Symptom Chart

WARNING: This page is about a different car, the 2020 Ford F-150. However, it is still accessible from the selected car via links, so may be relevant.

For F clutch operation, REFER to: F Clutch .

Condition Possible Sources Action
F clutch does not apply SSF mechanically stuck OFF INSTALL a new solenoid. REFER to: Shift Solenoids (SS) .
F clutch control valve stuck OFF DISASSEMBLE, CLEAN and INSPECT the F clutch control valve. If the bore or valve is damaged, INSTALL a new main control valve body. REFER to: Main Control Valve Body .
F clutch latch valve stuck OFF DISASSEMBLE, CLEAN and INSPECT the F clutch latch valve. If the bore or valve is damaged, INSTALL a new main control valve body. REFER to: Main Control Valve Body .
