The Ford Motor Co. AX4N automatic transaxle is a four speed unit with total electronic controls and is designed for operation in a transverse powertrain for front wheel drive vehicles. Currently found in Taurus, Sable and Windstar vehicles. The electronic system controls the transaxle shift speeds and torque converter clutch apply and release with solenoid actuated valves. These shift solenoids, when energized, coupled with the hydraulic systems valve body, actuate various multi-plate clutch packs and bands to control the various gear ratios through the planetary gear train. Line pressure is also electronic controlled with a solenoid and controlled by the Powertrain Control Module. The PCM moniters numerous input sensors and sends the proper signals for the gear ratio desired to produce optimum driveability.
