WARNING: This page is about a different car, the 2002 Toyota ECHO, 2002 Toyota Celica, 2001 Toyota ECHO, and 2001 Toyota Celica. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: Shift solenoids also be referred to as S1 and S2 solenoid.

ECM 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 selector lever position. If a solenoid malfunctions, fail-safe gear may be selected. See Figure.

NOTE: ECM provides a fail-safe system which places transaxle in a designated gear depending on which solenoid fails. In some gears, fail-safe system will not be activated and transaxle will shift to the fail-safe gear. See Figure.
