sounds to me like the tranny is startin to go... not really what you wanted to hear im sure. when the transmission starts act up there isnt normally much that can be done. it can be babied, the fluids can be changed and such, but normally nothing brings em back. unless something just got screwed up in the programming, then you may be in for a pricy fix... it's definitly something in the transmission.
