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.

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).

Replaced the transmission due to front end pump problem . Had a 12K and 1 yr warranty. Had a problem after about 6K and it was repaired. I haven't used the car much and put another 2K Miles on it. Now I am having problem with the reverse gear. Have trouble backing up have to race the motor to get it to move.
