Transaxle has 4 shift solenoids in the valve body to control engagement speed and throttle pressure for shift feel. Torque is distributed to front and rear wheels at all times to maximize traction of 4WD vehicle. The A-540E and A-541E transaxles feature a torque converter with lock-up clutch, 4-speed planetary gear unit, differential, hydraulic control system, shift solenoids and electronic control system. The A-541E transaxle has an additional shift solenoid in the valve body to control engagement speed and throttle pressure for shift feel.
