Coast Clutch Solenoid (CCS)

WARNING: This page is about a different car, the 2004 Ford Pickup, 2004 Ford F550 Super Duty, 2004 Ford F450 Super Duty, 2004 Ford Excursion, and 2004 Ford Cab & Chassis. 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 (TCS) or by selecting the 1 or 2 range with the transmission range selector lever.
In MANUAL 1 and 2, 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. On power take-off (PTO) equipped vehicles, the CCS will also be on during PTO operation.
