I rebuilt the trans in my '99 3.9 Dakota (had a different issue) but the bands were found to have chunks coming out of them. Mine had a flare on 2-3 shift. wasn't all that bad to do. and cost less to know I now have a good trans than it would have cost me to go get a trans from a junkyard. I just wish this truck had more engine. but I'm gonna run it in teh ground with the current one since the body is getting to the "not worth an engine swap" stage.
