2003 thunderbird computer shifting points

Discussion in '1955 - 2005 Thunderbird Parts for Sale/wanted' started by Donmj, Mar 15, 2017.

  1. after battery is disconnected I'm told tranny computer has to reset the shifting points...had tranny rebuilt and I don't think it shifts correctly. Any similar problems ?? gas mileage dropped pretty bad also...any help appreciated ...thanks !
     
  2. I had my transmission rebuilt about a year ago.. no difference in gas mileage. At first I felt it was not shifting correctly . That went away. Sorry I can't tell you a time estimate on that. I drive just around town .. I was told that the computer was adjusting to my driving habits. My hubby says I drive hard. Whatever that means. I hope the adjustment happens to your bird also..
     
  3. My Transmission has the E code and I have not fixed anything yet. I wonder if I should just keep driving it without the overdrive lockup. Will this hurt the transmission or just my mileage.
