.

You may want to try that lucas additive. I used it in mine recently and it helped firm up the shifts a bit, buying me more time until I get it rebuilt.
