Diagnosis And Testing: Diagnostics: Fail-Safe
WARNING: This page is about a different car, the 2010 Mercury Milan, 2010 Lincoln MKZ, and 2010 Ford Fusion. However, it is still accessible from the selected car via links, so may be relevant.
With the fail-safe function, if any malfunction should occur in the transaxle system, the TCM will output a control signal, and control will be carried out to make traveling a minimum distance possible. If all shift solenoids malfunction, the TCM will cancel the output of control signals to the solenoids. If this happens, the automatic transmission gear shifting will be controlled by transmission fluid pressure circuits only and the gears will shift as shown in the following table below.
