Electronic Operation

4EAT System Electronic Components.:

DESCRIPTION
The electronic system controls the transaxle shifting in forward speeds and torque converter lockup by means of solenoid operated valves. These solenoid valves when energized (ON) actuate friction elements (clutches and bands) to control shifting in the planetary gear. The shift timing and lock up events are regulated by the control unit in programmed logic and in response to input sensors and switches in order to produce optimum driveability.
