Yep you probably have a broken Forward apply band and I see this pretty often on 00-02 models. This can be checked by dropping the lower trans pan and looking in a windowed out section in the case just to the passanger side of where the filter is. There is an apply pin that engages the Forward apply band and right where the pin makes contact is where the band will crack or break off, so you may either find a broken piece in the pan or look up and see cracks in the area. Unfortunately this means a full rebuild as the band is one of the last parts to come out of the trans.
