INTRODUCTION FORD 4F27E

Ford Motor Company in a joint venture with Mazda in Japan have developed a new design transaxle designed specifically for use in the Ford Focus, with the designation 4F27E. and Mazda designation is FN4A-EL. The new 4F27E transaxle is produced by Ford Motor Company in Sterling Fleights, Michigan.

This is a four speed. Front Wheel Drive, with fully electronic controls for the upshifts and downshifts, with 4th gear being overdrive. The individual gear ratios are achieved through two planetary gear sets connected one behind the other. The components of the planetary gear sets are driven or locked by means of four multiple plate clutches, one brake band and a one-way roller clutch. To minimize fuel consumption, the torque converter clutch is applied by the PCM in 3rd and 4th gears, depending on throttle position and vehicle speed. This unit is designed to use Mercon® V automatic transmission fluid.

The manual selector lever gives the driver a choice of “P”, “R”, “N”, “D”, “2”, “1”, and all ranges are explained in detail in this manual. It is also possible to operate an O/D cancel switch, located on the selector lever, to prevent the transaxle from shifting into 4th gear or to shift down to 3rd gear.
