Coast Clutch Solenoid (CCS)

DESCRIPTION

NOTE: On certain applications, the coast clutch is controlled by the PCM in the overdrive position (TCS OFF) in gears 1,2, and 3.

The coast clutch solenoid provides coast clutch control by shifting the coast clutch shift valve. The solenoid is activated by pressing the transmission control switch 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.

SYMPTOMS
Failed ON - third gear engine braking with OD range selected.

Failed OFF - no third gear engine braking in overdrive cancel.
