Coast Clutch Solenoid (CCS)
WARNING: This page is about a different car, the 2004 Ford Econoline, 2004 Ford E450 Super Duty, and 2004 Ford Cutaway. However, it is still accessible from the selected car via links, so may be relevant.
The coast clutch solenoid (CCS) provides coast clutch control by shifting the coast clutch shift valve. The solenoid is activated by pressing the transmission control switch. Some applications have the CCS commanded ON in OVERDRIVE, first, second and third ranges. In MANUAL first and second, the coast clutch is controlled by the solenoid and also hydraulically as a fail-safe to ensure engine braking. In REVERSE, the coast clutch is controlled hydraulically and the solenoid is not on.
