How'd it do at the track... big #'s?

I would think it's time to go and see someone who is capable of diagnosing the condition... when you start guessing and then start swapping parts it can be a long and winding road! Not to mention you could easily create more problems than you already have.

By your description of the symptoms I suspect an engine issue, not a tranny issue.
