The 4F20E electronically controlled automatic transaxle features a combination of electronic and mechanical systems to control forward gear shifting torque converter lock-up for quietness and economy and self diagnosis capability for simplifying trouble shooting procedures.
The electronic system controls the tranxaxle shifting in forward speeds and controls torque converter lock-up by means of solenoid actuated valves. These shift solenoid valves, when activated apply the friction elements (clutches and bands) to control shifting in the planetary gear. The shift timing and lock-up events are regulated by the TCM in programmed logic and in response to input sensors and switches to produce optimum performance.
