Default 4L60E slips in all gears.

I have a performabuilt level II paired with a yank ss3500. Starting a month or so ago when the converter would lock up it would surge about 3 or 400 RPM's when i hit the gas. After about 5 minutes of driving today it got much worse. Almost as if the converter was locking and unlocking but I believe it was just slipping. Now the converter will not lock up at all and it feels like the transmission is slipping in every gear. I can feel the transmission shift gears fine. The RPM's just stay up. First thing is first. I think I'm doing a fluid and filter change tomorrow. After that I'm not sure what to do. Does it sound like a converter issue or a transmission issue? Im hoping its the verter but a rebuild from performabuilt isnt much more. Opinions?
Thanks in advance.
