Transmission problems are common in this model, often as a result of a failed front pump. The pump loses its ability to create hydraulic pressure, which an automatic transmission needs to function. A sign of front pump failure can be a whine type noise.

    MINE WILL SLIP, WHEN GOING AT AN EVEN SLOWER SPEED, TRYING TO GO UP A GEAR, IT HUNTS FOR THE GEAR FOR AWHILE AND THE ENGINE REVS, BUT CANNOT FIND THE GEAR FOR AWHILE. THEN IT FINDS THE GEAR AND IT IS FINE.

    Whining noise in low gear, changing frequency as it slips into 2nd gear. Some of the same noise as it accelerates in 2nd gear. Not noticable after gets in 3rd and 4th. Ford dealer says it's common and not a problem as long as the car isn't loosing power. (DUH).
