On my 2000 Mustang, the automatic transmission doesn't seem to be smooth any more. It takes a while for it to get to 30-40miles speed. It accelerates little faster if I increase the torque to
2500-3000RPM. Any idea what could be wrong? Also the mpg seems to have reduced(to 17mpg city). I used to get
20-21mpg inside city. Is that normal?
