Is this something new or was it that way when you bought it? I wonder if someone installed a full manual shift kit in it.

I don't think that year had a kick down cable but if so check that its not broke if it does not have a cable then it has a TCM in which case that could be bad it may a clogged screen (tranny service) bad clutches inside trans bad or clogged valve body it is had to say but there are just a few common problems associated with the symptoms u have described one more thing it could also be the torque converter has gone or going bad
