Shift Solenoids No. 1 & 2
WARNING: This page is about a different car, the 2002 Toyota Avalon and 2001 Toyota Avalon. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
In some gears, ECM provides a fail-safe system which will place transaxle in designated gear depending on solenoid failure. See Fig 1.
ECM controls transaxle shifting by delivering an output signal to operate the proper shift solenoid. Shift solenoids are located on transaxle valve body. See Figure. Shift solenoids are operated in accordance with gearshift lever position and ECM control. If a shift solenoid malfunctions, fail-safe gear may be selected. See Fig 1.
