FORD 4F27E TRANSAXLE SERVICE MANUAL – ATSG (Automatic Transmission Service Group)
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, along with the component application chart for each gear. 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.
