Ford fiesta 2011 with 120000 mile no rust, looks great,
some transmission sensor is fault and after running a little you could feel that is jump out from gear then come to normal when this happen,
appear on dash board : "transmission malfunction service now " and the engine light is on all the time , the car is still running .
Mechanic recommend to fix ASAP , so if test drive, no more than 30-40 miles per hour .
