I have a 2002 v6 auto just put a 2001 trans in it and having exact same problem, I was just told it's wrong transmission no figure. Said 2002 to 2004 same, emissions and speed sencor control is different so that's what's making speedo read crazy and rev limit also stays in drive unless i pull it down an shift. What a mess this has turn into bud. May be able to switch computer from the 04 but will either have to send it to dealer to have anti theft reset so it programs cluster,speed sencor, and key to your car hope you have more luck then me. If you can help me in anyway be much appreciated as well thanks
