No. 1 & No. 2 Solenoids

ECT ECU controls transaxle shifting by delivering an output signal to operate proper solenoid. Solenoids are located on transaxle valve body. See Figure. Solenoids are operated in accordance with shift lever position. If a solenoid malfunctions, fail-safe gear may be selected. See Figure.

NOTE: In some gears, ECT ECU provides a fail-safe system which will place transaxle in designated gear depending on solenoid failure.
