Ford Fiesta: Manual Transmission - 6-Speed Manual Transmission – B6 / Manual Transmission - Overview. Description and Operation

The B6 6-speed manual transmission is a fully synchronized transmission including reverse gear.

The 1st and 2nd gears are triple cone synchronized. The 3rd, 4th, 5th, 6th and reverse gears are single cone synchronized.

The function of the transmission is to move the vehicle from a rest position to motion. This is done by transferring the engine torque, through the transmission, to the front wheels. The transmission input shaft receives power when the clutch is engaged. Torque flows through the input shaft to the drive gear. The forward gears are selected by a selector mechanism. The helical-cut forward gears are in constant mesh with the corresponding gears on the opposing shaft. Reverse gears have helical-cut teeth and are engaged through the reverse shift fork and synchronizer.

The manual transmission is controlled by a floor-mounted gearshift lever located in the floor console. Connection between the floor-mounted gear shift lever and the manual transmission gear shift control mechanism is made through 2 shift cables. The clutch pedal disengages the clutch allowing the transmission to shift from one gear to another.

The B6 manual transmission is shifted internally by 4 shift forks. The reverse gear output shaft shift fork controls all reverse shifts. The 1st/2nd, 3rd/4th and 5th/6th shift forks control all forward gear shifts.
